Class D amps that are superior to all or most?
Ralph,Are you using tubes on the input....or is it discrete solid state or integrated circuits? Have you tried all kinds (types like toroid or enclosed, wire wound or foil...better wire quality, directionality of the wire, cryoing the coils, wheth... 
Class D amps that are superior to all or most?
I can mod your PS Audio 1200 amps to sound way better. The modules are basically stock (they only remove a coupling cap they don’t need because they already have Rel-Cap capacitors after the tube stage and they remove a resistor on the board that ... 
Technics SU-R1000 a new Class-D GaN Technology integrated
Hmmmmm......A Pass preamp (bottom of the line) and last generation Bryston amp......whatever.  Where is the beef?What about The AGD mono Audion's driven by a super balanced passive pre......now that might be meaningful. 
Hoping for a recommendation for stereo amp around $1500 or less ($2k max)
Modded VTV Purifi $999 amp ($1650 with mods).  500 watts into 2 ohms......will sound really great. 
AGD Audion GaN Class D In The House
Tweak 1,How can you say that it is coming to a close when he has promised a shipping date about 7 times and never met it. I do expect the "Waiting for Godot" amp to be released some day.....but already we have had an 18 month wait since you first ... 
Technics SU-R1000 a new Class-D GaN Technology integrated
I am not sour or bitter. Just calling it as I read it. What do you gleem from the reviews so far? I WANT this thing to beat everything. This is why I am not pleased with ALL the reviews, so far. What I read is that it is a great $10K integrated am... 
Technics SU-R1000 a new Class-D GaN Technology integrated
the lbtech review does not even compare the amp to anything except to say it is not as powerful as the Mac or Hegel.....so what does that tell?....nothing.The Spanish review says what?  Most of use don't understand spanish and there seems to be so... 
My new VTV Audio Class D amp arrived today
How would you compare the $979 VTV Purifi amp with the $150 ac mod to other class d amps in the $1500-$2k range with no mods? There is no way that anyone would know this without direct A/Bs.  I have not heard any other stock amp besides the VTV... 
Are there passive attenuators that don't zero volume and only offer one input ?
Here is a balanced attenuator that I just made for someone.....he loves it.http://tweakaudio.com/EVS-2/custom_modsultimate_attenuators.html 
Mytek Empire with GANFET MODULE
Mytek, this summer, is releasing a stereo 200W a channel GaN amp for $6K. The new Manhattan amp.If that is too much then this month the Premium-Audio 200 watt a channel GaN stereo amp will be released for $699. 
"Mytek Empire monoblock power amps, with GaN based technology."
His comment was directly below yours but I believe he is talking about the Technics.....It is a Technics thread and he is a Technics dealer. His website does not list Mytek as one of his product lines. 
"Mytek Empire monoblock power amps, with GaN based technology."
George,I believe he is talking about the new Technics amp......in one of those promo presentations....the guy said it was 1.5 meg. 
"Mytek Empire monoblock power amps, with GaN based technology."
The input impedance on my modded IceEdge amp that I was playing with was 47K after the first mod. I then raised that resistor to 148K and it sounded noticeably better. This was driven by a 50 ohm source that is biased with 10 ma of current on its ... 
"Mytek Empire monoblock power amps, with GaN based technology."
I agree. Passive preamps won’t like that either. The Purifi front end eval board (FE02A) has a 5K impedance per phase....even worse. I change that in my mods to 148K.....mucho better. Designers are trying to squeeze every number. Lower impedance m... 
Should say this and be fair with PS Audio stuff
The happy news is that I am modding IceEdge amps for people (including the PS Audio 1200s). So, my amp is back! Yes, I mod Purifi based amps too.
