One warning on the TBI amp before anyone shells out the $500.
I was breaking in some new speakers this week, decided to crank them up last night. The sound was very lean and dry. So bad, the sound quality was a 3-4 rating. I quickly put a tube integrated and the magic came back, but a lot of the detail was gone.
Frustrated, I hooked the TBI amp back up, this time cranking the volume up to the max, using the computer for volume control. Bingo, there was the detail and magic back. Now the sound was a strong 9.75 rating. The TBI was now much better than the tube integrated I used on these very revealing speakers. At low volumes on the TBI integrated volume control, you will definirely not like the sound.
I have some AMR audiophile fuses coming in next week, I will see what those will do to the sound.
