Hey Larry, I just installed a new 103 (couldn't swing the extra $90 for the R) on a DIY TT project two days ago. I agree with HDM that after about 15 hours, four of which were run on the Cardas burn in disc, the 103 REALLY smoothed out and started to sing. It may be one of the biggest bangs for your audio buck today. This project is putting out some serious sound. Let us know how your 103R sounds over time.
