First I would check and make sure your amp and preamp are working properly and no tubes are defective. Also, make sure you are not getting any bad power spikes or RFI problems. I am not familiar with your speakers. I have a Bel Canto and have found that with the wrong cables and transport, it can sound closed in or bland. If you are using the power cord that came with the Bel Canto, suggest you replace that with almost anything else. I had to experiment for awhile until I got a combination of cables that worked best. Also, the Bel Canto takes a few weeks to settle in. I am not convinced that a DVD player is the best transport to use, but rather than get rid of it, a cost effective upgrade may be to get a used jitter reduction device.
