I own a Simaudio LP5.3, a Violectric PP1 (can't believe someone else mentioned it-I thought I was the only one on the planet to own one), and a Manley Steelhead. By and large, I think that you can pretty much tell which phono stages are going to have the qualities that you refer to as "balls" by looking at the power supply. If it is huge, such as found in upper tier BAT or any Lamm or the TW Acoustics referred to above and the Steelhead, chances are pretty good that you will get those qualities. The power supply is the magic ingredient not only with phono stages but preamps in general. Look at any top drawer preamp that has almost universal acclaim and it is virtually certain it will have either a huge separate power supply (e.g. the ARC Ref 10) or a large internal power supply (which is second best).
