Boulder 508

Boulder 508 phono stage

Very good condition Boulder 508 phono preamplifier.  This is one of the most well reviewed preamps on the planet under $10k and mates well with most MC/MM cartridges.

This unit was originally a showroom demo unit, then sold to a client of mine.  That client traded this unit in on a CH Precision P1 (which costs 6x this unit).  We upgraded the OEM footers to RevOPod mini which will be included with this unit (but are not pictured).  This comes in the original box with owners manual, power cable and XLR to RCA adapters.  It has cosmetic imperfections, thus the 7/10 rating.  There are a few marks on the unit all very small - one on the front near the mute switch and 3-4 more very small imperfections on sides and back.  If you want great sound, get this - if you want cosmetically perfect we can order a brand new one for you at MSRP.

Note:  this unit has XLR outputs ONLY.
