| Thomas Mayer preamps - the 6AH4 vs the more expensive 10Y I have not heard his products. But I DIY tube preamps and amps using very similar circuit and components. In Thomas Mayer’s circuit, 10Y would be better than 6AH4, with a sound that’s more transparent and dynamic (btw this is the difference betwe... | |
| Need speaker advice If you look at FM2’s spec, the only thing that seems SET friendly is its high impedance (over 8ohm). But it turns out that, I enjoy them better when pairing them with my 2A3 vs. XA25. FM2s were made at least three decades ago- there may be new boo... | |
| Need speaker advice I love SET too, and have used SETs that produce from 1 to 14 watts output. I have a pair of Tannoy Cheviot - so I understand your feeling of Tannoy Eaton :-)What I use now is a pair of Sonus Faber FM2 speakers with a 2A3 SET (3watt output) - the s... | |
| Omega single driver speakers I didn’t go to the single drive speaker route at the end. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. My speakers are 93db sensitive (1w/1m) with 8 ohm impedance (7ohm min).With a listening distance of 8 feet, it seems 15w will be more than enough to produce 100db or so loudness that Symphonic music peaks into from time to time.Assuming 100db is m... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @almarg Thanks again for your thorough explanation. As a big fan of SET amps, I am delighted to hear your experience of XA25. Should I ever endeavor into the ss world, it seems that XA25 would be the natural candidate to try out. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @almarg Many Thanks!In your case, both your VAC and Pass amps are capable of producing 32w I presume. What gave XA25 an edge over the VAC amp with your speakers? Does XA25 have less distortion due to its class A operation in the first 25 watt? | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. A couple tech questions for Roger. Others please chime in too.Is it possible to estimate how much amp power will be enough (i.e. never clipping) simply based on speaker specs (assuming they are correct), and listening habit/situation (i.e. distanc... | |
| Omega single driver speakers Thanks both for the feedback.Would you charaterize Omega sound as forward or recessed (as if the singer/performer is behind the line of speakers)? |
