Make sure the belt is good, and clean the RCA connectors real well. Get a cartridge alignment protractor for $20 from turntablebasics.com and make sure the cartridge is aligned properly. Make some minor adjustments in the tracking force and anti-skate and listen to see if things get any better or worse, and try to find the best sounding setting. Put the TT on a dedicated stand that is lightweight and rigid, with no other equipment on the stand with it. If you can remove the dustcover, remove it totally from the table when playing.
Wow, I really prefer the 1300. Try your Shure on the 1300 and see what you think. The plastic headshell carrier and very light arms on the Duals can be a bit of a problem. I've got a weird one. I hope that Tom (above post) isn't reading this. Perch the table on three drinking glasses that are turned upside-down. Really, try it, I'm not kidding. The 701 is a direct-drive, no? In which case you wouldn't need to worry about changing a belt.
Marty, does it help if you empty those 3 drinking glasses of a fine single-malt Scotch whisky before you put them under the table? :^)
I didn't know if the Dual 701 is direct drive. Sorry if I was wrong about that.
I take it you are serious about the 3 glasses? Just curious, what is the purpose of removing the dustcover? Vibration? Thanks for your help. I live in a part of the country that no one carries mid or highend analog equiptment. So this is all new to me. I have collected and listened to vinyl for the last 12 years, but the thought of getting a much better sound intrigues me. I have been reading alot also on the Disc Doctor. I think I need to invest in a better way to clean my records, as apparently there is a much better way than what I have been doing. Thanks for your help!
I wouldn't recommend spending any money on a tweak that couldn't be transferred to another table sometime down the road. In fact, at this point, I wouldn't recommend any money-related tweaking at all (e.g. ringmat, new conterweights, dedicated tt stands, etc). Having said that, investing in a Shure traking force gauge (20$ from audioadvisor.com) and getting a free alignment protractor (http://www.enjoythemusic.com/magazine/equipment/0900/protractor.htm) and then reading up on alignment techniques and then fiddling with alignment may help. Try to isolate your tt from vibrations and movement, but try to do it as cheaply as possible (i.e. a piece of mdf attached to the wall w/ shelving brackets). Spend your money on cleaning the lps you have (perhpas using a homemade cleaning recipe--there's plenty of ideas on the web) and putting them in new sleeves. Add a good, cheap carbon fiber brush like the Audioquest one, and you're good to go. Enjoy!
I would post this question in (www.zero-distortion.com). The editor is very knowledgeable (and still uses) on Dual DDs.
If you want a highly cost effective "upgrade," I suggest the Disc Doctor (DD) cleaning system of which you seem to be already aware. The DD approach to record cleaning is simply outstanding. The method invented by DD allows maximum cleaning, minimal expense, and efficient use of time. I have recently cleaned LPs on my VPI HW-17 Vacuum Cleaner using Record Research Lab cleaner. Then I have cleaned using DD cleaner and scrub brush. Foreign matter had caused the LP to skip in places AFTER being cleaned on the VPI, but the skips disappeared after cleaning with DD. The DD felt scrub pads seem to get into the grooves to thoroughly clean. Also, the sound of the LP has a richness not present before using DD.
The VPI HW-17 system is convenient, but not nearly as effective IMHO. Since I have been using DD for only a few days, I am now in the process of rewashing my previously cleaned LPs. My TT, a VPI HW-19 (MkII) with JMW tonearm and Shelter 501 cartridge, has never sounded better. The results of sound quality improvement are most gratifying.
Thank you to all that responded. I have not had the opportunity to try any of the suggestions listed, but I hope to this weekend. I seem to think the best thing I can do, is get the grooves really clean. Your help has been appreciated. Thank you!
Viridian & Psychicanimal,I am on your side this time.
I don't like the 501.
I think Viridian & Psychicanimal Know how to tweek a 1300 that will kill a 501.
Ok, this weekend I have had the opportunity to hook up and listen to both TT's in question. I used the new Shure VN 35 on both and after listening and trying to compare, I think I like the 1300 the best. I still need to get a Disk Doctor and get busy doing some serious cleaning. Thanks for all or your help. Much appreciated!!!
Ok, now that we have settled on the Technics are we ready to tweek our hearts out? First order of business is to make sure (pun intended) that the table is perfectly level as, unlike the Dual, this is a static balance arm. Also be sure that the cartridge is properly aligned and the tracking force and anti-skate are correct. Once done we can move on to the more....esoteric stuff. In order of cost, free being first. Try the drinking glasses, really. Next, you will notice a little rubber washer on the collet of the headshell. Try removing it and listening to the sound. You can always put it back if you don't like it. Also, take a couple of trashed records, one thin like a Columbia and one thicker, and then cut a piece of cardboard the size of a record. Now you have three thicknesses. Try each one between the mat and the platter and listen to a familiar record. This changes the VTA, or the angle at which the stylus meets the groove. At under $20.00 there are some nice replacement headshell wires available from Audioquest and Sumiko. I's surprising how much of a difference this can make. A set of tiptoes or vibrapods replacing the stock feet will make a difference but, better or worse, who knows? But at around $25.00 may be worth playing with. Ditto for a better mat. Audioquest makes one that can be purchased used on this site as well as the Ringmat. A new cartridge may also be in the offing. Grado makes some really lush ones starting at $40.00 or so list. If you like a leaner sound Radio Shack has the Audio Technica AT-120E for around $65.00. Most important though, buy vinyl, buy vinyl, buy vinyl.
Thanks Marty. I will start at the top and work my way down the list and will listen for improvements. I was wondering if you were serious about the 3 glasses, LOL, but will give them a try. As far as buying vinyl, I already have around 5,000 LP's and 10,000 45's, but am always keeping my eye open for more, just don't tell the wife I said that. hehehe
In the meantime, I will follow your suggestions and let you know how it goes. If you think of anything else, please continue. I am very green at all of this and am willing to learn. Actually, I am not really sure what collet on a headshell is. I do see a small rubber deal by the back of the tonearm, about an inch from the edge of the platter, is that it?
No Steve. If you remove the headshell there is a little rubber gasket or washer on the end of the headshell itself. When you slide the headshell into the hole at the end of the tonearm this little gasket is supposed to create a compliance between the two. Sorry for the confusion.
