Looking for great tube integrated for Martin Logan Summit X speakers
I have owned a Primaluns Dialouge 1 Intergrated No sorry it’s the other way around. ML’s https://hometheaterhifi.com/wp-content/uploads/2014/12/martin-logan-summit-x-impedance-phase-graph.g...

"George and others, what should I listen for that will show me the limitations of tubes with my speakers? Is there specific music that will make this apparent to me? I want to make sure I grasp the effect of the impedance shortfall of tubes before I listen to the Sanders." smills59- It's great, having the experience/wisdom of SOME qualified members here, but trust your own ears. As mentioned earlier, white papers with graphs and specs certainly are necessary to establish a baseline "good," but it ain't gonna ensure what YOUR ears like. Your favorite music will sound more convincing on one of the two. Happy listening! |
"George and others, what should I listen for that will show me the limitations of tubes with my speakers? As I said above a tube amp that’s a good design, but doing it hard into this load of the Summits. The hard load is at: At 5khz to 20khz may show a distant subdued high frequency. And again at 3.5khz this may soften the presence area of the mids You may "characterize" this as sweet and euphonic at first listen. Then after a while, even a week or two you may understand that it’s not what it should be, and that "the life" is missing from the music, detail, attack, presence and harmonic decay are waning. Saying all this is with a tube amp that behaves itself in the top end. But the Prima Luna has an odd peak up there, that says to me output transformers are ringing (oscillating). This "could" counter to a degree the statements I make above but in a very crude way. https://www.stereophile.com/images/1214PLDPIfig01.jpg Cheers George |
The amp now has about 50 hours of break in and I have listened now for about 15 hours. I have to say, it's still amazing. I'm pretty new at this, but I'm not hearing what George is referring to. Not saying he is incorrect, just that I'm thoroughly enjoying this amp. Break in for this is about 100 hours, so it should be in it's prime Monday night. I have the Sanders and my old Plinius action as preamp ready to power up mid-week. Question: should I plug in the Sanders to let it begin breaking in? Do I have to have speakers attached if it's on?
