Bob...you could definitely upgrade the cartridge. The 10X5 is pretty decent, but there are better out there. If you like the Dynavector sound, (I really do, one of favs), I would recommend a 17D2MKII or a 17D3.
Also, if you still have the original HW-19MKII platter, you could replace it and really improve things. I think the TNT MKIV platter is the best and I've owned ALL of the various platters. A Super Platter is better, but they are almost impossible to find in good condition. I have tried the new metal platter and IMHO, still think the TNT MKIV platter is better, (on a HW-19). I know some disagree with this, but that has been my experience. YMMV.
Also if you could find a HW-19MKIII stainless steel and acrylic plinth, they are best sounding of the bunch, but again, some of these parts are getting hard to find.
In addition if you are still using the original suspension, try to find a set of (4) SIMS Navcom Silencers. These work really, really well and sound incredible. Make sure you remove the outer steel bands. Tiptoes for feet are another pretty decent tweek for not a lot of money.
As you can see, there are a lot of things you can do to a HW-19 table. I've done it all on many, many different HW-19s and still think this table is a keeper. Probably the only people that know this table better than me is VPI.
