Almost there but not quite....

You have a problematic room. You certainly are sitting in a near field listening position. I would expect you are losing a lot of air and spaciousness due to that listening position. Is a short wall configuration possible? Try to get further away from the speakers, they need some room to breath.

Awesome speaker choice Musicfile, I'm very familiar with them and Intuitive Design Deltas (also of granite)

Thx Rx8man

While the room may be problematic the Sasons sound excellent in their current room configuration If I wasn't such a stickler on acheiving that last ounce of musicality hence the sickness I should shut up and just enjoy the music

If you have very good sound already, you could try some tube rolling. Amperex tubes sound very good in the Mantissa preamp...I use 7308's, or 6dj8's in mine. Both have very good sound IMO, the 7308's are focused and vivid...everything in it's place. The 6dj8's are less focused, more bloom...a little more forward sounding.

I have RCA clear tops in the front...(not, as big a deal).

Of course the room is some amount of problem, but you already know that. I suspect the long wall placement and near field listening, are the cause of a more neutral sound, and with less air. (probably not a bad thing in that room)

And you are right....sometimes it is the album, and not the system.

Thanks Dave for chiming in with your comments

I currently have amperex in both positions of the manitissa 6dj8 and 7316 the sound is very good. Part of the neutrality i'm hearing is my Mantissa is decked out with vcaps through out which imparts a very neutral sound and the Sason's are as neutral as can be but are highly musical (Well thought out Kudo's to RSAD guys)

At this stage I was hoping to warm things up a bit...perhaps adding a bit of warmth by way's of a tweak i've heard maple blocks underneath components or a Power cord in the right position could do the trick

Any further opinions appreciated
