Twl, one word. Fabulous. I may upgrade to this config eventually before a table upgrade (Spacedeck/Spacearm/Shelter 501). I am not fully convinced that the extra bucks for the 901, as opposed to the 501, is justified in all cases, however. While the 901 was outstanding there is a certain richness to the 501 that is hard to put into words. If you are into solo stringed instruments or piano and/or small ensemble-type groups of any kind, the 501 might be all you'll ever need. I am half tempted to buy another in the event they ever go out of production! :-)
As aside, I did a comparison of the 501 to SEVERAL other cartridges (most costing MUCH more) at the same shop mentioned above before opting for the 501 for my table.
OK, I knew I couldn't make a post with just one word! HA!
