I hope to get back downstairs and start adding back in the sound treatments tomorrow, unless we have a snow day. Thoroughly enjoyed having someone else get a shot at moving things around, tweaking, etc.
I'm glad Rich suspected we needed a tube change in the mapletree preamp. We put in the Sylvania 12sn7's. It really helped the veritas 2way we auditioned. the speaker just opened up with the highs, it had a dull washed out character right before we switched. With those same tubes in and switching back to my Riferimentos, the highs became more aggressive on the SS aircirc tweeters.
Of course to tackle the speaker placement repositioning, we removed all the acoustic treatments on the front wall to get to a bare corner/wall starting point. I wonder what the sound will do when the treatments go back in? look forward to seeing what the effect is on the tube/aircirc room interaction.
