Want to add, I changed the I/V opamps of the SB Titanium HD, and now it sounds a lot better. It has more warmth compared to stock, and with less anemic bass. Changed the apamps to Burr-Brown OPA2111 KP dual Low Noise DiFET opamps.
Stock sounds good and detailed, but too detailed, and anemic in the bass. Now it's warmer (though less "analytical" in detail, which I actually prefer), and with "rounder" bass. It's hard to exactly describe, but I highly recommend this op-amp if you have the SB Titanium HD for the I/V op-amps. I didn't change the output op-amps.
