Looking for great tube integrated for Martin Logan Summit X speakers


I've had upgrade fever every since I added bass traps and acoustic panels to my listening room and wondered why I didn't do that years ago.  So I've decided to change my Plinius Hautonga integrated and make the plunge to tubes. I want that sound, and the thought of tube rolling appeals to me.  I was leaning toward the Primaluna Dialogue HP integrated, but after doing more reading, I'm concerned that it won't have adequate power due to the Summit's impedance needs.  I'm admittedly a novice with tubes, so seeking help from the forum.   My room is about 12x15, with the area behind my listening position open for an additional eight feet.  I don't listen at high volumes at all, and my favorite music is female jazz, smooth jazz, Nora Jones type vocals.  Music comes from SACDs and Tidal exclusively - I have no analogue gear.

The rest of my gear:
  • Gustard x20u DAC modified by Rick Schultz
  • Oppo 103D for SACDs modified by Rick Schultz
  • Bryston BDP-1 music streamer
Will I be happy with the Primaluna, or do you have other suggestions in the $5,000 range?  Or should I stay away from tubes for these speakers?

Appreciate your opinions!

I've had my PL HP for 4 years. 

ML stats have been on my radar among many others.

I found them to sound fantastic with the PL.

Using sealed floorstanders/sub, and just looking for something different.

IMO, a subjective decision that only your ears can decide.

You won't know until any speaker is in your room.

This review mentions tube/SS performance with the Summit X

If more power is needed, you could drop KT120 or 150's to replace the EL34's. Other than visceral DEEP bass, I didn't hear anything lacking with the EL34's. Subs would take care of this.
This is just my personal taste, someone else may find it okay without a sub. 
Should be an interesting shootout.

Technical specs/graphs may indicate absolutes, but it won't guarantee what your ears like.

The PL certainly will equal, if not best the Sanders in build quality/detail.

"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."

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!


"Not sure I would put another $800 into the PL, but KT120s might be possible. Any suggestions? Or is it better to replace the two gain tubes fIrst? "

Experimenting with the 2 inner gain tubes can fine tune the overall characteristics of whatever power tubes are in the amp.
The EL34’s have great mids and highs. You might hear the KT88,120 as more solid in the bass, but less refined mids. The KT150’s are reported to have the best of the EL34 mids and KT88’s low end.

I had a feeling you would be pleased with the performance of the ML’s/PL. I have a PL HP, and thought ML’s sound great thru it.

As mentioned earlier, your own ears are the best judge.

Still wondering what your impressions are of the Sanders, compared to the PL. I’m guessing the Sanders may subjectively, catch your attention in some areas, but wont sound as organic as the PL. That of course, is just my subjective opinion. You may prefer the Sanders.
"crackle"

Perhaps. imperfection of the recording. Just as you may hear exaggerated "S"
in others?

I notice this occasionally in my system. I have confirmed it being the recording, by playing suspect record at a show/dealer, at it’s heard on the "$$$SYSTEM"

The best systems seem to only distract you because of everything else being so good.

I’ve heard plenty of speakers with the PL.
ML’s to me,sound amazing to me. Same goes for horns, also many of the
usual suspects talked about here. It’s really a personal preference, since the PL will mate with just about every speaker on the market.

Notice I didn’t write ALL.

If you keep the PL, fine tuning is achieved thru the inner gain tubes, power tubes and power cable. The power cable thing is yet another contentious subject which
starts wars here.

smills59,

Enjoy you're new setup. As you found  out for yourself,  the knowledge/wisdom of the forums is valuable,  yet it doesn't replace what your ears ultimately prefer.

If your space allows it, speaker placement /room treatment will optimize their performance further.

Happy listening!
