AI L1 sound better than AI M3?

Cytocycle is right the L1 -3 have dual amp outputs 1 is buffered also the aux is the best imput, the cd is buffered?I think. took me awhile to remember .I could be wrong been awhile since I owned the L1.JK

There were updates to both which you can tell only by comparing the dates on the circuit board inside. But I doubt very much that's what your hearing. First the tubes must be upgraded if you want to perfect the sound. Kevin Deal at Upscale Audio has 6H23 best quality tubes which you can purchase-best bang for the buck still $30@. NOS could be better but expensive and life will be shorter. Next for for CD use aux or tape, but never CD which hasbuffering.

Thanks to all for the responses. I actually called AI and they said that my ears were not deceiving me; the L1 sounds better than the M3 and the M3A sounds even better than the L1. Now I have to decide whether to upgrade to the M3A. I'm also thinking about just buying a Conrad Johnson EV1 and running it through the L1. Any opinions on whether that would be better sound than the M3 or M3A? BTW, those dual volume knobs are driving me CRAZY!

thanks,

Wouldnt know about the sound of the M3A but I replaced my L1 with a Art Audio MK2 Preamp and it was much better sounding and very flexable compared to the L1 ,JK

Just curious Johnk, what was the price of your Art Audio preamp? Thanks.
