I've been listening to this unit for a couple days now, and the improvement is quite dramatic. The sound stage seems deeper and wider on both cd and phono. Nice tight bass and more detail in the mid to high end. The phono section is much improved, with more definition throughout the range. Seems to be a good match to the Ortofon OM10 I'm currently using. This was well worth the time and effort, and the cost was pretty cheap even with replacing the relay, under $40. One word of caution. The subsonic filter switch is kinda delicate and comes apart pretty easy when manipulating the board around. Be careful not to bump it around to much. Thank you Leestereo for this wonderful mod.
