Avalon Eidolon Diamond and Tenor Audio OTL

Hello,
thank you for the answers.
The jl2 is working good (but not exceptional), but this amp dont' have the "autorithy" to drive this speaker... specially in the bass.
I heard the boulder 1060... and it is a completely other world. Since I am tube lover I am searching a better resolution and bass control; I never tried a OTL amp like the tenor, the fourier panther or Joule, and I am intrigued....

Costanzia,

I have not heard the Tenor OTL with Eidolons, but I would be concerned about the impedance match (not power output) for controlling the bottom end. I use an Atma-Sphere MA-2 Mk.II.3 OTL with my Eidolons (regular, not Diamond), and they are a great match together with marvelously authoritative bass, and the Atma-Sphere's have the neutrality, transparency, speed and resolution to complement the Eidolons well while nicely complementing the Eidolon's wonderful musicality and delicacy through the midrange.
.

Excellent suggestions of the Lamm and Atma-Sphere. Enjoy!

I heard a lot about CAT amps driving Avalon speakers although I have not used any for my Ediolon. Lack of authoritative bass- can it be your preamp matching with your amp? If not, you might want to look into speakers positioning. I noted very minute change even in a fraction of degree for toeing in or out would make a big different to the sound. I took couple of years to get the right position for Ediolon--painful! In only for tubes-my taste as well. Believe it or not, I tried many tube amps with Ediolon before and they includes Jadis JA-500,VTL Ichiban,VTL-750,Hurricane ASL,Audio Research VT-100MkII etc.. spent a lot of money. I finally settled down with technology which is more than 30years old--a pair of McIntosh 275 run in mono block (150W per channel). The mid is something I will die for. The bass -- deep and authoritative. These happen only after I used combination of 12AX7 and 12AT7 for the small tubes and KT-88 as output tubes. I paired these amps with CAT ultimate preamp. Ironically,these amps do not cost me a lot for such an expensive pair of speakers.
