Looking for a change.

As expected the common theme is the Yamaha. I have a friend who is a Macintosh dealer and has been pushing me towards a Macintosh. Of course I could demo at home as long as it's in stock. He also has Prima Luna, which I know a few people mentioned tubes. I've also come across a Rotel RB 1590 which I would use as a external amp. I will begin seriously considering moving on from my Yammie, as the main power source, it has served me well.

I've enjoyed reading your comments and perspectives. Some have asked about my equipment, if you read my original post it's all spelled out there. Some have suggested brands that I would consider a lateral move not a move up. As far as my cables and room, my interconnects are mostly Audio Quest, except the subs which are SVS cables. My budget is not a problem since anything I purchase I will probably get a good deal with my connections through dealer friends. My phono amp is a hybrid tube, I would consider a tube integrated and I do have a Prima Luna source. My musical tastes are anything from early jazz to classic rock and a lot in between. My room could use help, but since it's acually a part of my house, changes can be difficult. Dimesions are 17x15 with vauled ceilings as high as 16 ft. and open on 2 sides. It's carpeted and furnished but I assume the ceilings are an issue. Someone made a comment about power supply and that made me think. Should I consider a power conditioner and power cords before I make changes in my integrated amp? Do power conditioners really work and are they worth the money? Right now everything is just plugged into a power strip then into the wall.
