On a journey for the last couple of years

Soix,

Yes that helps as it will lead to an easier decision when upgrading the mono blocks. I just assumed that new more power would do the trick. I will continue to test various scenarios before jumping into new amps.

Very helpful thank you....

I like my REL T/7x, pretty sophisticated. And it's one of their low end models.

@peterrock Given the low frequency range on your speakers I strongly agree with the recommendations that a properly setup, stereo pair of musical subs will result in a much larger benefit than upgrading amps.  For a music focus I have become a big fan of REL subs based on their ability to seamlessly integrate.   REL's website has a selection tool for the recommended subs given your speakers/room that may be helpful to you.  For my system I have a pair of the No. 31's but also think the Carbon Special models are a great choice.  If you're comfortable with used, the previous Carbon model is showing up for some pretty favorable pricing.   

Ever consider bi-amping the Olympica 5s?  You could put a real ballsy amp on the bass, and an amp (or monoblocks) with a big sweet soundstage on the midbass/treble..

I’m a McIntosh fan(see my virtual system) but  would do the following in this order:

1. Room optimization 

2. Dual subs. I run two Legacy Audi Foundation subs. Made a gigantic difference.

3. Speaker placement and alignment in conjunction with #’s 1&2 

4. Get the MC611’s. Heck. Just get them anyway. Hey. I’m a Mac fan. 😎
