Parasound - Pass Labs - VTL - Krell Amp Selection


Hi,
I noticed a similar thread to this a few days ago, from Punkawalla, but just wanted to add another variable or two.

I'm shopping for a new amp for Maggie 3.6's....the Krell I'm using is excellent, but I have the upgrade bug and would like a little more power for the 3.6's.

I've seen a few decent amps and just wanted some opinions to help me unravel the options and hopefully make the best choice.
Setup options steer me toward monoblocks, these provide the easiest integration into my room with WAF considerations.

I hope Sean spots this thread, since I know he has respect for Nelson Pass and John Curl, and wondered if ultimately he had a preference.
The amps I've shortlisted are all available used on 'Gon and I'm listing the prices to help with perspective:

Krell 350Mcx Mono's $7700
Pass X600 $6500
Parasound JC1's $3700
VTL 450's $4500

The Krell's at $7k+ are a little more than I want to pay, though if I could justify the higher price based on margin of improvement over the others, I would probably stretch to it.
The JC 1's seem like an absolute bargain, so much so that I'm skeptical if they can really compete against say the X600's with an original $16,000 retail.

The VTL's really whet my appetite, since I'm a tube kinda guy at heart. But, since I've bypassed fuses on the 3.6's, I must have peace of mind that the amps are capable of delivering the current that these speakers need and that there is no clipping at high SPL's. Also, I need to know that the internal protection circuitry is of high integrity....I don't want a tube failure taking out my tweeter(s).
I've read that the JC1's and the X600's have 'tube like' quality, so I guess I'm trying to achieve 95% of what tubes do best from a SS.

I've been trying different amps now for almost a year. My home office looks like an elephants graveyard (for amps and cables), and it has to stop!!
I need an amp that I can plug in and sit back and enjoy the music, without having to worry about power, or if I should have gone with tubes, or whatever else I worry about!!

My priorities are:
Good soundstage and presentation of scale.
Clarity - natural - openess.
Truth of timbre and natural non-fatiguing presentation- it all happens in the midrange for me.
Enough bass but not bass that overwhelms the midrange and hides inner detail.
Clean highs, maybe on the darker/warmer side of neutral.
Fluid - flowing presentation, not necessarily with the dynamic snap, pop and tizzle that many crave.

Everyone has a different opinion about these things I know, but I've had a lot of good advice here in the past, and I don't regret any choices I've made based on the advice that I've received.

Thanks much

Rooze, Pass is expected to release the X600.5 monoblocks early in the new year. You should also be able to pick up a used X600 pair and upgrade them to the X.5 new standard.
Thanks Muralman, I sent henry a note. As I frequently travel to D.C. I might be able to visit with Henry next time.
Loudandclear, Have you ever heard the H20 monoblocks driving Magnepan? I have Maggie IIIA and may consider upgrading to 3.6 or 20.1.
Muralman, that was a very lyrical and spontaneously drafted review, in the style of stream of consciousness.
Scott is comparing H20 to Aragon 4004 and reports a staggering improvement on MG 2.6 with H20. I am not surprised.
I have used the same Aragon 4004 from approx 1988 to 1998 on the larger MG IIIA pair with very moderately satisfying results. Soundstage was relatively flat, imaging was arguable, bass extension a promisary note. . . no need to beat a dead horse, but Aragon never attempted to be the epitomy of our high end: a good price/performer does not imply stellar performance.
Scott also mentions trying several other brands, without being specific about models. AS Maggies present a relatively difficult load, it is relatively easy to find a poor match for them.
I am currently driving my MG IIIAs with a pair of venerable, yet incredibily sweetsounding Rowland 7M, which while driving the speakers completely effortlessly, could be replaced by something a little faster and detailed.
It would be interesting to find a more dispassionate reviewer who can compare the H2O with some higher end amps than Aragon: the upcoming X600.5 from Pass for one, Rowland 301 monoblocks, ARC VTM 200, and other devices in the same or even more exalted legue.
H2O is likely an excellent price performer, But is it a stellar performer regardless of price?
I am looking forward to any analysis that the folks of the Wisc Audio Society and others will provide on the subject.
Thank you MuralMan, for everyone's benefit, I have found the H2O site at:
http://www.iceh2oaudio.com/
The fact that you and others are applying these creatures to the voracious Scintillas makes me feel good. I am looking forward to reading more reviews and eventually hearing them. By the way, where does Henry Ho reside?

Spoke to Henry. I found out a couple of technical details about the H2O mono amps missing on the web site:
1. They are a full balanced dsign with both XLR and RCA inputs.
b. The power supply is an analog, continuous Power supply, rather than a switcher.
c. The amps can generate 20 amps continuous and approx 50 amps peak.
Very intriguing Muralman! A comparison of H2O with X600 is exactly what I am seeking. Did you already mention in some thread what speakers you are driving?
Are you planning also to audition X600.5 when they become available after CES? It is my understanding that the new monos will be much improved.
