300w tube amp monos - which one?

Buy a secondhand pair of McIntosh 275's and parallel the outputs of each amp. This will give you 150 watts per side - only a 3db difference from 300 watts!

we have sold over the years many high powered tube amplifiers from vtl cj zesto manley to date the zesto eros have been our favorites high power tube monoblocks

quiet long tube life great bass huge soundstage great features

the vac iq gear are verv impressive but are very expensive arc sounds too much liks solid state cj art amps were fantastic except the zestos sounded just as good for less.

At this level you want to hear them.

I am very much an Audio Research person, but recognize Conrad Johnson and VAC in the same general sound space. MacIntosh is very different sounding. Not very detailed with massive bass and midrange… the muscle car of the above group.
 

I have never heard a high powered tube amp sound brittle. Particularly not in this group. But solid state sound very different… generally not as lifelike.

What are you looking for in an amp?  I have not heard any extremely high powered tube amp that I would want.  If I needed such extreme amounts of power, I would look at solid state.  Most of the high powered tube amps have a "brittle" sound, to me, and are somewhat harsh sounding.  High powered solid state sounds less harsh; the downside being a kind of lifeless and unengaging sound unless the volume is pumped up a bit.

I don't know of many speakers that I like that benefit from this kind of power.  Most of the stuff I like can be reasonably powered with 40 watts or so, and there are 40-100 watt tube amps that sound pretty good.
