Handling Heavy Amps
My dilemma now is that while I really enjoyed this sound presentation it wasn’t significantly better to my ears than the Bryston that would justify twice the price  So I will struggle with this decision  If it was around $9 or $10k instead of $14... 
Handling Heavy Amps
@cundare2 If you don't mind some correction, the 3rd harmonic isn't 'nasty'. Musically its an octave and a 5th above the fundamental tone. Its well-known that it is innocuous such that this fact is often only mentioned in passing in engineering to... 
300b lovers
Ralph, I see you introduced a PP 300B amplifier at one of the recent hifi shows. How do you think it compares to your Class D amplifier, in subjective terms? The prototypes at the show sound very similar to our class D amps; the big difference ... 
Handling Heavy Amps
Technical papers that discuss Class D topology suggest that the distortion resulting from the topology’s dead-time constraints is similar in effect to what we used to call TIM or SID distortion in high-feedback, low slew-rate designs. @cundare2... 
Excellent Solid State or Hybrid Monoblocks Recommendations
I was talking about pairing the Atmasphere class D amps with the Wilson Alexx V @carey1110 They should be fine with the Alexx's from all the reports we have.  
Handling Heavy Amps
 The one area where I think they differ the most with the Pass amps I've had is I think their high fequencies are a little more recessed,with less sparkle.  @ddafoe The class D goes beyond human hearing so that's not a frequency response thing....

The Raven is not very sensitive to loads. In practice, power amps range from 10K (typical solid-state) to as high as 470K for a handful of vintage tube amps. Most modern tube amps are 100K. Plus whatever cable capacitance is there, along with the... 
This One has Me Stumped
If you make a change and that breaks whatever you made the change in, that's a pretty good sign that the change introduced the problem. I think Pass will figure it out.  
How important is the efficiency of a speaker to you?
You’re referring to a boutique element of high efficiency drivers that aren’t representative of this segment. Low eff. drivers have their expensive iterations as well, and when you count in the typically larger size of high eff. drivers, bigger v...

Pin 1 is shield and grounded to chassis, pin 2 is XLR + phase and pin 3 is XLR - phase.  It will drive any power amp with XLR connections, and will happily drive a 10K amp input impedance. @donsachs How do you deal with the variable loads which... 
How important is the efficiency of a speaker to you?
@lonemountain You are inferring something I did not say with this statement:    The idea that lower efficiency is always done as a cost saving excercise is clearly not true.    I don't need to repeat myself here. But it may interest you to kno... 
Preamp power supply capacitor upgrade
@yowser Your goal here is, I assume, to improve performance. To that end, by bypassing the power supply, what you want is uniform output impedance of the power supply at all frequencies. So the correct dielectric may not be the one that is also ... 
How important is the efficiency of a speaker to you?
Dependency and "seems to be" - as a technical observation I don't see how it holds an absolute correlation with regard the sonic outcome of SS amps in each and every case and high efficiency speaker combination, and to which degree? @phusis Ris... 
How important is the efficiency of a speaker to you?
 That the idea that dynamic range is improved or noise floor is changed due to speaker efficiency alone is simply not true?   @lonemountain  In a word, No. The physics of how voice coils work is the problem. While there may be examples that s... 
How important is the efficiency of a speaker to you?
Nothing sterile, tonally lean, mechanical or bright sounding about the Brit, I can tell you that, or whatever you’re implying about high power amps sonics. @phusis The issue is that most amps made using feedback, which includes high power solid...
