845 or 300b with Agalme?

To my knowledge, the Horning speakers regardless of the model are 96 db sensitivity (Or higher). They are considered to be a very easy to drive flat 4 ohm speaker impedance.  I found this description on “Mono and Stereo” website.

The new Agalme statement speaker [€36.000/pr] is built around the new 6.5-inch PM65 Hørning/Lowther driver with 2.4 Tesla field strength in the voice coil’s air gap. For bass there are twelve 8" woofers in a push/pull array. For treble augmentation there is a new spiderless cone tweeter with 99dB efficiency. Overall system sensitivity is given as 102dB at 30Hz and 99dB at 20kHz. Each cabinet measures 200 x 65 x 40cm, weighs 130kg and "is built to a very high standard wood finish".
 

With the specs you guys quoted would work fine with 300B. I've had two 845 SET amps, greater impact, authority with 845, 300B more harmonic development, sweeter. I love both tubes, probably can't go wrong with either. Make sure you have high grade power tubes in either case. Review of Thoress monos in Postive Feedback were supplied with KR 845, those top grade if they have durability issues resolved, I had failures with these tubes many years ago. Reinhardt hand picks tubes for his components, my phono enhancer has very nice NOS, point being I'd trust whatever tubes the monos were supplied with. Love the Steampunk styling of Thoress as well.

Agreed.  I feel that I could be just as happy with an 845 SET as I am with the 300b SET. Different but equally satisfying on their own terms with excellent implementation. I looked at the Thoress amplifiers (300b/845/F2A) before settling on the Coincident Frankenstein. I have no doubt that I'd be very happy with that choice as well.
