Most Musical 6NS7 tube for a Preamp?
The 6SN7 is in my opinion the best tube for a line section in a preamp. Back when we started using them the tube was considered obsolete and no-one used them at all. Obviously that’s changed in the last 30 years!The Pass Labs XA25 only has single-...

built-in phono stages -- good idea?
This would bring the following benefits to its performance:Elimination of the sensitive and susceptible phono cableReduction of the need for a balanced phono stage Reduction of noise without the need for balanced design -- half of the battle is wo... 
Very basic subwoofer question
In my bedroom system I don't have a lot of room and some recordings have bass that my tiny speakers simply don't even hint at.So I added a sub (Golden Ear Subx). I really had to fiddle with placement so I could hear the bass from my bed. A standin...

High Output Preamp for First Watt SIT-3?
Do you believe the S.I.T.3 would improve SQ further if driving a 12 or 16 ohm speaker load (due to lower distortion) or is 8 ohms optimal for this particular amplifier?If the amplifier begins making a greater percentage of higher ordered harmoni... 
Is there such a thing as too much power?
You can never have too much power. Full stop.This statement is only true in theory.  In the real world where we all live, there are practical considerations that cause this statement to be false.Apparently there is a need to explain why as I see a... 
Recommended SET amp and speakers to 20k
Getting hifi bandwidth out of an SET is challenging when the full power is over about 8 watts or so. Usually the bass is sacrificed so that the output transformer can make it to 20KHz. Often that works, since the speakers that have the sort of eff... 
Time for the Dynaco to go, Affordable Integrated or Separates for Wilson's Under $2.5K?
To refurbish the MkIIIs:Get the filter caps replaced. Replace the bias rectifier. Check the resistors- replace any out of spec. Check the tubes and replace as needed. if you want, get some good coupling caps- stay away from paper and oil caps  as ... 
High Output Preamp for First Watt SIT-3?
@murphbass  **All** amps make lower distortion into higher impedances. You can see this in their specs. You might think the difference to be 'negligible' but the distortion components involved are higher ordered harmonics. Since the ear uses these... 
Is there such a thing as too much power?
Ya, there's a reason Nelson calls his stuff "First Watt". It applies to both tubes and transistors. 
High Output Preamp for First Watt SIT-3?
I think I'll listen to the sentiment of most of the contributors to this thread and build around the better of the two variables: my amp. I like the idea of having a high efficiency speaker on hand when I add an SET amp. Since it's hard to de... 
Is there such a thing as too much power?
I can think of plenty of reasons why a 70 watt amp can sound better than a 300 watt amp. This should come as no surprise whatsoever! 
Discussion of Class D Amps Application & Experiences
Because of their high frq noise, Class D amps can be a problem for tweeters with wide band frequency response and high frequency break up. Excess energy (not music related) can cause the breakup to induce distortion. This statement is entirely ... 
Better amp or better tubes?
all tubes have been purchased with the last 2 years with moderate use. I think they should be fine@emil  The age of the tubes and how much use they've had has nothing to do with whether they are good or not. I've bought plenty of bad tubes that we...
