Tekton Double Impacts

evolvist -  30-100Hz is going to be the tough nut. The rest looks straight forward although I should pick up that "Get Better Sound" book just to be safe. From the reading I've done, conventional air velocity traps aren't nearly as effective as diaphragmatic absorbers.

MSR Dimension 4 Spring Trap is looking promising. What the pair of MSR Spring Traps miss may be cleaned up with GIK tuned membrane traps.The stereophile review with decay results is impressive.

 I see some folks recommending Hedback Acoustics for consulting/design, but these folks need to get paid to do their modeling and consulting and I'm guessing the result is outside my budget. He uses foam bass traps in the corner, go figure. Wish there was some room mode witch doctors that weren't selling their own wares offering an unbiased opinion on treatment efficacy.

Dennis from Acoustic fields has an interesing diaphram/activated charcoal design but I can't make sense of the measurement results.

Any suggestions for low bass room mode absorption?

Thanks David, I hope to hear FedEx drive up any minute so I can share my impressions of the CF DAC. 

LOL Kenny, I don't think there's any help to be had for any of us here......thankfully! It was a tough choice between the 2A3 you ordered and the KT 120 I ended up ordering. The KT 120 gives me output options from 9-22 watts that ended up being the difference. Who knows, I might end up getting the 2A3 down the road to have both. Yep, I need more than a doctors help!

If I were to get a tube amp, I would have to look real hard at this:

Snagged an AURALIC Vega DAC on ebay for $2k.  Figure for that price it would be worth trying.  

@mac48025 - What is a CF DAC.  I couldn't find it online.  Hope you enjoy it and post on your impressions.  I'll be waiting on FedEx friday on my DAC.  Waiting sucks. 

Jcarcopo,
It’s the Japanese Concert Fidelity DAC and exceptionally good sounding. It’s a non over sampling design and ln my opinion is "very" natural in sonic character.
