PrimaLuna Prologue 1 or 2?


To anyone with an informed opinion (which obviously includes Kevin Deal if he sees this):

I'm considering a PrimaLuna Prologue 1 or 2 for my system. I've read various descriptions of the sound qualities of each, at least with their stock tubes, but I'm having some difficulty in translating that info into what I'm likely to hear with the equipment I've got. So here it is:

Sources: VPI Scout/Sumiko BPS; modified Sony SACD; Rega Planet 2000 with ModWright Channel Islands DAC
Speakers: Meadowlark Kestrel 2; Hsu Research VTF2MkII
Room: 15'x18'x8'-8"
Music: pop, rock, jazz, vocals, classical, acoustic (folk/bluegrass)

If it makes any difference, I'm coming from a B&K ST-140 and Adcom GFP-710.

Thanks!

Craig, I'm not familar with your system or what in reproduced music is important to you, however I am quite familar with the Primaluna. Its simple - if your into audio because you want to hear every thing crisp and defined so you can listen to all of the nuances of audiophilia you need the 2 as it provides more resolution and detail than the 1, as well as flexibility. If you are into music more and just want to relax and listen to a tune without worrying about what your system is doing the 1 is ideal. IMHO it is the more balanced, tonally speaking, of the two units but you will find the bass a bit less resolved and the highs are a tad softer. Good luck with your choice.
The circuit I expect. I have other amps which use EL34's from which to form my opinions apart from the Primaluna, and my experience with the 1 and those amps with the EL34's is similar except that my other amps have big trannies and produce a tighter bass, but not necessarily deeper bass.

Surprisingly the bass response in the 1 w/EL34's sounds fuller (some might say warmer/looser) throughout the bass frequencies than using the 2 (or in my case the 5) with even the KT88's or 6550's. With these two tube types the bass takes on a different texture, becomes more taut, drum whacks more percussive, its still very capable, and certainly more audiophile approved, etc, but when you plug EL34's (or 6L6's) into the 2 the deep bass become enemic when compared to the 1 or the 2 w/KT88's/6550's.

An important consideration is selecting tube type in the 2 would be the bass capabilities of the speakers. If they don't do deep bass and you want a more crisp tone the 2 would be great, and its really responsive to tailoring with different tube types and brands.

But I'm really sincere in my comments about the 1. I love it for what it is, a great little unit with which you can listen to tunes and forget audiophilia. :-)
Craig, Unless you spring for the PL3 and PL7 go with the the PL2, at least based on my experience with the PL5 that's what I would do. Read the review of 6moons. I think he's pretty spot on on the combo. I've had conversations with Kevin Deal about the differences between the 5 6 and 7. All I've ever been able to get out of him is the curcuit differences between the unit's. No comments whatsever about the sound. For myself, if I was so inclined, I'd wait to read some independent reviews and user reviews on the 7's. I read the review on the PL6 in TAS and learned nothing useful.
Craig, Your question to Rarl re power v pre, is sort of a chicken/egg question and you'll get many folks taking up both positions. For folks just coming to 'tubes' the pre-amp is usually the best choice if only for the reason that its easier to maintain and integrate into your system. Tube amps are a whole different ball of wax, they do require some maintanence and if poorly chosen can be a PITA. But if you buy a tube pre and like it, you'll eventually get a tube amp. Then your hooked!

Apart from the principal benefit of tubes sonically, a liquidity, air, and dimensionality, not usually available in SS stuff, in my budget anyway, you can if you wish alter the tone by changing tubes. For example you buy a new CDP - it has a bit of brightness, but otherwise you like it. With SS stuff you're kind of stuck, but with tubes you can usually accomodate the new CDP by just changing a tube or two somewhetre in your system.

From a pratical point of view, at least IMHO, the principal benefit in having a pre/power seperates is the flexibility it offers in being able to use different amps in the future, but also gives you far more alternatives when it comes to system tuning. For someone anal about getting that last iota of tone, seperates are a must, if for no other reason that sooner or later you're going there. Just go in the first place. But, by the way you have described your needs, I would think that a good tube integrated would be a great choice. While it might minimize your options it will also minimize your angst and let you enjoy the music.

Tvad has mentioned some other integrateds that could work for you - there are others as well, however if you decide to research these units pay careful attention to the tone issues. Your BK amp has a warm signature (I used to own one) if you get an integrated today which is described by reviewers as neutral, compared to your BK you might well find it bright, not neutral. A unit described as warm, you might consider neutral. There has been a substantial change in usage of these terms in the past 30 years. The emphasis today seems to be placed on detail retrieval. Personally, I'm very wary of any review of equipment which dwells on this - i.e. "I heard sounds on my favorite record I've never heard before". Usually all this means is that the unit has either an up-tilted high end or the amp is over damped and the normal decay time is shortened and you hear the highs more clearly, but artificially.

FWIW, I have not heard the other amps mentioned by Tvad. But, the PL's err on the warm side of neutral. The sound of the 1 would be far more of the sound of a tube amp from the 70's and 80's and the 2 would have more of the crispness found in todays tube amps, albeit still having a warm signature compared to a lot of the competitors.

JMHO, Hope this diatribe helps a bit.
