Good speakers under 10K.

A couple of weeks ago I auditioned a pair of Sonus Faber Cremona M's. They were seductive and addicting. I think they have that balance of warm musicality vs. detail that you describe, and they'd certainly excel on all the kinds of music you like.

Yes, they list at around $12K, but it doesn't seem to hard to find them under $10K. When you add in how physically gorgeous they are, it's a beautiful combination of virtues--looks, construction, design, fit 'n' finish, flat response, detail, warmth ...

And their maple slat construction really works. The Stereophile measurements of various Sonus Faber speakers (especially the slatted ones) show unusually low cabinet resonances. This translates into great low level detail in the proper perspective and the ability to play complex music such as classical with clarity, even at volume peaks.

How about Gallo 3.5, Aerial 7t, Sonus Faber Luito, Focal electra or Tidal speakers?

The reviews I've read of the Liutos indicate that they're sort of a "lite" version of the Cremona M's. There's one less woofer and the Liuto's use a dome tweeter where the Cremona M uses a ring radiator, which tends to have more speed and detail. The Liuto is considered an excellent speaker at the price, but I found the Cremona M to be ... breathtaking.

The best news is that the Cremona M setup I heard was being driven by a $999 Marantz PM8004 integrated amp. This amp uses the HDAM circuit making for an amp section with a s/n ratio of 125 dB. It was a fantastic combo. So what you spend on the speakers, you might be able to save on the amplification.

The Philharmonic 3s are only $3.5k new and they probably would meet your requirements.

Order by July 12 and they're still $3K. Not bad when you consider that a DIY-er would be paying almost $2K for the drivers alone.
