| Amps Atma-Sphere M-60 Mono blocks OTL design If in the driver tubes, possibly. If some of the power tubes are blown out in one channel that could do it too.

| When and how did you, if at all, realize vinyl is better? The way I look at it: the ticks and pops (which can be minimized with good phono preamp design, as a poor design will have a lot more ticks and pops) exist in space separate from the music. With digital, the coloration is inherent in the music its... | |
| When and how did you, if at all, realize vinyl is better? There is something therapeutic about analog sound that relaxes me that digital simply lacks. I can't explain it.Dr. Herbert Melcher has shown that the brain has tipping points. Normally music is processed by the limbic centers; this is where toe ... | |
| Impedance matching device The two amps are likely not that different in sound otherwise but the Sumo has more gain.This means the preamp is not working as hard and that's likely the difference you are hearing. | |
| home circuit breaker - good idea or not to increase to higher amp fuse? Its not just the breaker but the wiring as well that would have to be upgraded; doing just the breaker would result in a Fire Hazard. FWIW, a 20 amp circuit is a lot of power for an audio system and should enough, unless you have a really really b... | |
| Amps Atma-Sphere M-60 Mono blocks OTL design As usual, the layout looks meticulous.I assume the front 6SN7 nearest the faceplate still has the most effect when tube rolling? Yes. It seems to sound a lot better too. In particular the phono has more gain and less noise. My workers take a lot o... | |
| Amps Atma-Sphere M-60 Mono blocks OTL design I notice with concern, the MP-1 now uses only two 6SN7's per side instead of five. Hopefully we're not losing any of the good things valves bring to the table. Besides lower noise, what's your thinking Ralph? Cheaper to re-tube? Just kidding! H... | |
| The best coupling caps in power amp ?? Mundorf, Infinicap ?? Just to be clear, the usual handling of a Teflon cap required to install it has not resulting in a change in value in the 20 years we've been using them (prior to using V-Caps we had Teflon caps made for us). So this is far less of an issue than I... | |
| Concurrent use of balanced and unbalanced outputs: Lamm L1 If using a Lamm preamp, there appears to be no advantage to using the XLR outputs as the preamp is only single-ended. If you want to use balanced connections from the preamp I would seek a different preamp. | |
| The best coupling caps in power amp ?? Mundorf, Infinicap ?? No; but if you've handled a Teflon cap, then unless it was hermetically sealed you probably changed its value. You won't see much in the way of physical deformation though. | |
| The best coupling caps in power amp ?? Mundorf, Infinicap ?? We've been auditioning coupling capacitors for close to 40 years now. The current king is the V-Cap copper foil Teflon; it is both neutral and extremely musical.As far as musical goes we've heard some extremely good paper and oil types but the pro... | |

| Tube Watts Vs. Soild-State Watts? The watts are the same.In the end as much as we audiophiles hate to admit it, its all about what distortions exist and how much.Tubes tend to have higher amounts of lower-ordered harmonics (which sound like 'richness' to the human ear). Transistor... | |
| Amps Atma-Sphere M-60 Mono blocks OTL design Where's a good source for Russian and Chinese 6AS7? We stock both and both are available on ebay.Usually when we ship a set of amps we precondition the tubes first and then play them. In this case since the amp was used it came with its own tube... | |
