Running Speakers with amps of minimum output
I have recently changed my speakers from 94db Living Voice Avatars, to 89db sensitivity Acoustic Zen Adagios. Now both have a good benign impedence profile, but the Lavardin IT I am using with them is at the recommended lower power output required by the Adagios, 50watts. Now the Lavardin is everything that has beem reported about it, neutral, clean, with no hash and dynamic. It sounds very good with the new speakers, but I just wonder what I am missing, presumably, some base grip and drive, which will affect the higher frequencies. Certainly I notice a bit of congestion in busy orchestral music.
The recommended output requirements for the Adagios is 50 to 200 watts and I know that is only a guide. As I intend to stick with the speakers indefinitely, I was wondering what SS integrated around 150 to 200 watts, of a similar quality to the Lavardin I should be looking at. Two immediate thoughts were the new Conrad Johnson CA 200, which I have'nt heard, but I like CJ, also the Karan KA1-180.
The rest of the system is Origin Live Resolution/Illustrious/ koetsu Rosewood Signature
Modded Shanling CDT 100
Viva Solista 845 SET(for winter central heating)
Acoustic Zen cables
I listen to Classical, opera, Alt country and Singer Somgwriters, Jazz and Blues.
Any thoughts on the general question of matching amp output to speaker sensitivity and particular amp recommendations, would be welcome.
