ProtoDAC TDA1387 X8 project

Update on the tantalum I/V resistors. They always had a hard edge to them, even after 60+ hours of burn in, and it was not improving. Excellent soundstage, but fatiguing. Relieved to be back to the TX2575.

I will try a single 100 ohm tant with a preamp. Also, 100 ohm TX2575 and Rhopoint.

1. TX2575
2. Caddock TF020
3. Tant SMD 4 x 100 ohm

I am using AMRS resistors for I/V and they are very musical and cost effective. If cost is not a concern, I will use AMRG. Takman is another excellent choice used by Audio Note in Japan (not UK).
