Tube Mono-Block Recommendation

More information is needed, especially what speakers you are using, and whether or not you need power levels approaching the 305 watt capability of the Carver.

Dragon_vibe, the impedance curve for your speakers, as shown here, suggests that the tonal balance of the sound that is produced in the mid-range and treble regions will vary dramatically as a function of the output impedance and damping factor of the particular amplifier that is being used. And probably also with the robustness of the amp's power supply.

So I suspect that in the $12K price class you are considering, synergy between the amplifier and speaker could very conceivably be a more significant consideration than the intrinsic sonic character of the particular amp. My suggestion is that you research what amplifiers are being used, and have been used, by others who have your particular speakers.

Almarg thanks for the technical info, honestly I have no clue. What would you suggest? Mind you this is for midrange and Tweeter level. The speaker has its class D amp. I could always Bi-amp them using the Clayton Audio for the lower Woofers and the Tubes for the mids and tweets.

I have no specific suggestions, as I have no experience with Legacy speakers. My point was simply that the large impedance variations of the speaker in the mid-range and treble regions, as well as the low impedances and difficult phase angles that are reached at some frequencies in those regions, will cause the resulting sonics to be more sensitive to amplifier differences (particularly output impedance and damping factor) than would otherwise be the case. But without having experience with the particular speaker I have no idea what particular amplifier output impedances and damping factors would be optimal. (Output impedance and damping factor are inversely proportional to each other, so damping factor can affect sonics at mid and high frequencies as well as low frequencies, due to the interaction between output impedance and the variation of speaker impedance as a function of frequency).

So I would be hesitant to give a great deal of weight to amplifier recommendations that are based on experiences with speakers other than Legacy models having similar impedance characteristics.

Good luck in your search. Regards,
