"This Latest Digital Amp Is Great "
Well, Vince........I have built amps using several of the new self-oscillating amps modules. I have also heard some of the competing brands using the same modules.Maybe because I have spent 20+ years trying to build conventional amps, that I am mo... 
Best wire to replace stock wiring in preamp?
Anyone interested in reading some rather technical details on the inner workings of modern DACs, I have some info that I can share.A buddy in the chip testing business was able to answer some questions that the TI marketing weenie would not, or co...

Well, excuse me........I got the delta and the sigma reversed. I suppose that I am the first (old twit) to do that.Sigma-delta. There, are you happy now?One bit is a "sigma-delta"........you sum (sigma) up a bunch of little steps (delta) to make one.

"Exemplary restraint". Agreed.Mind you, having built many of these new "digital" amps, the ones based on a certain platform are more load dependent than I would like. I would caution anyone who is disappointed by them to give them another listen o...

I have never worked, or will, for TI. Matter of fact, I hate them. I make obscene gestures at their plant quite often. I know someone out in AZ who hates them as much as I do. One day, he told his new bosses that when he worked for H-P, that we we...

You said that all Burr-Brown DAC are as bright as a screaming witch, not me. That implies that most of our CD players screech.Drive down to Texas, and I'll force you to listen to one.I am not going to tell you where the (several hundred) other one... 
Best wire to replace stock wiring in preamp?
How can you determine by reading some review that the output transients are too high? Delta-sigma and R-2R ladder DACs are nowhere near alike in their topology or implementation. One outputs a differential voltage, which needs to be summed and low...

I don't buy any of that. If they sound horrible, then it is because of a poor design. ANY DAC will sound horrible is used the wrong way.There is not one designer that I know of that would prefer to use a delta-sigma DAC (of any model) over a R-2R ...

And just why do you think that B-B DACs "are as bright as a screaming witch"? Perhaps you would care to share this with us, as well as your design experience and insight.Reason being........I don't buy what you are selling. 
The most emotional amp out there?
Yeah......I recall Cold Bear. Just don't ask why.No, I never touched it, but the story that goes with it.......Pat 
The most emotional amp out there?
Why is an amp supposed to be "emotional"? I thought the goal of us amp makers was to produce a product that neither added to, subtracted from, or changed the original source.Right????Pat 
amp transformer hum through speakers ?
I know someone who had a Tice power conditioner radiating so much that it induced hum into the woofer voice coil.But that was a very unusual problem. If the amp transformer radiates that much, then that indicates a problem with it. There is an eas... 
Can you have too many tubes?
Only 200??? I bet if you added up all the ones in the studio........and that big trunk that you have.......(Albert has a trunk of output tubes, sorted as to how each sounds, and can be swapped out depending on source material.).......it would add ... 
Just a power amp, turntable and speakers?
Are you sure that it is pre-amp out, and not just a tape out, which will not have volume control. 
Boulder amps v,s Levinson amps
One of my customers in Atlanta has a lot of experience with Boulder amps. He reports that they are very dynamic, with clean bass. I'll try to get detailed info on the one in question from him next time we talk. FWIIW, he is not fond of their pream...
