| Are all amps being built wrong? Ralph, thanks for the info. I recall that many years ago you explained that global NF creates temporal intermodular (TIM) distortion because of the infinitesimally small amount of time that it takes for the signal (after phase inversion) to lo... | |
| SET the best? So this is a mono set? I assume you recommend your tube pre, or is that coming soon too? @bjesien We've been making preamps since 1989- the MP-1 was the first balanced line preamp made for home audio.Intrigued. Could you please point me in the dir... | |
| Are most tube preamps ‘ultra linear’? Single ended amps are not so obviously the purest thing around. They are low power with lots of second order harmonic distortion. They react with reactive speaker loads so their output is not flat. And they are non-linear. They compress the neg... | |
| Are Quicksilver power tube amps in the same league as VAC, VTL, BAT, ARC, ...? It appears that I can't be wrong with QS monoblocks and I need to get at least 100 WPC amps.@iYes you can go wrong but not due to the quality. Again, unless you are nearfield or in a smaller room, 100 watts on a speaker that's only 87dB in an aver... | |
| Are Quicksilver power tube amps in the same league as VAC, VTL, BAT, ARC, ...? I need to drive 87dB speaker, so the power has to be at least 80Watts.Unless you are nearfield or have a smaller room, you'll need more power than that! But to your OP question: 'Yes'. | |
| Thoughts on moving from a 1200G to Sota Saphire or above 2. Dynamics: Everything sounded smaller and controlled in 1200G compared to the other TTs. The explosive dynamics were missing. The SP10mk2 was better. The idlers were simply in a different league. My previous TT was a Platine Verdier and that ... | |
| Are all amps being built wrong? Does that type of feedback create the same distortion as the type of NF used in solid state amps or is the distortion still there but tamed to some extent? @bifwynne It does not seem to but I've not done a lot of research on the topic. But... | |
| SET the best? When is yours coming out and what’s the price point?@bjesien We're doing limited production right now. They are $5200/pair. I've not heard the SPEC amp. But I have heard class D amps that are boring; I know what you're talking about. There's as mu... | |
| SET the best? There might be a revolution in the making…There is. Its now possible to make class D amps that are just as smooth as the best tube amps (whatever you have in mind what that might be) and even more detailed (owing to lower distortion). | |
| You own a store, you sell 2 brands, which? Why not Panasonic, then you get the Technics line too. And also Harmon Kardon, since you get JBL with that... | |
| SET the best? I mean at 8 oclock, the SPL would be over whleming.SETs generate up to 10%THD at full power. If you have a lower powered SET on a speaker of insufficient efficiency, the result will be a lot of distortion, which the ear translates as 'loudness'. B... | |
| Are all amps being built wrong? Speaker drivers are designed to work best when fed with a voltage source.I wish it were this simple. The problem has been that the technology hasn't been up to the theory. To get a tube amplifier to behave as a voltage source you need feedback. Bu... | |
| cassettes CAN sound better than vinyl. You can get the top end of a cassette to sound pretty good but there is not enough tape width to get all the low frequency stuff.@russ69 Actually its the tape speed that says what the bass will do, coupled with how much gain the tape head preamp... | |
| Low-sensitivity speakers — What's special about them? I prefer low sensitivity speakers. Mine are listed at 91,@arcticdeth 91dB isn't low sensitivity. Its more of a medium sensitivity.To put this in perspective, the low eighties is near-criminal inefficiency (its very hard to find an amp that sounds... | |
| Leaky capacitors need replacement? All is well except the bias won't zero down and there seems to be a low hum over speakers at idle which I don't think was there before. Those caps may not be the only ones that were bad. But your tubes can cause both hum and bias problems- have t... |
