Guys, thanks for all your great suggestions. I live in Puerto Rico and finding a good electronics technician is becoming a pain in the a$$. Prior to trading had the McIntosh MX-113 Pre serviced by the best tecnician in the island, Lamda Audio, but he is so full of work that he is lacking in taking care of details, he just fixes what you tell him the issue is and is not inspecting the whole unit as to verify for other issues. Right now I am taking to him the MX-113 to be cleaned and to have a channel checked. It is making scratching sounds, and even though I'm pretty sure it is a cleaning issue (deoxit) there might be something else that he would have caught if he checked the unit in general. I told the new owner of the MX-113 that I would take care of that. Tube amps, specially point to point, I can repair with my cousin's guidance, but SS is another thing.
So, after loosing a bid for a Creek 5350 SE modified by Hot Rod Audio, I decided to go the new route. I checked NAD 3045, Denon PMA-800NE, Rotel A11 Tribute, and Arcam SA-10. Finally, I decided, as always, to stretch my budget (got a good financing deal of 6 months to pay without interests) and pulled the trigger on the Arcam SA-10.
