I cannot comment on the RX505 as I've never used one. I'm sure it's a great deck, but it's limited in features for best possible recording and playback. I've had zero issues with people playing back tapes I've recorded on my Dragon. I've had many comments on the excellent sound quality of tapes I've made on my Dragon using inexpensive Normal Bias tapes such as Maxell UR's. These tapes were played on other high end decks from Pioneer, Sony, Revox, and Tandberg. The Dragon is also the best playback deck made. With the auto azimuth, auto reverse, quartz locked dual direct drive capstans. The CR-7A, Cassette Deck One, and DR-1 feature user adjustable azimuth knobs.
