SET the best?
I want to add vintage speakers to the list, like: Altecs - VOT A5 A7, 19, Valencia, 604. Old Tannoy - Silver, Red. Old JBL L200. Used full range: Lowther, Klangfilm, Telefunken.   New full range drivers like: Audio Nirvana, Lowther, Fostex,...

Hi @ron1264 , I'm not an expertise in Class D amplifiers. But all of them digital and PWM are very different from SET. For example, most of SET fans use high sensitive speakers like: horns or full range drivers. And they like these speakers not...

As ASIC chip designer I can add. For any chip production you need to produce millions of chips of this particular model. Otherwise you will lose a lot of money. For example, companies like Chord who made FPGA based DACs use FPGA for their custom D... 
SET the best?
For me looks very weird that someone who was SET fan suddenly became digital amplifier fan. I can't say that SET are better or worth than digital amplifiers. But they are so different. These amplifiers topologies work best for completely different... 
Top resistors
I built n-1500 crossover for Altec 604E. DIY Altec N1500A (audioheritage.org) I use constant resistors instead of potentiometers 36 Ohm and 7.5 Ohm. I also use resistors 1.2 Ohm - 1.8 Ohm for super tweeter crossover. I tried Duelund Regular and... 
Horn speakers are really bright?

SET roll off highs ? My SET has bandwidth -3db from 7 Hertz to 95K Hertz.

I'am agreed it is not good idea to use full range speakers in parallel with tweeter. Tweeters shouldn't play anything below 10KHz. That is the reason why most of famous producers like JBL, Harbeth, Tannoy use super tweeters with 3rd order high f... 
Horn speakers are really bright?
Hi @unreceivedogma, I use Altec 604E with original and Werner Jagusch crossovers.  The horn of 604E compression driver has an issue - ringing on 7.5KHz. Mastering Labs crossover filter out this frequency. It also suppresses upper bass and lower...

My friend who a DIY speakers builder come to conclusion that compression drivers with metal diaphragms are so transparent and detailed and it shows imperfection of electronics.One example from my experience, when I just bought 300B amplifier I use... 
Acoustic Sounds Series
My experience with the Acoustic Sound Series.Despite sound not bad, most of titles have some grain. I don't know what is it the problemmastering equipment or the conditions of master tapes?The best  Acoustic Sound Series sounding title is Getz/Gi...
