I think the instructions had R11 or R13 recommended. Does anyone have any other recommendations? How about the insulation that they sell at Parts Express?

I hated to put the guards on but I have two of three in the audiophile's unholy trinity: kids and pets.

Anyway, let us know when you get those ports installed. I like to paint the ports black on the inside, makes a nice contrast to the wood grain. It's easy to do with a little bottle of Tester's black enamel too.

Still don't have the ports in but put some R11 in on 3 sides and WOW!!! what a difference! Sounds much better

Then my Sonic T-amp came in via UPS. Hooked it up to the Bottlehead Foreplay and the 2pi. Heeeheee even better. My wife can have her Yamaha A100a back now (it's fish food).

Next up is tearing apart the T-amp and putting it in an Art Taylor chassis with upgraded parts (see previous pic) and a modded UPS for a power supply.

When I'm done I'll still be into the setup for under a grand.

Bottlehead Foreplay $200
T-amp w/ chassis $200
Pioneer DV-578 $140
Rat Shack interconnects $40
2PI Speakers $400

And most will have been DIY.
