Sounded very detailed and clean, but extremely polite and with limited dynamics and bass was missing as well. The amp was not able to properly push them I suspect. I was also worried about longevity as they had a repair job on one of the transformers.
I got some Cardas GRFA RCAs for my DAC and amp and they work just fine. My friend had no problems with soldering them and I have used them for more than a year now with no problems. Nothing scratched off and they look like new.
