| Best cost no object tube phono I'd probably have in mind to use EMT OFD 15, 25, 65 & JSD with FM Acoustics...to easily take advantage of the EQ curves, as I have many 78s. @mcmprov Do you have cartridges with 78rpm styli as well? The larger stylus makes less noise in the ... | |
| Cons of using main XLR/Balanced outs for subwoofer? @zdw11 Unless the preamp has entirely separate circuitry driving the RCA and XLR outputs, when driving both you will have a lower impedance load on one of the XLR signal pins (pin 2 or 3) than you do on the other. The preamp may make less voltage... | |
| The Lifespan of an LP? The CD is about to turn 40 next year and so far there have been very few reports of CDs failing. ?? I've had a few of them fail for no good reason. I think everyone has- heck, I've bought a couple brand new and found them to be unplayable. If so... | |
| Cons of using main XLR/Balanced outs for subwoofer? Is there any harm in using the main XLR output to send signal to the subwoofers, and using the 1, or 2 RCA output to send signal to the main drivers?Yes. You'll unbalance the signal going to your main amps.The solution is to use a set of special... | |
| 845/211 tube amplifiers with kef reference 5? You should be fine with P/P 845 or 211’s, or even SE ones with the speakers being 90db, and if the amps have a 4ohm tap, and you don’t want to go too loud with the SE’s. The 8ohm tap will give more watts but "could" a problem in the bass. https... | |
| Advise on Long Phono Cable run I do not know if I can rewire it from RCA to XLR plugs. We've done it but its a real pain. You have to take the base of the arm apart; there's a tiny circuit board in its base where the wires from the cartridge are interfaced with the output con... | |
| The Lifespan of an LP? The Library of Congress did a study of archival audio storage in the 1980s. In this study they concluded that laminated media like tape and CDs had lifespans that were measured in years and a couple of decades, depending on storage. Non-laminated ... | |
| 845/211 tube amplifiers with kef reference 5? Bel Canto SET80 use 845R power triodes and output 70Watts per channel. This is why this amp won't work with the KEF:http://www.atma-sphere.com/en/resources-paradigms-in-amplifier-design.htmlThe Bel Canto is a Power Paradigm device; the speaker i... | |
| Bass Vs speaker efficiency @phusis +1 | |
| Power regenerator vs conditioner Maybe newer PS Audio regenerators are much better, I don't know. Anyone compared ?Yes. The new ones seem considerably better. We could not run our gear on the older ones but we can now and they help out!Now those German things look serious and the... | |
| Bass Vs speaker efficiency Is it possible that their reasoning has less to do with cost (they can always pass on the cost) or precision (I’m sure they have the manufacturing prowess to address precision), but maybe they feel that less efficient speakers bring something t... | |
| Other Rectifier tubes Alternative for 5AR4 No. I mean that in your amp that quality won't make a difference. Cathode stripping is a phenomena of indirectly heated power tubes. Your power tubes are directly heated (the filament is the cathode literally) so cathode stripping is impossible. | |
| NOS Tubes - Ecstasy or Agony I wonder if something about the circuit in my preamp is especially sensitive to microphonic tubes.@drewh1 It probably is. If that is the case, you have to handpick the tubes for low microphonics. Its a good idea to specify that to the supplier; if... | |
| Balanced vs Unbalanced? But during my test, I notice that it is not the case. I don’t know if its my system act differently or not. The problem is that your gear doesn't support the balanced line standard, also known as AES48. This means that the interconnect cables will... | |
| 845/211 tube amplifiers with kef reference 5? @thegreenman Unless you are in a small room there is simply now way any SET is going to do that speaker justice and the other way 'round. Don't do it! Your speakers need a bit of power, being rated at 90dB. KEF rates the speaker at 8 ohms, but th... |
