I sold my GTP 740 and got the 970. The Adcom 740 was notorious for problems from the start so I was glad to get $250 for it. They may have improved their Preamp Tuners but I wasn't going to take a chance on them especially for the price. It looks as though Adcom has gotten their act together with a new website and some new "receivers" that will hopefully work out well for them. What's ironic is that I have an original brochure from around 1985 with a headline that reads "The End of the Receiver".
Looks like they've given up on that idea 20 years later. It doesn't seem like their Preamp tuners were very popular. If I didn't get the Outlaw, I possibly would have gotten a Rotel. Again though, it was twice the price.
