You're probably right. They probably won't sound any differently. But it would just make me feel better if Emotiva would just improve those numbers.
Now tell me, is that too much to ask from Emotiva?
Like say, "Could you guys do whatever it takes to decrease that crosstalk from -70dB down to -100dB, decrease THD from 0.1% to 0.004%, decrease the linear deviation from +/-0.5dB down to +/-0.1dB, increase SNR to > 100dB A, decrease output impedance to 10 ohms?
Do you think I would piss off Lonnie and Dann if I asked them that?
BTW, your Yamaha receiver has crosstalk of about -87dB, THD+N 0.008%, and freq resp of 20Hz-20kHz +/-0.3dB, which are excellent and better than the Emotiva RSP.
If I got the Emotiva RSP preamps, you and Greg would say that your Yamahas have better specs!
Now how am I suppose to live with that?
