Your room is probably your weakest link, the component that is by far the least linear in your system. It is has long been known that room correction can improve bass and midrange dramatically. The $1099 DSPeaker Dual Core 2.0 does room correction up to 500 Hz, simply and easily, with a microphone that is included. It also has inputs for USB and SPDIF, and a great sounding DAC. In addition, it has a remote volume control, so it can be used as a pre-amp. It is a terrific product. Contact Jeff Stake Hi Fi at 812-345-5733 for a demonstration in Bloomington Indiana.
