Bass leaves after amp warms up?

I don't know as much as many posting here, but the amplifier/speaker match always comes up sooner or later when we know speakers aren't playing up to their potential especially in the bass. I've always seen in the forums that proper matching of the amp/speaker is crucial to proper performance. Sounds like a bad match between the Synchrony 1's and the Musical Fidelity amp. You may want to try a high current amplifier that "doubles down." (the power of the amplifier doubles as the impedance of the speaker is halved). By the way, Bryston and Musical Fidelity amps do not do this.

I go back to my original assertion. As Almarg says the results suggest that these amps could not hack it with these speakers (not a good match into a 4 ohm load). I would look at trying an amp with the PSB'a that doubles its power into 4 ohms. (high current)

Heyraz, I can understand how you might take Csontos' post the wrong way taken out of context, but in context it was actually a harmless joke.
This thread as a whole is a great example of audiophiles and audiophile forums at their best. A very special thread indeed.

The spirit of assistance was strong in this thread.
