Henley Audio have announced the return of two classic Musical Fidelity products. The M6 series is one of Musical Fidelity’s most popular product lines, but it has not featured a separate pre/power amplifier solution for quite some time. So, to address this omission, new owners Audio Tuning have ordered the re-introduction of the M6 PRE and PRX models.

The M6 PRE is a fully balanced pre-amplifier, with pure Class A circuitry with Surface Mount Devices (SMD). With two balanced XLR inputs and four unbalanced RCA inputs, the pre-amplifier also features a built-in asynchronous USB DAC capable of 24-bit/96kHz audio playback, and a switchable MM/MC phono stage. There is also the added convenience of a switchable RCA input for Home Theatre bypass. For connecting on to a power amplifier, the M6 PRE offers both RCA and XLR outputs, as well as a fixed Tape loop for other system solutions. Operation is via the front-panel buttons or supplied Musical Fidelity system remote.

The M6 PRX is a fully-balanced dual-mono power amp with 230 per-channel output (8Ω) it employs Musical Fidelity’s exclusive dual-mono, fully complementary, bifilar choke regulation system. Choke regulation is a concept taken from classic tube amplifier designs, but is rarely employed with transistor amplifiers. The M6 PRX’s audio circuitry is based on the classic Titan power amplifier design. It has eight output transistors per channel and has switchable XLR and RCA inputs, and it can easily be partnered into a bigger system via the RCA Loop output. Both are available from December in the UK. M6 PRE SRP: £1,899.00. M6 PRX SRP: £2,599.00. M6 PRE / PRX Bundle SRP: £4,000.00.
