Hi Unsound,
No, I still haven't addressed the room correction part of the effort, and I probably won't during the next few weeks. The microphonic tube issue I mentioned a few weeks ago was readily resolved with the purchase of a couple of NOS tubes. But subsequently an unrelated hardware issue arose in my system, which among other things has prompted me to put into motion a phono stage upgrade I've had in mind for some time.
So I've just placed an order with Herron Audio for his highly regarded VTPH-2 phono stage. It will replace what I have been using for that purpose for many years, the phono section of a vintage Mark Levinson ML-1 preamplifier (accessed via the ML-1's tape outputs). I should receive the VTPH-2 in about two weeks or so. I've also ordered an Adona isolation platform for it to sit on, and I may have to also make some changes in the system's power distribution setup.
I'll then want to spend some time familiarizing myself with the sonics the VTPH-2 will provide, and perhaps also give it some additional burn-in (although the burn-in and test Keith Herron provides prior to shipment amounts to 48 hours, according to the manual).
After the dust settles on all of that, I'll resume the process of dialing in the DEQX.
Best regards,
-- Al
