I used to have an Orefeo SET 40. It is a very good amp and the 845's are one of my favorite tubes. The Orfeo is a special version which is beautiful....same amp just different cosmetics. I currently use a pair of Komura SET 845 monos which are better in all areas but very hard to find and 2-3x the price. Your ultimate enjoyment of this amp will depend on speaker interface and personal preferences. Please e-mail if you have additional questions kglide3@aol.com
