If this were me, I would save until I bought a Basis 2000, and then skip the Glider altogether. I would look for a used Basis, with Graham arm (ok, this is me next year, perhaps). I have the Lo4 with my HW19jr now, and the improvement over the Glider HO I had belied the difference in price. The new Glider might be better, but it won't be a Lo4. By that time, you could also get an outboard phono stage that would power a medium output cartridge like the Lo4. The Glider was sluggish and unrefined, compared to the Lo4. For the $$, the Blue Point Special is a terrific buy (I had one of those, too).
Cartridge suggestions
I'm anxious to get back into vinyl, but I have to take it a little slowly for now. I was just given an old JVC turntable. This is temporary. I was thinking about getting a new cartridge and then having it put on the new tonearm and turntable once I upgraded. I have my eye on the Rega 900 tonearm in the future or maybe the JMW Memorial and a Basis 2000 or one of the VPI's. I don't know very much about cartridges. The Benz Micro Glider has been suggested to me. Any suggestions on selecting a cartridge? I have an Audible Illusion Mod3A without the upgrade phono stage so I need a higher output cartridge. I feel I know just enough at this point to get myself into trouble by picking the wrong one.
