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.

OK, I did look into LFD and, wow, you’re right, what over-the-top praise! Jaw-dropping!

But unfortunately (please don’t hate me), you can’t always select a piece of gear as a sole function of sonics. And before anybody brings out the garlic and crucifix, I’ll point out that if that wasn’t the case, we’d all be listening to Chronosonic/D’Agostino systems. (And half of us would be divorced!)

In my case, I need a fair amount of connectivity, but the LFD line doesn’t even seem to have outputs for a powered subwoofer or external headphone amp. Or even a remote. IN fact, I’m not sure how it could be used with smaller Harbeths that roll off at around 45-50Hz. Even my Quad ESL-57s benefited tremendously by adding a sub.

I guess I could front-end an LFD integrated with an exceptionally flexible DAC, like a higher-end HiFi Rose unit that would add much of the analog & digital connectivity I’m looking for. But I'd still be missing a few crucial connections.  And that would be a whole new research project.

What’s disappointing is how little info there online is about LFD's product line. I haven’t found a review that tabulates even the most basic specs, like size & weight, power rating, or even price.  And even Gene Rubin’s Web site doesn't tell you much. After an hour online, I still can’t figure out which models are in the current LFD product line, much less compare them. LFD itself doesn’t have a working Web site.

What I’m gathering is that LFD is a small boutique operation, something like George Merrill’s GEM. I’m a big fan of bespoke equipment -- my GEM turntable is aptly named! -- but the downside is that I’m not sure how to make an intelligent purchase decision.

Nonetheless, I’m tempted to pick up a used Mistral on eBay (used units start at around $2000) and hang onto it for a bit just to hear what everybody’s talking about.

Anyway, thanks for teaching this old dog a new trick. LFD has now definitely caught my attention.

Have you checked this review ?

The best match for the Harbeth 30.2 40 th was the Pass Lab X25. I've got this match: Fantastic! Just need to pick the preamp that best fits your source, analogue or/and digital. And you're in business.

I just spoke with an LFD rep, who confirmed that the company’s amps can’t be used with a speaker system that requires a subwoofer. There’s no way to get variable-level output to a sub.

Too bad. I was actually thinking of buying a used unit on eBay just to play around with for a while. They run from $2500-$5000, so it would be an indulgence, but you guys have got me curious. But now it sounds like it might be more trouble than it’s worth.

If I was younger, though!

During my misspent youth, I used to buy a lot of "junk" 1950s & 60s tube gear made by the likes of Quad, restore it, learn from it, listen to it for a while, and then ultimately resell it for whatever I’d put into it.

But these days, I just want to hit a button, sit back & listen.

You can use a subwoofer that can take high level (speaker level) input. Many subs today (REL, SVS, Rythmik, KEF etc) have connectors to accommodate both high and RCA line level input. Basically connect the sub in parallel with the main speakers.
