Description
Extremely rare sut made in England for highend step up MC cartridge. Wonderful sound. From my highend collection. The AN-S2 is a passive device, designed to convert the mainly current output of your Moving Coil cartridge (MC) to a higher voltage, low current signal of sufficient strength to allow a Moving Magnet (MM) phono stage to amplify it to a suitable level. The internal transformers used in the AN-S2 are manufactured by Audio Note (UK) exclusively, use the very best core materials and winding technology available at the price, and are housed in mumetal screening canisters to minimise noise and interference. The AN-S2 can be supplied in two versions; the AN-S2/L (low impedance) and the AN-S2/H (high impedance). The ‘L’ version has a switchable input impedance of 3 Ohms and 12 Ohms; the ‘H’ version, 15 Ohms and 60 Ohms. The 3 Ohm input of the ‘L’ version has been primarily designed to partner the Audio Note IO Moving Coil cartridges, and the 12 Ohm input is intended to be used with cartridges with an internal impedance of around 3 to 4 Ohms. The 15 Ohm input of the ‘H’ version is designed to partner cartridges with an internal impedance of around 4 to 5 Ohms; the 60 Ohm input is designed for cartridges with internal impedance in the region of 15 to 20 Ohms. It is possible to use our transformers with cartridges that have greater internal impedances, or values that are outside the preferred ranges of the switchable inputs, however, it is important to realise that an input impedance in the region of three to four times the internal impedance of your cartridge will usually provide the best results.

Description
Up for sale is one modified Denon AU-320 Phono SUT in very good to excellent condition. Ratios: 1:10 (40 ohm setting) PASS (pass through for MM carts) 1:36 ( 3 ohm setting) This SUT has been modified in the following way. First, the tethered stock cable was removed. Second, the L and R output signals were rewired to the pickup-2 RCA jacks. This was done in order to eliminate the umbilical cable and more importantly to use whatever desired interconnect cables to the phono preamp. Because of this mod, the 1 / 2 switch does not function and the SUT can only be connected to one turntable at a time. Additionally, the 3 / Pass / 40 switch was disassembled and thoroughly cleaned with Deoxit. The switch retains its full functionality and acts normally in all three positions. The interior was cleaned and the exterior shell was sanded and painted Charcoal Grey Satin. The modified SUT can be returned to original 2 turntable operation if desired. To do so involves soldering, wire, and output cable. I have the wiring schematic for that and can provide it upon request. Additionally, the transformer can be wired directly to the RCA jacks to bypass the switch if desired. Contact me for details. I used this modified AU-320 with Denon carts DL-103, DL-103R, and DL-301Mkii and it worked exceptionally well. I upgraded my SUT to a Denon AU-340 and that is why I am selling the AU-320. Adult only operation in a smoke free home. I will ship usually within one day of sale using USPS Priority Mail. Please reply with any questions. Thank you.

Description
Extremely rare sut made in England for highend step up MC cartridge. Wonderful sound. From my highend collection. The AN-S2 is a passive device, designed to convert the mainly current output of your Moving Coil cartridge (MC) to a higher voltage, low current signal of sufficient strength to allow a Moving Magnet (MM) phono stage to amplify it to a suitable level. The internal transformers used in the AN-S2 are manufactured by Audio Note (UK) exclusively, use the very best core materials and winding technology available at the price, and are housed in mumetal screening canisters to minimise noise and interference. The AN-S2 can be supplied in two versions; the AN-S2/L (low impedance) and the AN-S2/H (high impedance). The ‘L’ version has a switchable input impedance of 3 Ohms and 12 Ohms; the ‘H’ version, 15 Ohms and 60 Ohms. The 3 Ohm input of the ‘L’ version has been primarily designed to partner the Audio Note IO Moving Coil cartridges, and the 12 Ohm input is intended to be used with cartridges with an internal impedance of around 3 to 4 Ohms. The 15 Ohm input of the ‘H’ version is designed to partner cartridges with an internal impedance of around 4 to 5 Ohms; the 60 Ohm input is designed for cartridges with internal impedance in the region of 15 to 20 Ohms. It is possible to use our transformers with cartridges that have greater internal impedances, or values that are outside the preferred ranges of the switchable inputs, however, it is important to realise that an input impedance in the region of three to four times the internal impedance of your cartridge will usually provide the best results. Technical Specifications INPUT IMPEDANCE: see text above OUTPUT IMPEDANCE: 47K Ohm CHANNEL BALANCE: +/-0.3dB INTERNAL WIRING: 99.99% pure Copper ?
