My reference audio system at Parmenter Sound consists of the following audio equipment. EMM Labs CDSA CD/SACD player, Lamm LL2 Deluxe preamplifier, Wavelength Cardinal 300 B mono block amplifier &the stunning Avantgarde Acoustic Duo Omega speakers. Interconnect & speaker cables are the Nirvana Audio S-X Ltd. Power conditioning is by Equi=Tech Q2. This audio system has a synergy & musicality which really has to be heard to be fully appreciated. Next step is the Lamm ML 2.1 power amplifiers in the mix. Thank you for letting me post my audio system & I hope this helps other Avantgarde speaker owners to build audio system synergy. Kind regards Jason Parmenter.
