Looking for an upgrade to Vishay-Telefunken BYV-27-150 diodes wired in parallel for my TDA1541A Dac. I've seen references to:

- Silicon Carbide Shottky's like CREE
- Regular Silicon Shottky
- Harris FRED
- HexFred
- IXYS, including HyperFred

Anyone upgrade their standard soft recovery diodes with one of these with clearly improved results?

I'm looking for more resolution/detail from my TDA1541A NOS dac.

Finally, anyone care to recommed the same for my DRD300B amps?

Thank you!

Hello Mike,

Actually I haven't encountered Schottkies that sounded worse than regular silicon.

Types I use often in my modules and modifications are:

SS16 (smd)
D15XBS6 (15A/60V bridge from Shindengen, great company)
SB160 (1A/60V wired)
SB360 (3A/60V wired)

Another advantage of SB's is lower forward voltage drop hence less heat development.

best

Guido
