Absolutely love my Decware 341.5. I’ve rolled tubes and the improvement is awesome. I do recommend that you upgrade the caps. I did and wish I had upgraded to the Vcaps. I feed the amp with the Brinkmann Nyquist DAC. Really go well together. The amp seems to drive any speaker with sensitivity above 87. I’m running Lii Audio speakers with a 98 sensitivity. My biggest decision is finding a preamplifier to maximize the benefits of both the Decware and Brinkmann. The journey continues.
