I'm currently powering my ESP-9s off of a Yamaha RX-V650 and I enjoy it but I feel like the low end is lacking and the overall presentation is thin. I feel like a tube amp would be a much better match for this.
Overall all I'm looking for something on the warmer side of the spectrum with decent power output so I could use it with speakers as well should I decide to do so. I was thinking a boyuurange A50 Mk III would be a good pairing since the 300B tubes are supposed to be warm sounding. What are your recommendations?
