Bel Canto System

Selling my Bel Canto components. I am changing over to an headphone only system so starting from scratch.  I'll sell these items as a group or individually.  See my other listings if you want to buy only part of it. 
Pair of Bel Canto REF1000 MKII mono amps.   I've had them since 2011 and so they do show a bit of wear.  There is one tiny nic on on of the faceplates as shown in pic.      
Bel Canto e.One DAC 3.5VB D/A Converter with VBS1 Virtual Battery Power Supply and upgraded VBREF umbilical cord. This is a stunningly quiet and musical DAC.  These units were purchased brand new in 2013 or 2014.  Only have one of the original boxes, but do have both manuals.  I will package both units in one large box and include appropriate packing materials.  

Bel Canto RefLink Asynchronous USB Converter.  Purchased in 2014.  I am including a nice ST-Fiber cable that was purchased separately.   I used the RefLink with my 3.5VB/VBS1 DAC combo connected to a Mac Mini with most excellent results. 

I've been traveling almost non-stop for my work over the past four or five years so they haven't been used much, but prior to that I'd say about 20 hours per week.

High performance Asynchronous ultra-low phase noise USB link connects your computer to your audio system with complete isolation from your computer source.

• Ultra-Low Phase-Noise Clocks


• Ultra low noise internal power


• Operate at 16- or 24-bits at 44.1, 48, 88.2, 96, 176.4 and 192kHz


• Proprietary 500MHz DSP Core


• MAC USB 2.0 compatibility and custom Windows USB 2.0 driver 
  

Asynchronous USB
With a true Asynchronous interface our Ultra Low Noise Femtosecond Master Clocks control the output jitter from the computer source. This provides the lowest noise digital source for the system DAC and unprecedented sonic transparency from any source file.

3 stage Galvanic Isolation
The REFLink ensures complete isolation USB born computer noise by the use of 3 stages of galvanic isolation. This insures that your audio DAC is never effected by computer based USB born noise keeping the entire dynamic range intact.

Hybrid Distributed Power Supply
Ensures that the Ultra Low Noise Master Clocks perform to their potential with power supply isolation and local low noise regulation right where it is needed.
