But the danger of this full scale white noise appears to > be exaggerated. I have been running an SB2 for 3 years and a > Transporter for 18 months, and have never once experienced this > problem. I agree with Clive. I recently bought a McIntosh MC402 power amp and run the TP straight into it. My system hasn't sounded this good since I left analog in the early 90s. I sit there and just *listen* to the music. I haven't sat through whole CDs like this for many years. My speakers are inefficient at 86 dB. I didn't have to add attenuation. The sound at full volume (TP at 0 dB) is just about as loud as I need to hear it. The amp has more in it and this is part of what I think Sean was touching on when said the voltage levels weren't matched. That is, a preamp would match the output of the TP voltage levels better to the input of the power amp and my system would get louder. Right now full volume usually runs about 40 watts average wattage (with much higher peaks) on the 402. One interesting thing is I bought some Cardas Golden Reference XLR ICs thinking I would get 3 more dB into the amp but it turned out the volumes between the RCAs and the XLR connection was essentially the same. Maybe McIntosh attenuated to match. Clearly a sound improvement across the spectrum though. Costly but a noticeable improvement over my $140 cables. I had planned to buy a pre-amp but my system is sounding so good I'm in no hurry to touch anything. With the size of the Mc402, I don't have any room for a pre-amp either. I'd still like to get one if I could figure out a WAF way to arrange my components. Two things I'm missing are the tone controls for those rare occasions when I play some overboosted-highs "remaster" and for the 12v trigger - the McIntosh amp must be manually turned on and off without it. I also wish the TP had more volume steps. The lowest volume level is still a little loud - it's low but not barely audible. I noticed the Mc preamps have 99 increments. Also noticed the little ticking noise when the TP volume goes up and down. I assume this is some sort of digital volume control quirk. -David -- wireless200 wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=47520 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I didn't need attenuation. The 0 dB setting is actually just about right for maximum loudness I'd listen to. That said I'm going to go balanced to get that extra 3 dB out. Sometimes I need the amp to go to "11" ya know. I've got a request in for a pair of Cardas Golden Cross ICs. I was planning to buy those all along but the MC402 is sounding so good that I'm a little conflicted between the Golden Cross and Golden Reference. Not much price difference but the Golden Cross is always said to be warm, fluid, smooth while the Golden reference is more detailed. I always had a problem with my Krell and other amps being too bright. The MC402 is the first amp I've been able to sit down and listen to for a good long while without wanting to leave the room after three songs. IOW, it's already nice. I wondered if the Golden Cross' will take the smoothness to far. In any case I've read so many good things about the Cross' that I've decided to go with them. Finally! the TP DAC sounds very good through an amp I own. Still debating whether to buy a pre-amp or not. I was thinking about the c2300. I was very close to buying a c46 then noticed the 4k treble tone control doesn't roll off the top the normal way. It only rolls off a big hump around 4k but barely anything off the top few KHz. regards, David -- wireless200 wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46786 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I tried balanced out of the TP to the Krell I just sold and couldn't hear much of a diff. Maybe just the littlest bit. It was easy to A-B with both hooked up and I adjusted the volume to match them. I have also read where several people said they liked RCA better when they A-B'ed. Still, gotta love that *click* though when connecting the balanced connections. I plan to buy a pair of Golden Cross cables as I've heard they are very smooth. RCA and XLR are equal in price for those cables. I kind of like not having an external attenuator but no big deal really. As long as it's not one of the stepping or external boxes that I've seen. A small, fixed bullet-sized one would be ok.

I heard a high-end Mc system in the store on Focals and it sounded great. The Krell has a different "house" sound. I originally bought the Krell due to space considerations and didn't think the sound of the Mc integrateds was all that good. The Krell made about 20% of my music sound out of this world - I mean just delightful. The other 80% I had varying degrees of success. Anything with compression or boosted highs - wow - the Krell let you know it and not in a good way. I concluded one needs $5k or greater in the source before the Krell going to sound good over a large range of recordings. Basically you need a source that's true to good recordings and fixes or at least smooths over the bad ones. The TP doesn't fit the bill for that purpose. After I bought the MF, it made most of my recordings sound good but I lost that steller 20% and missed it. I don't care about coloration as long as it sounds sweet and musical hence my choice to move to the Mc. Further I'm going to try to TP straight into the amp bi-passing a pre. I think you're going to be feeling the pain with Theil's just as I do/did with my Aerials. Both are what I would call detailed speakers. I've heard Theils sound good with tubes and smooth sources but suffered in the same way as the Krell caused when they've been connected staright to an accurate source. I think you made the right choice with Classe' for your current setup. But, yeah, any digital input to a good DAC would be ok IMO. The DAC is where the rubber meets the road. It's going to come down to the DAC. I'm trying to avoid an outboard DAC but the next one I would try would be a MF Tri-vista dac.

Re: [SlimDevices: Audiophiles] output inpedance of the TP
Thanks Phil and others I think I've got a better understanding of what's going on there. Actually I understand the Wiki article just fine. I derived the theorem in 2nd year EE and have an MSEE. It's covered in every Circuits 101 class. Actually I think opaq is a little confused about what it says because the reason the theorem doesn't apply for my question wasn't due to the parts about power transfer or efficiency. Of course thankfully others stepped up with very good clear-headed explanations as to what was going on. Thanks to Phil and others for that. There were some very good replies. As far as needing 400 watts. I have inefficient speakers. Aerial 7Bs (rated 86 dB but measured less in Stereophile). They drop to 4 ohms in the bass region. I thought about getting an MC252 but the MC402 was reommended for my speakers. But probably either one would work. Follow the old adage for cars - get the biggest engine you can in the model you want to buy. :) I've owned a 400 watt Krell and a 300 watt Musical Fidelity with these speakers and, yeah, they could get loud but I don't think they were overkill by any means. Also of course it has to do with delivering peak power when it's needed. Certainly the Aerials swallow the 100 watt Marantz I have hooked up to them now. It'll get loud too but you can tell they need something with more power or ability to deliver power when needed. Also nothing meant against Sean by quoting that link. No need for me to go and re-explain the theorem when a link would do. I was looking for a little more explanation and others nicely stepped up. regards, David -- wireless200 ---- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

The Mcintosh mc402 gives 2, 4, and 8 terminals as "output load impedance." Musical Fidelity Kw550 specs a 50 ohm "output load loop impedance." Of course LC effects will distort the waveform (or even eliminate it at certain frequencies due to filtering effects). I guessing if there were no LC effects, then there would still be valid reasons for the relatively different impedance values between source and target. Again as stated earlier I think it's to generate maximum voltage across the input. But if that were absolutely the case then speakers impedances should be as high as possible. The physical machinations required of a woofer or tweeter must account for this difference. -- wireless200 ---- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Yes, this is a whole 'nother matter - LC effects. Not really wanting to get into that at this time for my purposes. Another thing I was curious about. I've heard that pre-amps are needed because often preamp DACs and volume controlled CD players, etc., don't have the output power suitable for a power amp input and that a preamp is needed. I want to use the TP as a pre-amp and avoid buying a separate pre-amp. That's why I'm asking these questions. Although it's good information I don't really want to hear "other's are doing it"... I like to know what the pros and cons are from a technical perspective. An MC402 by itself is pricey and if I've got to buy a pre-amp too then I've got to take that into account for my budget. regards, David -- wireless200 wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Obviously, the theorem is not wrong http://en.wikipedia.org/wiki/Maximum_power_theorem but I'll take your word on the desired relative impedances being the best. Why is this and from there how do you reconcile a speaker's typical impdendance with a typical SS amp's output impedance (high back to low)? regards, David -- wireless200 ---- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] output inpedance of the TP
Hmmm, that's interesting... the TP has a 100 ohm output impedance and the McIntosh has a 10k ohm input impedance (20k ohm balanced). What does this mean as far as sound quality. Matching impedances result in maximum power transfer so this doesn't bode so well, does it? I don't know exactly. -- wireless200 -------- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Transporter straight into an amp
I'm thinking about buying a nice amp and running the transporter straight into it. So far I've tried the TP with a Krell integrated 400xi. The well-recorded CDs I have sounded the best I've ever heard but the other 70% were a mixed bag. I think the Krell was just too good - no forgivness there! Any compression or boosted highs just shredded my ears. I'm running a Musical Fidelity A308 dual-mono which sounds pretty good too but I'm considering running the TP either straight into a Ayre V5Xe or a Mcintosh C252 and trying that. The MF makes about 80% of my CDs sound good but the good ones aren't as good as they were on the Krell. The MF has a nice warmth to it. Any of y'all doing that? I don't really need a pre-amp as the TP would be the only input. I'm also thinking about going to an all-tube setup but that's another story. regards, David -- wireless200 -------- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46255 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Balanced vs. unbalanced
The way I understand it, in the TP after the D/A is peformed the signal is in a combined state (unseparated) and to get it to balanced, it has to go through another set of circuitry to separate the signals into balanced componenets for the XLR output. Whereas the RCA output does not go through the additional circuitry. And at the other end (e.g., my Krell) it has to go through the reverse process to recombine the signal. In other words keeping the signal on the unblanced RCA path results in a circuit path with fewer components.

Did you A-B between the balanced and unbalanced? I guess you couldn't exactly do that since the SB doesn't have a balanced output. Can you do that on the DAC 1? Or are you comparing the analog out from the SB to the balanced out of the DAC 1? I came very close to getting a DAC 1 Pre to go with my SB but ultimately decided on the TP. regards, David -- wireless200 -------- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=42042 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Balanced and RCA at the same time
Does it make any difference if the balanced and RCA outputs are hooked up at the same time (to A-B them)? That is, does it cause the impedence or anything to change to simultaneously place two loads on the outputs? The TP doesn't have a selection for the output does it? regards, David -- wireless200 wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=44762 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I'm going to try my TP with Zu cables (Gede XLRs) which I like a lot with their RCA connectors. I have a 400Xi as well and I get the impression Krell do like balanced with them pushing their CAST system and all. -- wireless200 ---- wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=42042 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
