I have two of these units now and only need one. For anyone who is considering purchasing this I highly recommend it, this is an awesome digital preamp/ analog preamp/ headphone preamp/Stello U3/ DAC (Digital to Analogue Converter). You will be hard-pressed to find anything that will outperform for the money. Includes box, manual, power cable, and an unopened/unused USB-USBA cable as well as the CD with the driver for windows OS machines with USB 2.0. You can rip your vinyl to 24 bit 96 KHz if you have a good ADC (Analogue to Digital Converter) and the appropriate computer software, then store them on a large hard drive and play the files in 24/96 on your computer through the Eximus DP-1's DAC and built in Stello U3- via the USB-USBA cable. This was intended for a second system but I am no longer going to build the second system. My loss is your gain these retail at $3200 now... Thanks for looking and I look forward to hearing from you and doing business at this unbelievable price :-) I added in some size and weight into the shipping dimensions assuming that the purchaser will want it double boxed for shipment.
