SparkoS Labs SS3602, MUSES02, OPA2134PA, High Quality Operational Amplifier Chip for BT20A PRO and V3 (1 Pair 2PCS)

purchased the BT20A Pro couple of weeks ago with the 48v GA PSU to replace my old BT20A amp. After I received it, I connected it to my new KEF R3 META speakers. When I play it, the amp gets really hot quickly and the speaker stops outputing any sound within 20 mins. Few days later I received the SparkOS op amps, i rolled them in. The problem still existed. After working with your support team, it turned out the unit is overheating and thus the heat protection mechanism is being triggered. When I replace the PSU with a 24v PSU, the problem disappeared. It does not seem that the amp works as advertised that it works with a 48v PSU. Finally your support team agreed to refund me for the 48 GA PSU and send me a 32v PSU to use with the unit. This is why I am giving you a 2 stars. The sparkos opamps sound good when the unit works.

Relativ schnelle Lieferung,
Schnell in ZA3 montiert. Ich persönlich höre kein unterschied. Man kann sich sparen.

The MUSE02 operational amplifier chips make the BT20A such a joy to listen to. Great clarity is similar to the stock chips but sound is less fatiguing over time. Beautiful to hear old music like it was the first time again. Thank you!

I must admit that I am a big fan of the sparkos 3602 opamps, I have installed them in my V3 Monoblocks and can really hear the improvement in the sound
I am really happy with my purchase.
Thanks to Fosi, Audio, keep up the good work.
