Class A into Class AB
Would you call that a class A amp or a class AB amp? @kren0006 By definition, that's a class AB amplifier. The rest is all marketing.    
Changing Turntable to Balanced Output
@audiosaurusrex I don't see anything there that has anything to do with the phono section.  
Class A into Class AB
Any way you look at it the amp is considered a class AB amp. All AB means is that at some lower power the amp is class A, transitioning to B operation above that lower power value. 'B' means that one of the output devices is no longer conducting. ... 
Grounding cable gauge size
That’s what I think. Do you think 16-gauge silver to be ok? Of course! Like I said, if the wire really has to take any current you have much bigger fish to fry due to some sort of Bad Thing going on with a component or AC outlet miswired. When ... 
Changing Turntable to Balanced Output
balanced shmalanced..........unless all your components are differentially balanced, you will not get the improved performance. This statement is false. The Ampex 351 tube tape electronics were used to record a great deal of classical and jazz ... 
Opinions on Pure Audio Project Quintet 15 Horn 1 Please
That was my take on the Spatial Audio X3. The midrange wasn’t fleshed out and “real “ to my ears. @jjss49  That speaker can be quite revealing. What amplifier were you using? If you have the room to set up open baffle speakers the soundstage ... 
SET Shootout China VS The USA
my fav pre tubes are AX, AU, but honestly thats not based on exp, as i’ve not heard a 6SN7 series type pre tubes. I have no idea how they perform. Once you hear what they do there’s no going back. If your SETs don't use 6SN7s there's a whole be... 
Grounding cable gauge size
There's no current in the wire unless something is terribly wrong. So a light gauge is no worries.  
Class-D amps - a different re view
Zombie thread come to eat your brains!!   A lot has happened in the last 14 years...  
SET Shootout China VS The USA
I take it you have a 12AT7 LTP @ +-300V with something like a cascode 10M45S CCS below? @pesky_wabbit Yes, something very similar to that although the CCS is our own design. There's a 'steering diode' so the cathode voltage can't fall below -0.... 
Anybody use a single ended component with one that is balanced?
@steakster If you are talking about at the input of the amp, I think so.  
AGD Audio Mk2 review
When are you going to have production of your GaN mono blocks and when will they be added to your website and when will they get a formal review? How many proto types are out there? The only comment on the sound seems to be from June of this year... 
Does a cartridge that has been in storage for an extended period need play time…
The cartridge cantilever suspension is subject to perishing over time and it makes no difference if stored or played. Sometimes it gets harder and less flexible, sometimes it turns to a soft goo and the cantilever all but collapses. Different mat... 
AGD Audio Mk2 review
Yes, there are now class D amps that challenge the best tube amps on their own turf!  
SET Shootout China VS The USA
They just have come to learn that you have to listen to an audio product to really know if it’s for you. People realize there is no better way to select these products. Yes- heaven forbid that audio companies actually publish spec sheets that t...
