Try some KT 150s in the amps! :)

KT150 tubes are on my list... I thought I'd go ahead and run the amp through break-in using the stock tubes. Then, just when the amp is at its musical best, slip in the KT150s for even more sonic bliss. :yahoo1:
 
Oh hell, why wait? I went ahead and ordered up a quad of KT150s. Bring on the sonic bliss!

The Wilson dealer came on Sunday and spent six hours WASPing the Alexias. They are pretty close to the back wall, much more than I would have imagined. And the tweeters are 12.25' apart, which has my listening position about 15' back. I had some older, broken in REF gear for the setup, then just swapped in my new REF10 and REF75 yesterday. I found new positions for them today, and they now have 4 hours.

I spent a couple hours listening tonight in the almost darkness, with the meters turned off. That little REF75 is quite the amp. It drives the Alexias fine. And the room sounds quite good even with only the tube traps in the corner. If I run the volume up into the 90+ db range I hear things getting a little reverberant and confused with rock and orchestra, so there is some work to be done acoustically, but not so much I am not enjoying the hell out of having music again. (And tonight with a nice little Italian red! Wine that is!)

Bob - do you have a spectrum analyzer that you can use to monitor the peeks of the specific frequencies? If not, I use this one on my iPhone for a quick and dirty analysis. (See below). You may want to get it, put it on the FFT plot mode and have a look. You want to identify where the specific peek(s) are in your room. Mine was 73hz. Above 90db excite which frequencies in your room?

Nice digs!

I have an idea, we swap houses for week. You can enjoy the forest here, my sweet wife and I get some beach time!
 
Excellent Mike, thanks. I'll download that app. Did you use a specific test source with that tool?

I used pink noise, but also songs which seemed to excite certain frequencies. Try Diana Krall - Narrow Daylight (from The Girl In The Other Room album) or the entire Bob James/David Sanborn album Quartette Humaine. I have other too....but that's a good start.

Your room is gorgeous Bob, congrats.

Yes they do look a little too close to wall, but every room is different, tape them out in that spot and then play around with them.

+1000 on the KT150's

Thanks for the lead. I've downloaded a couple and just added this one for fun!

I thought the thing that was missing was a turntable. Screw the wine! :P

Turntable is being setup, wine club deliveries coming frequently this time of year. In fact, I'm upping my count from the "rare washington wines club" because so far I'm really loving this club. Re the turntable, I just got a new stylus force gauge so can finally dial in the LPS.

And Mike, my brief and hasty pink noise test @85db shows my peak at 63hz and of course also its double @125. I'll get a little more granular later, to see just how high the bump is, but at first glance the overall response was amazingly flat.

I find Audiotools is a better iPad suite. It also costs like $50 bucks though. I use the internal iPad mike (which is adjusted by the app)- its not that bad honestly. I had an acoustics guy out to setup my speakers and he was seeing similar things in the bass through his full mike setup.
