| Target bias dictated by amp or by tube? If one were to use the lower of the two, which means it would be running out of spec according to the amp, does the amp simply produce less power or will the sonic qualities suffer as well?The power will be unaffected. | |
| Capacitors for HP filters in tube amps recommendations? @bdp24 , @pragmasi is giving you good advice. I've had a number of customers do things like this and we've used polystyrenes for the job as there's very little out there that is small enough in any other dielectric. | |
| Top vintage receivers vs. modern high-end equipment I've serviced a bit of vintage gear and one thing I've noticed is that quite often if you really want the solid state stuff to work properly its going to cost a lot to make it happen- often more than tube gear. This is because there are a lot more... | |
| What Class D amps will drive a 2 ohm load A learning point for me from this thread is that it appears there are no standardized measurements for current and damping factor.@dsper This statement is tricky. But you are on to something - they can be misleading. 'Current' is the one that is ... | |
| New Preamp arrived.... Warmup and break-in are essential with any active preamp. You can't take it seriously for the first 20 minutes or so and it really will need an hour or two to sound right (our preamps take about an hour). If its all going well you should hear acro... | |
| Output Impedance and Speaker Impedance @atmasphere - do you think there is a chance to damage the drivers by overdamping them ? They're paper (papyrus if you're so inclined :) The bass when connected to the 4 ohm posts is less pronounced.... maybe another question for AerialNo. Yo... | |
| Coincident speakers 14 Ohms - What amplification to use when streaming Tidal. are there speaker at 107? Probably.Such will be horn-loaded. The Hartstfield loudspeaker, which uses JBL components, is quite respected and is 105dB. | |
| Time to buy a class D amp? As for ecological concerns, at low power levels, where most amps operate during most listening, even class D amps are inefficient.This statement is incorrect. The efficiency of a class D amp is such that at higher power levels its power draw is s... | |
| Atma-Sphere MP-3 Mk. 3.3 vs. VAC CPA-1 MK II or Avatar Super - Recommendations Isn’t the sound directly proportional to the weight of the transformer & tube used?No- that simply has nothing to do with it. Things to look for: a simple signal path, available tubes (some preamps use tubes that are no longer made), whether ... | |
| Best Analog for $10K no it's not because I refered in specific to the exactly and precise RIAA eq, additional I was precsie to post: whole LP playback process that between other things means a second inverse RIAA eq. and all the other " problems " through the analo... | |
| Output Impedance and Speaker Impedance the cone excursion is not halted, but over travels slightly on the out and the inward movement, in other-words it’s not as tightly control as Aerial would like it to be. This is only partially true. A loudspeaker cone can be overdamped; looking ... | |
| Best Analog for $10K R2R does not suffer RIAA Eq. and the lowest bass registers / octaves are in stereo - unlike LP which are in mono. This statement is incorrect. LP bass is mono **only if the bass was out of phase** in the original recording. Out of phase bass can k... | |
| Coincident speakers 14 Ohms - What amplification to use when streaming Tidal. 97 (or even 94) dB sensitivity is VERY efficient. I would characterize 97 as the high end of moderate efficiency and 94 in the median of moderate, with 90 at the bottom. 89dB this at the higher end of low efficiency, and 97-98dB at the lower end o... | |
| Time to buy a class D amp? This is wholly, completely, and utterly false, speculative, and prejudiced not only have some of us "listened' we have also actually "measured" using reliable, repeatable, objective measurement techniques that are recognized by engineers, scien... | |
| Coincident speakers 14 Ohms - What amplification to use when streaming Tidal. My Coincidents are at a 97 db sensitivity, so I don’t think that is inefficient, but what do I know. Seriously, using an 8 Ohm amp on these 14 Ohm speakers will cause what kinds of problems? Yes- at that impedance 97 dB would be a high sensiti... |
