Calloway, I certainly have not heard a large range of amps on my Contriva Diacera SEs, but I was both very unimpressed and very impressed with the BAlabi BP-1 Power amps on Tidal Sunrays. The first be in CES 2010 and the second in CES 2011. Perhaps this was the difference between the Mk I and Mk II. I bought them having heard them on the Ypsilon prototype DHT mono SET tube amps using the Russian GM70 tubes with their present PST 100 preamp. This was overwhelmingly good in my opinion and lead directly to my buying the speakers. I don't remember what the power of these tube amps but with this tube it should be over 30 watts. I have also used the BMC Amp M1s that do 200 watts into 8 ohms. I wanted to get the Ypsilon Aelius hybrid, mono blocks with 220 watts into 8 ohms but could not afford them. I have been very happy with the BMC and they are still getting better. Finally, I heard the Tidal electronics on the Tidal Piano Cera speakers (I think). They sound was okay.
I think all of these experiences make believe I will live with the BMC as still getting better.
