Electronics for Harbeths -- $5-10K


I've been looking for an amp/preamp or integrated to pair with my mid-sized Harbeth speakers (86dB sensitivity, minimum 6ohm impedance, ~50Hz crossover to a powered sub).

I've dug deep into Pass Labs, ARC, Levinson, HiFi Rose, PrimaLuna, Ayre, MF's Nu-Vista line, Hegel, etc. -- the usual suspects. But I haven't found a perfect fit, b/c I have a few constraining requirements:

- weight not much over 40 pounds

- an HT Bypass input and at least 2 line-level outputs (for powered sub & headphone amp); no digital inputs required

- I love well-designed tube gear, but in this case, I'm restricted to SS

In terms of sound -- the most important factor, of course -- I rarely't exceed moderate listening levels in a smallish room (10 ft to seating position).  I do, however, enjoy a large, three-dimensional presentation & uncompressed dynamics, and sonics more like the sweet, tubelike house sound of ARC & Pass than the "analytic" superdetailed sound of Luxman or Levinson (both outstanding companies, but just not the right fit in this case).  One motivator is that after recently switching to more revealing Analysis Plus Silver Apex cables, I find I can no longer stand the sound of my last-gen Class D amps.

A Pass Labs XA25 amp + SP-12 pre combo comes pretty close, but doesn't have quite enough power. MF's new NuVista 800.2 would be perfect if it didn't weigh nearly 90 pounds. 

Then there's Ayre's new VX-8 amp, or EX-8 integrated, sound great on paper, but which I know almost nothing about, aside from specs & a Stereophile review.  Anybody own one of these?

I have no opportunity to demo any of this gear live -- disabled & don't get out much -- but if anybody would like to recount their first-hand experience finding a soulmate for Harbeth speakers, I'll be listening.

re: Luxman, I've never heard the new Lux gear.  When I refer to the Luxman sound as "analytical," I'm merely repeating what other, ostensibly unrelated, posters have told me.  I'm ready to be convinced otherwise, but, as I'm sure you can appreciate, I don't have much to work with other than what other people are telling me.  Again, no way for me to actually hear any of this gear before I buy.

Re: Silver Apex, your observations are exactly the opposite of mine.  The only time I rigorously A-B'd my SA cables was when I used them to replace wiring in my phono path.  They produced greater detail and a more holographic soundstage, sure, but they were less sweet and as far from tube-like as I can imagine. (Did I mention that I'm a vintage tube-roller going back 40 years? I know what tubes soudn like.) 

More to the point, one reason I'm upgrading my electronics now is because the Silver Apex's "analytic" character (sorry!) actually made the flaws of my $2000 Class D amps impossible to tolerate. 

I consider the difference between our experiences evidence  that the only way to know what a particular cable will sound like in your system is to put it in your system.  Cables are extraordinarily complex beasts and can interact with other components in the craziest ways.  That's why I NEVER recommend specific cables to friends. My approach has been to learn first-hand what each mfr's "house sound" is in your system and then stick with the brand that best matches the sonic personality you need.  Analysis Plus and Audioquest (strange bedfellow, I know) seem to work best for me -- at least on segments of my system that don't include Class D amplification!

helomech: "$5K-$10K amplification is going to easily outclass your speakers such that the Harbeths become the new bottleneck. I understand why that would be hard to believe given all the hype surrounding this brand, but take the Harbeths along and compare them to nearly any $10K/pair speakers on $5K electronics and you’ll understand why I say this. The resolution required to justify most $5K^ amplification (especially in the bass and highs) just isn’t there."

helomech: Hmmm... Don’t take this wrong, but your comments are at odds with those of every other person I’ve spoken to, as well as with my own first-hand experience. As I’ve mentioned, there’s no place within thousands of miles where I could "take my Harbeths." But more to the point, given that your opinion is incongruent with those of so many knowledgable, experienced persons -- from Hartley and Atkinson on down to buddies with Golden Ears (even the late Art Dudley personally recommended Harbeths to me when I was forced to sell my Quad ESLs) -- please let me know why I should take your conclusory opinions seriously without any details to back them up?

E.g., Are your comments based on first-hand direct comparisons?  If so, please be specific about source material, associated equipment, and room characteristics so others can put your observations in context. If you have something of value to offer, I would certainly give it consideration.

Thanks for your comments.

I was referring to the Acrolink 8N-A2080III having a warm and liquid midrange with a tube-like glow in the highs, not the Silver Apex which you currently own.  I don't have experience with the Silver Apex.

I agree with this. The only difference is I will recommend specific cables which I have experience with to people whereas you don’t do that. To me, cables are the same as other components such as amps or DACs. You will only know if it will work out for you once you have it in your system. The point I’m trying to convey is you may achieve your goal with a different cable rather than looking at changing amps.

Ah! So much for my reading comprehension!

Your recommendation is a good one, but I think regardless, an amp upgrade is long overdue. But you’re making me think that I might need to incorporate a cable re-evalution at the same time.

What’s interesting is the fact that the amps sound the worst when fed by 100% Silver Apex cables. Yes, there are a zillion other factors that make each signal path unique in its own way, but still...

One possibility is that the Silver Apex segments sound the most Class D-ish because they’re the most revealing. Unfortunately, it’s not easy to swap them all out, since some have singular connectors, like the tonearm cable.

Regardless, I would hate to give up those expensive cables. They’re so impressive, even mind-boggling, in terms of presentation and detail. No other upgrade that I’ve ever made in this system has done so much to promote a broad, truly 3-dimensional soundstage. After I inserted them into the system, I could not stop listening to vinyl. The endorphin rush -- the thing that keeps so many of us in this hobby -- was intense.

I just hope that swapping a $2000 amp for an $11,000 amp produces as dramatic an improvement.
