Hello all, First of all, I´m selling this because I need more inputs. Most likely I´ll be buying an NFB-8 to replace it. This is the "S" version of the Reference 7, in other words it only accepts a single coaxial or BNC input. The ideal pairing is with a CD transport or the Audio-gd Digital Interface. The DSP-1 has been upgraded to version the latest version, V5. The stock wires have been replaced by DHC Nucleotide OCC copper wire at the Audio-gd factory. The unit was bought around last september. Only offers from inside the EU will be considered, as taxes etc have already been paid once. I´m pricing this to sell: 1200 euros including shipping inside EU. I reserve the right to choose the buyer according to trader feedback etc. If you are interested, I can also sell the buyer an Audio-gd digital interface. Item will be shipped in the original box Audio-gd used to send it to me, so it´ll be a safe trip! If you are interested in a trade, here is a list of items I may be interested in: solid state Stax amplifiers, Benchmark DAC-1 PRE or HDR, Wyred4Sound DAC-2.
