Has anyone listened to this preamp. It used to cost $2000 but now only cost $800. I am tempting to buy it to hook it up to the B&K amp. I'm using the HK 630 receiver as a pre-amp now so I'm wondering how the HK compares to this Boston gear? Does the Boston sounds superior to the HK or there is not much of an improvement?
Or should I just wait for a discount on the B&K pre-amp?
