| Solid state amp that tube fan can be happy with? And my line stage has RCA outputs so prefer not to need adaptors for balanced amp inputs. I'll repeat, I have reasons for a stereo amp so no mono blocs considered. Also I don't expect SS to sound just like tubes, but I'd like a bit of sonic war... | |
| Damping Factor and Overall Negative Feedback. I’ve read you say that you’ve built zero feedback amps for decades. Are your latest Class D amp zero feedback also? I am a Vandersteen owner, looking at new possible zero feedback amps @patrickdowns No, our class D amps run a lot of feedback. We ... | |
| What contributes most to a change in how an amplifier sounds? @emergingsoul The secondary thing is the distortion signature of the amp, which audiophiles call the 'sonic' signature. This is in turn caused by something called the 'transfer characteristic' of the amp. The transfer characteristic has something ... | |
| What's the best 6NS7 tube you have tried in your Atma-Sphere MP-3 preamp? The best 6SN7 we've heard so far is the Linlai. There is a globe variant that I don't think will work as well- the globe resonates easily! Of the NOS tubes the KenRad gets the highest marks. The 12AU7 should not be ignored- it has the bigger eff... | |
| Solid state amp that tube fan can be happy with? @pryso There are class D amps now that are smooth and detailed through the mids and highs like an excellent tube amplifier- so much that its hard to go back to tubes. | |
| Amp search A crossover to match levels? Don't think I understand. As long as gain on both amps is the same, the levels will also be the same. There’s nothing wrong the my current amp btw. @lukaszwk It may not be as simple as that. Plan B is to get a passi... | |
| Please talk me out of buying the Avalon Eclipse @celo unless you have really top notch electronics with a lot of power, you may well have dodged a bullet on that one. | |
| Faint buzz in speakers In fact, it is so faint you have to place your ear right up against the cone to hear it. @jmfinney As @yoyoyaya and @herman have pointed out, there's nothing wrong with the amp. With most speakers and most amps, if you put your ear against the ... | |
| Recommendation for ATC SCM150 Amp/Pre One of the engineers at ATC was an intern with us, when he left it was to go to California to work at ATC. @ei001h If you get the active version, it has a balanced input that conforms to the balanced standard, AES48. A lot of high end audio balan... | |
| Please talk me out of buying the Avalon Eclipse @celo , those speakers need a lot of power (+150 Watts) and it should be clean power. They can play deep bass, but from all the feedback we have on that speaker, you need just the right amp to do it. | |
| Any US manufacturer of a 845 SET amplifier This causes me pause as my 93db/6ohm speakers might be on the edge. @decooney You are correct. In most rooms with speakers of that efficiency you’ll want more like 50 to 100 Watts. SETs, if zero feedback (and most are), have only about 20-25% u... | |
| Amp search @lukaszwk 32 dB is the problem. The less power an amp has, the more likely the gain will be less too, since its more likely to be used on more sensitive speakers. So amps of the power level in which you are interested are more likely to have 22-... | |
| Recommendations for a jazz record which demonstrates vinyl superiority over digital --my darTZeel 468 mono blocks have a ’peak watt’ output (the value holds for 8 seconds after) read out on the front face. it’s very easy to see with your eyes how all analog vinyl has higher peaks than digital with the same recording played back ... | |
| I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode I wonder if the output transformer of amplifier with the triode/UL option is optimized equally for both modes, or if the default is to design for best operation in UL, then simply switch the screens to pair with the plates of the output tubes (us... | |
| After 20 years, in the market for a power amp Sandy Gross the designer of the speakers used a tube amp in his personal system. They sounded fantastic with tubes. Sandy is a customer of ours. The Khartago, while wholly competent, has long since since been bypassed by the rest of my gear.... |
