Kudos to speed controllers
Motor control units do substantially improve the sound of tables, though probably NOT because of more accurate long term speed control (what is measured with the strobe). The motor on the Basis table is an AC motor. It's speed is is determined by ... 
Influence of stylus shapes on distortion
Headsnappin,Often, it is a big factor, particularly with used records. When records are played and damaged by a stylus, that damage tends to be located at a certain depth of groove. Another stylus that rides at a different height may avoid the dam... 
the tough question: Which preamplifier? and why
I have found that the LEAST predictable interaction is between preamp/linestage and an amplifier. A lot of times, a combination that I think will work well does not do so at all. This is a must experiment situation. Tube preamp/linestages, in part... 
Influence of stylus shapes on distortion
It might be just the case that, in more recent times, I've become more picky with setup. However, I do have the impression that cartridges with fine line profiles are extremely sensitive to VTA change. I have seen the charts that show that even fa... 
SET vs OTL
Paul,The pushpull 45 amps were built by a Russian guy named Pavel and were sold through a Washington, D.C. area dealership (Deja Vu Audio). These amps used Acrosound TO-330 output transformers (the feedback taps not employed, obviously). The wirin... 
SET vs OTL
Although I am one of those that expressed a personal preference for 45s and 2a3s over 300bs (I own a pushpull 45 amp and a parallel SET 2a3 amp), I hardly think it is fair to say someone is wrong or inexperienced for have a contrary preference. A ... 
The correct internal-inductance of Windfeld cart.?
Axel,I originally misinterpreted what you were saying about "free" voltage multiplication.What is interesting about your experience with primary loading of the PW cartridge is that your ideal loading (the reflected load seen by the cartridge) is r... 
The correct internal-inductance of Windfeld cart.?
I admit I haven't read through all of these posts, so I am not clear as to the controversy here, but, I don't get the concept of "20 time the voltage for free." The cartridge's output is fixed -- it is a certain amount of mv per the particular mod... 
shorten NBS AC cable
I suppose it has to do with the design/build of particular cables. With something like the Shunyata, the insulation includes material that absorbs stray radiation of RFI (the way ferrite beads do the same), so shortening the cable will reduce the ... 
SET vs OTL
Thanks Atmasphere for clearing up the issue of safety/reliability of direct coupled. A friend has direct coupled OTLs hooked up to Sonus Faber Stradivari speakers. When asked about what might happen if a tube shorted, he just shrugged his shoulder... 
SET vs OTL
Atmasphere,I agree that multiple output tubes is really only a theoretical source of less than perfect sound (my SET has parallel output tubes). I am merely pointing out that "theoretical" concerns can be raised about any design choice.A friend of... 
SET vs OTL
Aarif,I don't think there really is any standard for "neutrality," or any other subjective quality. What I would consider neutral (neutral what? -- high frequencies, low frequency, etc.?). I am not familiar with the Audiovalve RKV that you like, s... 
SET vs OTL
Sns,I actually do like a number of 845 and 211 SET amps. For speakers needing more power than what a low-powered SET can provide, good SETs using either tube are contenders. But, when driving extremely efficient speakers, I don't think they are, a... 
Preamp tubes or amp tubes will give more change?
Nsgarch,That is a terrific, detailed, answer. I believe the Cronus is an integrated amp, so we agree that the small signal tubes come first. I would add to what you say that a particular tube may work better in one place than another -- if the amp... 
SET vs OTL
I like both SET and OTL amps. Both kinds of amps can deliver very clear sound and very good, natural dynamics. OTLs, in particular, sound extremely lively and dynamic.OTLs can be easily scaled up in power by adding more output tubes, though heat a...
