how much tube power for eclipse ?

Tim, you're probably underrating Rogue that has a transformer tolerable to large impedance swings as well as VTL. It's just simply not with the same class with Avalons but can play them for sure. Later-on magnum upgrade can be done. If it can drive Thiel 3.6 than Avalons I think is easier.

Again, for the millionth time, if you want a super valued
amp that will drive the eclipse, then try getting the
Spectral DMA200 for about $1500. It drives my Radians and
my Acoustats, without any problems except when I decide
I want to bruise my ears with 110 db sound pressure. The
Rogue 120s or even the 60s should work fine for any thing up to 90-95db.
Which is very loud, concert hall levels.
You figure 85db/1m and at 3m listening distance that brings it down to around 80db for 1 watt; 90 db is 10 watts; 100db is 100watts; 103db is 200watts. Also the DMA200 does not need a Spectral preamp.

Hi Glen45,
I have a pair of VTL 80 watt mono's I use with my Maggie 1.6's(84db). My room is 14x16. They sound great! Big powerful sound. If your interested they are for sale @ 950.00 OBO.
Let me know
