any thoughts on the pioneer sx-939 receiver
Get the filter caps replaced! Also there are a fair number of tantalum electrolytics in the signal path and they can be tricky to chase down if they are failing. It was a mistake to put them in in the first place, no time like the present if you g... 
Amp choices for Silverline Sonata
I know our amps work great on the Sonatas. In general, the speakers are very tube friendly and you will get your best results with a good tube amp. Spend the time- it will be worth it. 
CLASS A AMPLIFIERS
Calanctus, Your speakers are a good example of what I was talking about. ESLs in general, regardless of their particular impedance curve, want to see the same power for a given sound pressure regardless of what their impedance is at a particular f... 
CLASS A AMPLIFIERS
Unsound, just so you know, Class A has nothing to do with push-pull vs single-ended. Also, a Class A amplifier's peak power will always be the same as its continuous power, IOW the 'headroom' rating will be 0db. An amp that has more that 0db headr... 
CLASS A AMPLIFIERS
Class A amplifiers nearly always exhibit more authority, but this has nothing to do with power. I should point out that a Class A amplifier can be either push-pull, single-ended, tube or transistor. What is important is that the amplifying device ... 
Powerful Push Pull Triode Amplifiers
-Since triodes were mentioned- we make a 500 watt triode amp:http://www.atma-sphere.com/products/ma3.html 
Burned out hi fi salesman
I have a further 2 cents to add- 90% of what's out there really does not sound 5% different than its bretheren. However the remaining 5% can sound *so* much better that non-audiophiles from off the street can hear the improvement.Sounds to me like... 
rca and xlr inputs connected simultaneously?
Unclejeff is incorrect here. Usually in a balanced amplifier the RCA corresponds to either pin one or pin three of the XLR.The real issue is that the loading from the two sources will interfere with each other and the sound will be less than optim... 
Tube or SS for Vocals/Strings
"No brainer - Tubes." Triodes- smooth with detail and consistant over time.

Tube amp warm up
A lot of warmup character has to do with the tubes themselves, as well as filter capacitors. As most of you might know, we don't have any transformers in our amps, and our MP-1 MkIII is entirely regulated, yet the warmup character on any of these ... 
CD Player creating white noise through preamp.
Sure! A CD player can emit digital noise which is audible. Sometimes it will sound like an odd buzzing, but can manifest as a hiss too. Viewing the output with an oscilloscpe can reveal what is going on. If the noise is profound it might be a malf... 
A tubes vs. Solid State question.
Hi Nrchy, even ordered harmonics are harmonics where the fundamental frequency has been multiplied by an even number, 2,4 and the like. 'Times 2' yields the '2nd harmonic' and so on. Odd orders are fundamentals multiplied by odd numbers, 3,5 and s... 
A tubes vs. Solid State question.
It surprises me that at this late date, this debate can still go on. I remember in an analog/digital debate years ago someone mentioning warped records as a reason to throw out all analog forever. It was a sideline comment- obviously just because ... 
A tubes vs. Solid State question.
If the amplifier is push-pull, then such harmonics can be cancelled in the output. This is how transistors do it too. Single-ended triode amplifiers thus have much more even-ordered harmonic coloration, which is the source of their (IMO) overly-ri...
