Sonus Faber Guarneri's


I'm mulling the idea of dialing up the performance of my second system and am considering the SF Guar's. I have an AirTight 8W SE amp driving Spendor LS3/5A's, so I'd need more ooomph from the amp (looking at a Lectron JH50). So any comments on the SF's - haven't heard much lately - vis-a-vis the Spendors? Speaker cable recomm's (I have AudioNote KSL copper now, thinking about Omega Micro...)?

Also, I know SF changed the construction from 8 to 7 panels a few years back, and thought I remember a possible tweeter change about then also. Any advice on new versus older model?

Thanks for the feedback.

Thanks mucho Greg.

I've always had the SF's in the back of my mind and now that I'm going to change amps, I'd like to do so with them in mind in the future. I'm looking into a mod'd up Lectron JH 50 - an EL34-based 50W tube amp - and the person doing the mods has the Guarn's with the same amp and says it is a wonderful match. Literature says 30-200W needed, but with the 200 staring at you (and the sentitivity) you know what that really means. I have a smallish room for this system and mainly listen when I'm writing or take a break for a glass of wine or have company over, so not as critical for that sit-down-and-immerse-for-three-hour-experience, or for loud listening. My problem is that I'm VERY picky on mids and on the musicality route even in that context (I've also been a stalwart Quad owner in the past and if don't go with the SF's down the road may go back to the Quads, and the Lectron would be good there too). The Gaurn's sounded like they'd fit the bill (I heard them years ago, but didn't hear as well then, but liked them very much). I mostly listen to violin, live jazz and blues and female vocals and piano on this second system, so I can also work within those parameters.

We'll see...

Would still like to hear any comments, especially on the old vs. new models.

Thanks again.

Hi Mark, the newer version is supposed to present a more "benign" load and sound vs. the older version that was a wilder beast more difficult to "tame".
It also seems that many SF resellers were having trouble selling the G's... Allegedly NOT because the asking price was high for the speakers but, rather, because the price for appropriate electronics went through the roof.
This is hearsay, I haven't actually gauged the differences myself: in a well treated room (dealer's) and driven by the same 250W class A machine, I hate to admit that old & new version G's sounded nearly identical to my ears... whatever.

A note about the sub: our experiments above were conducted WITHOUT the sub (SF's big one). We wanted to solve the driving issue disregarding, as far as we could, the low frequency roll-off (it was -2db @ 45Hz in the room).
In this respect, and as Mr Hiraga's machine is being modded with these speakers in mind (heavy duty caps will move into the PS, I suppose!), there shouldn't be a problem. But you do need a minimum amount of power to get correct sound from the G's, however low the volume. I would assume that the nominal rating required for a good tube could easily be half that of the equivalent ss... Cheers
If you decide on the Sonus Faber, consider the VAC 70/70 MkIII-S Ren as it will be a highly recommended match. I mention this not only because I have one (VAC) for sale but because from experience it is one of the best synergies I've heard.
Thanks Gregm and Mjc. Probably a couple of years off on the SF's, but some of my buying decisions now will effect that system, so I wanted to start mulling it over. You've given me some great advice. Thanks again fo the help.

Mjc: on the VAC, yes, I am familiar with it - nice piece. My problem with it is all the 300B outputs. NOS systems ALWAYS sound better if properly done, and you are pretty much left with the Golden Dragons that VAC distributes if you want to run the thing, ie. for me, at least, drudging up multiple pairs of new issue WE300B's at $400 a tube - and you really have to because the GD's sound harmonically brittle in comparison - gives me a cerebral hemmorhage just thinking about the expense, much less the logistics! Thank you, though, a good choice. I think I'll end up with a Lectron JH50 EL-34 based amp, or, more likeley, a Cary 805 SE (not a push pull SE like the VAC).
Just another thought and possible option. I use a pair of Pass Aleph 0 Monoblocks with my SFGs. Very reasonably priced on the used market. Rated somewhere between 50 and 75 watts rms - fits nicely into that window of power recommended by many SFG owners. Known for a SS design with very much a tube sound. Warm, transparent and detailed. Mid range to die for. Almost too much of a good thing when driving the SFGs. The Aleph 0 Monos do have feedback and do have three stages - different than the rest of the Pass line which are designed with no feedback and 2 stages. The two stage designs also have a rep for incredible mids and tranaparencey but no "umph" to drive the bass needs of certain speakers. The Aleph 0 Monos provide incredible bass - fast, very articulate but rounded and full. A great fit for the SFGs. I am also using a Joule Electra 150 Preamp, Golmund 29 CD Player, VPI Aries and Memorial Arm, and Van Den Hul cartridge. Just bought a REM Stentor III sub and I am still evaluating it's impact and contribution. Again, all of these component choices (except for maybe the Van Den Hul) point to my specific lust for midrange warmth and detail.
