For classical music lovers best amp for large orchestral forces?

I love the xa25 and the int25 but I didnt like them for classical. They fell apart very quickly when turned up to even moderate listening levels. GI really enjoyed the gsi75 and LM 845-premium were incredible- especially with classical. You had mentioned you have a pre so youre shopping for seperates - that being said one of my favorite amps, and you can find them used for about 4k, is the magnus audio ma-400 - a simply incredible amp. I regret selling it to the day. I had a tube front end on it and Joshua Bell has never sounded better at high volumes in my room. Best of luck in your search!!! 

My next amp is coming from Odyssey!  Best deals ever ... yes, ever

ghdprentice is giving you the right info. I used to sell Arc stuff and the best symbiotic relationships were Arc connected to Arc. Either the Ref 75 or 150 will do you quite nicely.

Thanks very much for all your suggestions. I had the VTL S200 a while ago and I loved the sound but I found it a bit temperamental and I found dealing with the company not the easiest thing in the world. They do make a wonderful product. But it is a pleasure dealing with arc and pass.

I have been thinking about matching it up with arc but I am a bit leery of matching it up with used tube equipment as opposed to solid state as a used tube unit I bought had a lot of problems. So I bought this arc pre new. Therefore it used up quite a bit of my budget.

Still the 75 and 150 sound wonderful...

I will also read up on bi-amping as that might be cheapest of all.

I appreciate hearing from a musician like dancarlson10 because there is among certain classical music lovers the idea that a person who truly loves it should not be so much into their sound system as it is the music and performance that count. While this is very true a great sound system makes it all the more sweeter and emotionally involving at least for me. Also I've as well felt how a system handles large symphonic forces is the true test. If there is transparency, layers of sound, depth and the creation of a beautiful tapestry all other kinds of music fall happily into place whether it be rock, folk or jazz.

Thank you again.

It might be your Epicon 8’s are the problem.  A Trio is easy for most systems to reproduce, but the more things a speaker has to reproduce, the harder it is, especially at higher levels. 
 

BTW, Congratulations on the Ref 6se.

All the best.
