I finally got around to ordering it. Delivery will be around the end of OCT. According to Frank it will elevate my 2 channel listening enjoyment to a whole new level. At present I am very delighted with my 2 channel performance. But I am always looking for ways to improve without having to take out a second mortgage on my house. LOL!! Hence the need & curiousity to try the Ultra DAC to hear what it will add. Frank is very confident in his products & offers a generous return policy. If it's anything like his OmegaStar 440EX amp that I own, I'm sure it's going to be a keeper. Only time will tell!!
