I have the following two synergistic for combo sale only (may split if combo doesn't sell): High resolution and powerful DIY Butte HP amp designed by Pete Millett and based on the $450 Apex Butte. Made by me. Comes with Triad power supply and 1/8 to 1/4 adapter. Needs about 30 seconds to warm up after power on. Starting Point Systems DAC 3 USB/Coaxial/Optical up to 24/96 TDA1543 NOS DAC. USB powered and comes with 6ft USB cable. No Windows drivers needed. Custom made (made by me) RCA cable set. Approx. 5" inches long, cable made of ViaBlue cable with black/red parachord sleeves and Switchcraft RCA connectors. Perfect length between the Butte/DAC3 stacked or side by side. Very compact size and sound wise, these two compliment each other in a extremely nice way. Split the two if desired, but sound best together, IMO. Combo price at $199 and includes PP fees. Split shipping CONUS based on 4 pound box.
