Good partner amp for Egglestonworks Anda II

Other amps that I would recommend would be:

VTL MB-450 Signature monoblocks, if you like tube amps. These are very powerful, (450 wpc tetrode/200 wpc triod), tube amps, that sound very good. (They were what my one friend had immediately before upgrading to the Lamm M2.2s.) There is a used set on Audiogon for $3,500, which is a very good price, although they are for the original series, not the series II, which is the current production model, but for this price, it is probably worth it. (Note: These run fairly hot, so it might raise the temperature in your room a bit.)

If you prefer solid state, either the Pass Labs X350 (a 350 wpc stereo amp), which runs around $4,500 used, (also available here on Audiogon), or the Parasound JC-1 monoblocks, (400 wpc), which run around $3,500. (Both of these are very fine amps, but not quite in the class of the Lamms to be honest.)

I am sure others will have other recommendations.

I am using a Pass Labs X350.5 with my Andra 2's.

If Eggleston has not done anything weird to the Dynaudio Esotar tweeter, I think Spectron will be a good choice. Spectron has superb transparency and extension, something I find complements well with Dyn Esotar like Dyn C5 and SF Extrema. Comparing Spectron to McIntosh MC501 is like lifting a veil, I even prefer Spectron over Pass X350.5 in most cases.

I am using a BAT VK600SE with Andra IIs. I have also run them with a DNA-500. My room is 14 by 18 ft.
There is a ton of bass energy available from those 4 12" woofers. Why not take advantage of it all?

Thanks for all the suggestions, one thing I'm convinced of now is that they do need lots of power, does anybody have any thoughts on class d amplifiers, any brands out there have synergy with Eggleston house sound?
