Keis, I completely agree. The LS2B is, perhaps, the worst preamp I have ever heard. Painfully bright.
Just to show you how useless all our opinions are. I wanted something different than my Hovland, which I switched to after owning a ARC 5 for a few years.
My local dealer for Musical Surrounding's various lines, let me borrow a Calypso/Rhea for 10 days. I also brought in a REF 3/PH5 and went back and forth. Either would make me happy but, I preferred the ARC combo. Dead quiet with terrific bass authority. The real surprise, at least for me, was the PH5. What a unbelievable product for the price. I wouldn't say it was better than the RHEA but, absolutly it's equal.
