Rega and VPI tonearm owners - READ THIS


I have just spent the past two evenings listening to a wide variety of LP's after installing Express Machining's "The Heavy Weight" counterweight on my Rega RB900 tonearm (which is mounted on a VPI HW-19 Mk 4 turntable, and has a Grado Reference cartridge). I was prepared to be disappointed, thinking that changing the counterweight on the tonearm would be, at best, barely noticeable. Holy mackerel, was I wrong!! This replacement counterweight is the best $80 addition I have ever made to my analog front end -- and if you own a Rega tonearm, you need to buy this gizmo.

The "Heavy Weight" replaces the standard counterweight on the Rega arm, and is also available for the VPI and AudioQuest tonearms. (I can't vouch for what it will do for the VPI or AudioQuest tonearms, but it made a major improvement on my Rega.) The "Heavy Weight" is made with its mounting hole off-center, near the edge, so that the weight hangs below the plane of the tonearm like the counterweight that's mounted on the end of railroad crossing barriers. The counterweight is secured with a set screw, unlike the standard weight on the Rega arm which is held in place by a rubber donut lining the mounting hole. The "Heavy Weight" is even supplied with a hex key that fits the set screw -- nice touch.

Folks, if my experience is representative, I've got to tell you that the improvement provided by this counterweight is NOT subtle. In addition to tightening up the deep bass, the modified tonearm yields better focus, imaging, detail, and the soundstage is deeper in both directions (both in front of the speakers and behind them). I know, I know, that seems like a ridiculous improvement to attribute to a counterweight, but I listened to some 20 LP's that I know VERY well (classical, jazz, vocals, etc.) and it is NOT my imagination. To verify what I was hearing, I put the original Rega counterweight back, did some more listening, and the improvements I had noted with the "Heavy Weight" disappeared.

In addition to the improvements I heard almost immediately, I also noted on further listening that the high frequencies seemed more extended and natural -- particularly cymbals, triangles, and bells, as well as the upper frequencies of violins and brass instruments.

If you own one of the tonearms mentioned, I strongly urge you to buy the Express Machining "Heavy Weight". I feel like I've made a wonderful discovery, and would have been very pleased with this performance at twice the price. It's almost like stepping up a notch in the quality of your cartridge.

The "Heavy Weight" is sold by several retailers. I got mine from "The Elusive Disk", and I think that The Audio Advisor also sells it. Now, stop reading this post, and get online and order one for yourself. I firmly believe that you are going to be very pleasantly surprised.

Thanks SD I was contemplating starting a thread re: this topic to see if any one had feedback. I have the 600 arm and am considering taking the plunge . Again, thanks. Mike
I believe that on the OL modified Regas the arm's tailpiece is replaced. My OL RB250 came with a circular weight (not off-center) that is tightened by a set screw. Has anyone replaced this version with the Heavyweight, and if so, how dramatic were the improvements?
I have a OL RB250 arm and the rear stub has a larger diameter than the stock Rega arm.I tried the Heavyweight and will not fit. I wish it had, it might quite a improvement on my Rega Planar 3.
Some folks at audioasylum have delved deeply in to discussions about the Heavyweight and/versus OL mods. A trusted fellow 'phile of mine had a similar experience to Sdcampbell when he got the Heavyweight for his nephew's Rega 25. He thought it was a huge upgrade. I opted for the OL-250, but have not been able to listen to it because my NA Interspace has had some problems being built and shipped to me. It has been 3 months, I am soo pissed. Sd, I am glad you are happy with your new weight:)
Hi, guys. I spent another 4 hours this morning listening to some favorite LP's, and I continue to be pleasantly amazed at the improvements from this counterweight. Frankly, this purchase was a real experiment, and I thought I might -- at best -- hear some very minor improvements. I was not prepared for my Rega RB900 to sound like it had undergone a major upgrade.

The comments above are correct that the OriginLive mod includes a different counterweight that has a set screw. The "Heavyweight" counterweight, however, costs a lot less.

I should have noted in my post that the "Heavyweight" for the VPI tonearm costs a bit more -- $100, rather than $80. And I was apparently incorrect that AudioAdvisor sells the "Heavyweight". It can be bought from either Elusive Disc or MusicDirect, both of which sell the version for Rega tonearms for $80.

Damn, I love finding an inexpensive tweak that yields this kind of improvement! For more info, here's the Web address pertaining to the HeavyWeight: http://www.expressimoaudio.com/weight/index.html
