This is an all black wired only (for stability) RWA modded SB3. I have heard a variety of squeezeboxes and DACs, and this is my favorite. I still use a SB3 w/ identical RWA mods in my main system. The following mods were done:
1) replace dac chip to "KE" version of the PCM1748
2) installation of new RCA jacks...gold plated with teflon insulator
3) hard wire output of dac to directly to new RCA jacks via
Auricap signal capacitors.
4) Replace stock analog power supply cap with low ESR Panasonic FC type
5) Replace power supply decoupling caps to the dac with Black Gate NX-Hi-Q caps.
This SB3 is in very good condition except for one blemish, there is a small mark on the left side of the case where it appears to have been touched w/ a soldering iron. Beyond that the only cosmetic issues are a few faint scratches in the rear.
Accepting Paypal Gift, Paypal, or USPS money order. Will be shipped double boxed and comes with SB3, remote, and power adapter. I have feedback on Head-Fi and Audiogon. For sale in the US only.
