Perreaux SM6 MK II Silver class a fully balanced preamplifier

I am using this preamp in an all analog system with spectacular results. This is one classy looking preamplifier and ideal for those who are predominantly Analog based.
This has been my Demo Preamplifier for a couple of years, it is in excellent shape and sounds great. I am going to rate it an 8 of 10 in case there are some marks I didn’t notice The SM6 MKII posses the classic beauty of high end audio and the neutral sound which defines high end audio. Partner the SM6 MK II with the Perreaux 350 stereo power Amp or if you really want to go for truly unlimited power partner it with a pair of the Prisma 750 mono block power amps. They have that classic timeless beauty of some of the worlds best built and best sounding electronics. General Features True balanced input and output for improved noise rejection and cancellation The SM6 MkII is a fully balanced stereo preamplifier, from input to output. The positive and negative halves of the signal never touch. This is very rare and only the highest quality hi fi audio preamplifiers have this architecture. Four discrete line stages running in Class-A The Class-A line stages have been designed to provide output buffering, so the user can drive low impedance loads over long cable lengths using any cable, without affecting the quality of the audio signal. Six separate regulated power supplies There is a separate power supply for each section of the preamplifier; one for each of the volume control ICs (one IC is used for each of the left and right channels to keep the system fully balanced and, therefore to maintain separation each IC is supplied with it’s own separate power supply), another one for each of the output buffering stages (once again because the SM6 MkII runs a fully balanced system, this means that there are two separate output buffer stages), yet another to power the digital logic and the final power supply looks after the input and output relays. The advantage of is that there is complete isolation from stage to stage, and most importantly digital noise is completely kept from infecting the analog audio section. Wireless remote control of all functions Many audiophile hi fi audio components are still provided with analog controls that are adjusted on the faceplate of the unit. While total control from the remote is common practice in standard products, it is not yet widely utilised on many high-end audio systems. Obvious advantage is that you don’t have to get out of your chair to make an adjustment. Home Theatre Bypass The SM6 MkII features a direct input (processor loop), which bypasses the preamplifier for use in a home theatre system. Earthing We pay particular attention to designing the product to ensure maximum separation between internal signal and power earths, only meeting at a central starred point. Premium grade components used throughout Wima signal capacitors, custom wound multi tap epoxy potted toroidal control transformer directly soldered to the PCB, highest quality fiberglass PCB allowing special treatment to be given to earth planes and layout with minimum dielectric, hand soldered through-hole mounted components. Precision digitally controlled analog resistor ladder volume control The SM6 MkII uses two digitally controlled resistor ladder volume controls. This is because we treat the positive and negative parts of the signal separately (true balanced system). The advantages of using a digitally controlled analog resistor ladder to adjust volume are - precise control, no contacts to corrode creating wiper noise and no analog component drift. Input switching via high quality relays Any manufacturer who uses a comprehensive remote control will use relays. However, Perreaux employs the use of high quality relays with gold plated silver contacts, thereby further lessening the chance of degrading the audio signal. Dual preamp level outputs You do not need to purchase an RCA style splitter if you want to drive two separate audio power amplifiers simultaneously (for example in a bi-amp situation) or if you wish to include a subwoofer in your system, as there are dual preamp outputs. High quality PCBs Quality PCBs featuring heavy copper tracks and components are used throughout the unit. Remote Trigger Outputs Dual 5V remote trigger outputs are provided to allow connected components to be powered ON or OFF as the SM6 MkII is taken in and out of standby. User Controls Infrared (IR) Remote Control Alphanumeric Display Simple User Interface Remote Trigger Outputs Balanced/Unbalanced Selector I/O Compliment 6 pairs Unbalanced Inputs (RCA) 1 pair Balanced Inputs (XLR) 2 pairs Unbalanced Preamp Outputs (RCA) 1 pair Balanced Preamp Outputs (XLR) 2 pairs Unbalanced Line Outputs (RCA) The remote control will impress you and your friends as it must weigh 2 pounds.

I am not offering any returns at these reduced prices if you wish to be able to return the unit you should buy direct from Perreaux at full Retail, www.perreaux.com
I am a full line Perreaux dealer so if you want a model you don’t see advertised on Audiogon please contact me.
These are all great sounding products that last forever, I get calls almost everyday from people who have owned thier Perreaux amp or preamp for 20 years and just want to get it brought up to it’s original specifications because they love it so much.
Please write or call if this is of interest to you.
