Re: [SlimDevices: Audiophiles] New AKM 4490 DAC
It really depends on what it drives , most active amps and preamps have input impedance of 10kohm or more in some cases much more . So it's not per Defenition a problem driving a power amp directly . With the wrong power amp or preamp you can have an issue . If I remember rigth some old professional standards have 600ohm as recommended input impedance such a component would be a problem for the touch to drive , especially if its output impedance varies with frequency ( or the driven amp,or preamp has similar issues varying input impedance . So just take care when pairing the Touch almost every normal component is ok . But some old pro stuff may not be ok or some of the more esoteric audiophool equipment , where they left sensible design practice in the dust can be issues . I have tried some of my squeezeboxes with a semi passive gamut preamp a decade ago, and it sounded polite , just as suggested :) but that's not what I consider good equipment today .. Their are two ideas here . Source very low impedance preferably 0 ohm no variation in the audible range 20-20k amp high impedance 20kohm or more also linear within 20-20k . Impedance matching source and sink should have the same impedance ( say 600ohm ) and also the reactive parts should match and be close to 0 so both source and sink should be close to resistive with the same impedance , a more old school aproach . As an off topic side note in industrial electronics ( where I work ) we have ditch both these ideas in the 60-70's going for current source transmission of analog signals ( in the rare case of using an analog signal at all ) 0-20mA or 4-20mA this is much more resilient to long cable lengths etc than trying to send a voltage the sender is a current source ( near infinite impedance ) and the recieving end is like 100 or 500 ohm ( preferably 100ohm high impedance inputs are prone to noise pickup , low impedance inputs basically " shorts " incoming noise ) the nice thing is that impedance can be whatever within a certain range current is current in a series circuit , this topology is linear until the source can't drive the circuit anymore usually due to the power supply which is usually 24 volts if that can't make 20mA there is a problem , but all is fine until you hit the limit . I think Krell used this idea for a while with some proprietary interface between amp and preamp , naturally touted as a revolutionary idea :) ( besides the fact that any nearby industry had this for decades ) Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.

Re: [SlimDevices: Audiophiles] Post on AudioVero's Acourate...
I started using a TacT room correction system about 2000, including the preamp/processor and digital amps. Room correction became the one thing I would not be without. The TacT system allowed 9 presets for different correction curves. After much experimenting, I eventually settled on 2 or 3 that I used for different music...rock, acoustic jazz and classical. They were all set to address the fundamental room issues in the bass region, but with small tweaks to satisfy my particular preferences. Dr. Uli Brueggemann was a regular contributor to the TacT forum, contributing his free "Good Vibrations" software which added additional features to the TacT program. Uli then went on to create his Acourate system, and he has extensive experience. I had to change my system a couple of years ago to address my new dedicated home theatre/music room and after much searching went with an Anthem pre/pro with their ARC multi channel room correction. It works well but is not nearly as flexible as something like Acourate or the now discontinued TacT. Given your interests and tech background, I'm sure you will spend many hours playing with the program! jfo's Profile: http://forums.slimdevices.com/member.php?userid=1135 View this thread: http://forums.slimdevices.com/showthread.php?t=104709 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Well the Transporter is much more like it (100 or ohms via RCA). My DAC1 is 60 ohms via XLR. When I connected my Touch directly to my SCM50s I found it a bit "stunted" at the frequency extremes, compared to the DAC1, though otherwise really rather good. I attributed this to the output impedance since the Touch is generally blameless otherwise, including frequency response of course. FWIW I found out about the output impedance being 800 ohms quite some time later.

Hey guys, as per previous discussions I just posted my experience of Acourate on my blog. Neat program with good functionality and feedback on construction of optimal room correction filters. Does take a bit of know-how but IMO worth it for those with interest in the technical bits and computer audio familiarity. At 286E here in North America, not too expensive IMO and certainly does a heck of a lot more objectively than many more $$$ worth of cables, USB tweaks, and such! http://archimago.blogspot.com/2015/11/measurements-digital-room-correction.html Cheers...

The analogue output of the Touch measures well, I like the harmonic distortion profile (reducing distortion into higher orders, regarded as "musical"). The main weakness is a weak output impedence of 800 ohms meaning it should be used with an active preamp or integrated (not direct to power amps or actives).
