Butler amplifiers

I have had the Butler 5150 (5 channels of 150 watts) in my home theater for several years now. It could be characterized as having a sound (in my rig) akin to a push-pull tube amp with a dash of solid state seasoning. Then again, I do absolutely no critical listening with this rig and speakers are modest (Definitive Tech); never hooked it up in my main music system. A good, solid amp which serves my needs quite well.

Reading some earlier threads and the above contributions, one gets the impression that this amp is a good honest outperformer but not one that I should consider for an absolute high end setup . Any comments from people familiar with this amp in regards to my statement please.
How does the Monad compare with the very best SET or SS amps out there and how does it compare to the 5150.
Thanks

Ecka - you are correct in your assessment - it is not the last word in anything - it is solid, very enjoyable piece for the system and listening environment I have - as well as what I had to spend. (The 5150s sometimes come through on Agon at some pretty compelling prices)

If you have OTL or Pass xxx.5 money and you want the ultimate, you should go that way
