Compared to my Pass Aleph P, the Forte had a noticeable "electronic" sound. The BGs and diodes removed much of this. I used silver wire just because I find it particularly clear but neutral in preamps - silver is very nice in small amounts. I removed and grounded un-used inputs (every other input as per the selector SW) just to remove crosstalk between sources. Overall, the Forte is a little more quiet and a little more natural sounding.
Maybe someday I'll finish it off with dual regulated power supplies and perhaps a stepped attenuator. Overall, the design is fantastic for an opamp based pre - there's really not much to improve on in the audio circuitry. The phonostage is one of the finest I've come across.
