Cary SLI-80 integrated or AES Sixpacs?

I'm looking for a new tube amp for a system built around Harbeth Monitor 30's. Contrary to myths that Harbeths mate well with SS only, I've found that my office integrated, a Primaluna Dialogue II, sounds better (specially with Genalex reissue KT77s) than several SS integrateds I've heard paired with the Monitor 30s. I could live with the pairing, but I would then need to get another office amp. Given that the Monitor 30s could use more juice than the PL Dialogue has to offer, I have been looking around for a more powerful tube amp under 3K (new or used) that fits other constraints (which I'll spare you). Although I'm open to other suggestions, I was thinking that either the Cary SLI-80 integrated or the AES Sixpacs (with an AES preamp) might do the trick. I could carry the Harbeth to a Cary dealer to audition the SLI-80, but I can't audition the AES. I was hoping that someone who has experience with both amps could speak to their relative merits.

My main source is apple-lossless files streamed through a Wavelength Brick DAC (mostly jazz and acoustic stuff). Room size is moderately large by NYC standards (20'x25', 12' ceilings), but the set up is close to 'near-field', 7' away from the speakers.

hi,

I have Harbeth compact 7es speakers and use the Cary SLI-80 in the ultralinear mode most of the time to drive them in a 13x24 foot room. I listen to jazz and classical and am quite happy with the combination. To get 3db more head room you would have to go to ss amplification, and I find the Harbeths and tube amplification is a match made in heaven.

Thanks for the responses Cruz123 and Mds.

Given my experience with the PL Dialogue, I'm certain that I would end up in triode mode the bulk of the time. That puts the SLI-80 at 40w and the Sixpacs at 50w, effectively doubling the Dialogue's 21w triode mode. Now I appreciate that doubling watts has a modest effect on clipping and perceived loudness, and I know that the Harbeths will sing with more power, but 40w-50w is at least within the recommended minimum for the 30's. The sensitivity of the Monitor 30s is close to the Thiel CS1.5, 85 db I beleive, but their impedance curve does not drop below 7 ohms (see, http://www.soundstagenetwork.com/measurements/speakers/harbeth_30_domestic/ ) . Nonetheless, I would be open to any recommendations for higher power tube amps.

Thanks again.

Larry,

Thanks for the input. I had been using the Plinius 9100 SS integrated with the Monitor 30s. I thought the combination was quite good until I heard how the famed Harbeth midrange sounds driven by tube amplification. No looking back now, even at the expense of some head room. Speaking of which, how do you find the triode mode as compared to the ultralinear mode? The ability to switch is a definite plus for the SLI-80.

If you're considering purchasing new, give Kevin Deal a call at Upscale Audio. Kevin can also with tube selection to bring out the best of either the Cary or the AES. I purchased my Six Pacs from Kevin, and if I was in the market for another set, would call up Kevin again.

Make sure to audition the CAD 120S. I have a new one w an SLP98P preamp and it sounds fantastic. I traded a V12R for it. The amp also runs much cooler, and has plenty of power, even in triode mode. Good luck.
