Re: [SlimDevices: Audiophiles] Super Squeezebox Project
Thanks JeffW! Actually I used clear acrylic sourced from a picture frame and cut to fit with a GE plastics cutter knife. The blue color comes from a gel optical filter film (available from sound reinforcement stores or Amazon) cut to fit the clear acrylic and glued from the inside. It's a little oversized so the glue won't show up in the actual display window.

Re: [SlimDevices: Audiophiles] Super Squeezebox Project
Well fellas, it's been almost a month since my last post. All this time I've been sourcing parts for my project. The hardest part to find was the 20 pin FPC cable for the display. It arrived yesterday. I have put all the pieces together for the initial test. It's looking pretty good methinks. The front panel is only a prototype I built. I'm having the display cutout done by Front Panel Express. It should arrive next week. In the meantime, this one has let me experiment with different display colors. I settled for a nice deep blue color. Matches great with the blue LED on the power supply unit. Since I am basically just using the digital outs, I added a 1:1 pulse transformer and BNC connector. The analog stage has new Neutrix connectors, but otherwise stock Notice the extensive shielding of the display area. I am also using ERS (RFI/EMI reducing sheets) material liberally inside the case of both main unit and power supply. New IXYS HEXFRED diodes were added to the PS unit, along with a Auricap film bypass for the smoothing capacitors. The power connection is via high quality XLR Neutrix connections. I custom made a cable using Neutrix connectors and silver teflon wiring. A couple of TDK ferrite snap-in cores were added to the cable. This thing is sounding fantastic.

Re: [SlimDevices: Audiophiles] Super Squeezebox Project
Actually you CAN get some magnetic shielding with aluminum. A 1/4 inch thick piece of aluminum will drop a 60Hz magnetic field by 5-10db. So putting a linear supply in a thick walled aluminum enclosure is not just cosmetic. If I remember correctly the thickness is directly proportional to the attenuation, so don't skimp, use massive thick heavy stuff. Even with a linear supply you can get a significant amount of radiated noise caused by the secondary of the transformer ringing at high frequencies when hit with the current spike from the recifiers. This effect is worse the higher the quality of the transofrmer. Its very easy to damp this ringing with a resistor and capacitor (the two inseries) placed across the secondary of the transformer. Almost no commercial supplies have this. I tried it on mine and it made a significant difference. Jim Haggerman has a paper on this on his web site if anyone wants to look at it. Its a bit complicated to find the exact values to use, but it turns out that damping too much doesn't hurt anything. So I came up with a set of values that worked for every one of the transformers in all my equipment, 330 ohms and .022uf. I put these on everything and the results were startling, the acoustical space of the original recording is now much more a part of the listening experience. Its probably the largest improvement in sound for any one thing I've done. And this one IS measurable. With my scope set to its highest gain setting I could always see some high frequency hash on the supply rails and the audio outputs of pretty much anything in the system. After this change the hash was gone. The scope trace is just a thin line now (with no signal). The SB linear supply was one of the biggest offenders, since it runs at a fairly high current it has large caps, which result in very large current spikes. I also used a high quality transformer which had very low losses, unfortunately that means it rings like a bell at 200KHz! Cheap crud transformers actually don't ring as much beause their internal losses tend to damp the resonances. I would definately recommend this simple tweak if you are using a large high current supply, it will almost certainly have this problem.

Also, it is obvious that great care was taken to miminize RFI/EMI interference by carefully routing the PCB traces and keeping them very short. The absence of any wires aside from the antenna and display connections is excellent design practice. So, there's an obvious advantage in using SMD components in this regard. It's not just about manufacturing ease. The tiny caps and resistors do allow for shorter signal paths and better noise rejection. Now that I've seen the innards of the SB2, I'm a little weary of the massive modifications done by the well known outfits. The replacement caps often have long leads that are hard to dress on the PCB. I would venture the benefits of these high-performance parts are somewhat negated by the long leads. I am planning to replace the RCA jacks with something better. But even by doing this, you are introducing some extra wire in the signal path. The original jacks are soldered directly on the board... I'm figuring that even a straight transfer to a larger enclosure is going to have sonic benefits, even proper care is taken. For instance, the display PCB can be shielded from the rest of the electronics. This should prevent stray RFI emissions from entering the audio circuits. -- crooner SB2 SB3 with Custom Linear Power Supply Lite Audio DAC-60 Tube DAC VPI Scout with Benz Micro Glider M2 Audio Research PH3, SP16L and VS110 Vandersteen 2Ce signatures, 2W subwoofer. crooner's Profile: http://forums.slimdevices.com/member.php?userid=3379 View this thread: http://forums.slimdevices.com/showthread.php?t=34291 ___ audiophiles mailing list [EMAIL PROTECTED] http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Super Squeezebox Project
Got my Squeezebox 2 today. Man that was fast! The seller was in Colorado and he sent it DHL Express, for just $10 SH. Very nice of him. The unit is in mint condition, virtually brand new. It looks so nice that I almost feel guilty about taking it apart. The Squeezebox 2 is the unit that pretty much started it all, in the audiophile sense. Perhaps a collectible in the future? I know Sean Adams at only 27 is quickly becoming an icon and I'm sure he'll be joining the likes of John Curl, Jim Bongiorno, Steve McCormack and others. If he hasn't already! I have read a lot about the SB2's appearance, comparing it to an alarm clock and such. But you know what? Looks great in person! The rubbery plastic of the case is great. Even the remote has that rubbery plastic on it. Audio Research remotes are also rubber coated. So perhaps the cheapie remote thing started when the SB3 was released. In any case, I have the lighted TP remote and will use that one with my SB2... -- crooner SB3 with Custom Linear Power Supply Lite Audio DAC-60 Tube DAC VPI Scout with Benz Micro Glider M2 Audio Research PH3, SP16L and VS110 Vandersteen 2Ce signatures, 2W subwoofer. crooner's Profile: http://forums.slimdevices.com/member.php?userid=3379 View this thread: http://forums.slimdevices.com/showthread.php?t=34291 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

For his purpose, I've just purchased a SB2 via eBay that will be modded and then transplanted to a custom made audiophile grade enclosure to match my other components. The enclosure will feature a thick brushed aluminum front panel. There's the option of having a the linear power supply incorporated (and properly shielded) inside the enclosure or using a separate box. For my present SB3 setup, I've been using a Power One HB5-3/OVP-A based DIY power supply with excellent results. See: http://forums.slimdevices.com/showthread.php?t=32802 For the Super Squeezebox, I will be using a larger Condor MD5-12-OVP-A medical grade linear supply. This unit is rated at 12 amps, which sounds like overkill, but for the Super SB nothing less will do :-) As for the mods on the SB2, I plan to do them on the analog and digital level. For this purpose, I'm considering Bolder's full mods. However, I might just do them myself. Once the Super SB is finished I plan to do comparisions between it's analog outs and the digital out fed to my Lite Audio DAC60. My present SB3 will also serve for comparisions as a stock unit. I think this is going to turn out pretty sweet. I even bought a lighted remote to go with the new unit. Quite frankly, my current stock SB3 with custom DIY power supply and DAC60 sounds pretty sweet as it is. But the adventurous in me is eager to work on a new project. It will surely keep me busy in the months to follow. Stay tuned for updates on this Super SB Regards, crooner I'm sure the thick brushed aluminum front panel and the larger Condor MD5-12-OVP-A medical grade linear supply, will make a big improvement in SQ.

Re: [SlimDevices: Audiophiles] Super Squeezebox Project
While adding a linear supply to the box might do some good, depending on who you ask, there is a good reason not to make it too big. A 12A supply used where only a 1A or so supply is required will be capable of destrying a PCB if something goes wrong in the SB. Industrial linear power supplies are usually built with EI core transformers. The bigger the core, the greater the leakage of the magnetic field from it. A smaller supply will be less likely to pollute your audio with stray magnetic fields. If you want the thing to be heavy, as it must be for true high-end status, add some bricks or lead shot.

The 12A supply was very cheap to let it pass. However, it doesn't seem to be too big. Just slightly larger than the 3A supply. Same open frame construction. Specs do not call for mandatory forced air cooling, so no fan is required. The most obvious differences being the slightly larger PS, filter caps and four TO-3 regulators instead of a single one in the Power One unit. But I understand your concerns about heat and EMI radiation. I'll probably just enclose in a dedicated Context Engineering box, just like the other one.

Re: [SlimDevices: Audiophiles] Super Squeezebox Project
Well... At first I just wanted an enclosure to match the rest of my stuff. Obviously the SB3 would not be an option because of the form factor. The SB2 lends itself quite easily to custom applications, so I got myself one. Now, even though my current setup is musically satisfying, I figured why not go the extra mile and do some improvements on the circuit as well. I love my Lite Audio DAC60, but according to some, modifying the analog section of the SB can yield excellent results. So much, that an outboard DAC may not be needed... The digital mods are also quite interesting. I particularly like the addition of a 1:1 transformer in the SP/DIF output as done by fellow member Gary. The plan is to improve the SB2 in both analog and digital outputs and then decide if I'll keep the outboard DAC. -- crooner SB3 with Custom Linear Power Supply Lite Audio DAC-60 Tube DAC VPI Scout with Benz Micro Glider M2 Audio Research PH3, SP16L and VS110 Vandersteen 2Ce signatures, 2W subwoofer. crooner's Profile: http://forums.slimdevices.com/member.php?userid=3379 View this thread: http://forums.slimdevices.com/showthread.php?t=34291 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
