I have a MiniDSP 10x10HD I would like to sell. I purchased it to Bi-amp my Belle's but the Belles are to sensitive (105 db) to work well with the MiniDSP. However the software was easy to use and it worked very well as a DSP and as a 3-way crossover. It acts as a DAC and a pre-amp with both digital and analog ins and outs. Very versatile, I was able to incorporate REW into a vintage McIntosh 2 channel system and was able to adjust for my Tuba THT sub. Including time delays and crossovers for each output. I have the box and all of the original contents for $500 and I'll split the shipping with you (CONSUS). This item was $600 new and took 2 weeks to come from Hong Kong. Thanks for looking.
