I had McIntosh amp and preamp in a large living room. I had excellent sound. We sold the house and the McIntosh gear. I now have a dedicated 18 x 12 music room. I purchased a Luxman integrated. I was prepared to have downgraded sound because I went "integrated". I was very pleasantly surprised, the Luxman gave me better sound. (I know different room, different speaker placement) but none the less, better sound, and excellent features on the Luxman. I also have the option to use the "separate" feature on the front panel and remote and use the Luxman as a dedicated preamp, if I wanted to buy a new amp.
Bottom Line... Integrateds can provide excellent sound!
