Mark Levinson unveils No 523 preamp and No 534 power amp

Latest duo promises uncompromising performance

Mark Levinson has unveiled two new designs, which can either be brought separately to expand your system or as a pair to create an exceptional pre-power partnership. The £16,000 No 523 preamplifier is claimed to deliver an uncompromising performance regardless of analogue source and comes equipped with a Class-A phono stage, Class-A main drive headphone output and discreet balanced R-2R ladder volume control. It boasts five line-level analogue inputs, two balanced XLRs, three single RCA stereo outputs and a phono input with earthing post.

Meanwhile, the No 534 (bottom in pic) dual-monaural power amp delivers 250W per channel (into 8ohm) in Class A (doubling to 500W into 4ohm). Balanced and single-ended inputs plus four pairs of gold-plated binding posts make up its connections. Both are available in the UK from Karma AV or visit for more info.
