Not certain if this will help, given the impedance swings of the Amatis, but- you might contact Speltz, or Ralph Karsten(of Atma-Sphere) and inquire. Ralph used to offer a transformer, in his product line-up. http://www.zeroimpedance.com/products.html As far as a, "rich" midrange: just pick some NOS British valves(Mullard, Brimar, Ediswan) to use in your input/driver stage, whatever tubed amp you choose. Generally speaking, they tend to warm things up, quite a bit. The Cary 805's have 4, 8 and 16 Ohm taps and at 50 WPC, you may find a sweet spot to satisfy your tastes(if you're not into high SPLs).
Cary 805 questions; with Sonus Faber Amati Homage speakers
I just bought a pair of Sonus Faber Amati Homage speakers (92 dB efficient but some impedance dips in bass and treble). Looking for a good tube amplifier. I use a Thor TA-1000 preamp and listen to mostly vinyl (Sota Star Sapphire, Koetsu Rosewood Signature. Half jazz, the rest split between blues, classical and rock. I am quite allergic to any treble brightness but appreciate treble extension if it doesn't create fatigue. That said, I prioritize a rich, real midrange, and like a somewhat laid back stage perspective.
Stereophile described the Amati load as "The speaker is a moderately demanding load, however, as can be seen from its plots of impedance magnitude and electrical phase angle against frequency (figs.1 and 2). With a maximum of 7.8 ohms, but a value below 6 ohms in the midrange and below 4 ohms in the bass and high treble, a good 4 ohm-rated amplifier will be called for."
I appreciate any thoughts about other tube amps that might be good with the Amati's. Also I have questions about Cary 805 monos in particular because I have a chance to buy a pair locally:
1. Do the 805s have a forward presentation?
2. Do the 805 create "larger than life" images? I owned them for a short time quite a while ago and recollect that images were very big.
3. Does anyone know if they would work well with the Amatis?
thanks for any thoughts!
