John Darko recently compared the LS-50 Meta with two different amps with the LS-50 wireless II system. Surprisingly, the wireless system did not blow away the separates system. He said that each produced different sound signatures but the differences were subtle.
The amps he used were: NAD. C326BEE V2 and the Hegel H95. The NAD configuration was a bit cheaper than the Wireless system while the Hegel configuration was a bit more expensive.
