VPI Fatboys versus others in its' tonearm weight class.


In their never ending quest to push fiscally responsible audiophiles into bankruptcy, site members have succeeded in making me consider a new gimbaled tonearm to keep a Lyra Kleos company on a VPI Classic 2 turntable. Dover, on my previous thread, pointed out most other tonearm options would be limited on the Classic 2 short of major surgery to it. So here I am considering keeping the tonearm upgrade in the VPI family. Their gimbaled Fatboy, will readily fit onto the VPI Classic 2’s tonearm base without any fuss.

Here’s my question after reading up on the Fatboy. How does the Fatboy compare with other tonearms in it’s $4500 price range? Is it about average in that class, which would be acceptable, or is it much better or worse than its’ peers?. If you.ve had any chance to compare the Fatboy with other tonearms in the same price range, what is your impression? I don’t want to spend that much money on one if the consensus is that it’s at the bottom of its class, which hopefully it isn’t.

I haven’t had an opportunity to listen to one, or any other tonearm as expensive. I would likely need to arrange a two day road trip to accomplish that. In lieu, I’m soliciting your impressions as to whether the Fatboy is worth that much compared to others in it’s price range. I guessing it will be okay, but don’t want to spend $4500 if the consensus is it’s at the bottom of its’ class just because it fits easily on my turntable. So what do you think? I’m all ears.

I’m not looking here for alternative solutions to a Fatboy. That was the topic of my recent thread, I’m only soliciting your impressions of the Fatboy compared to other similarly priced tonearms, and why I should or shouldn’t take a chance on it. Thanks all,

Mike

From skyscraper’s photos and Dover’s post, it does seem that the tonearm is "surface-mounted" on the plinth. Apparently there is a wide diameter hole that can’t be seen in photos, which permits the vertical shaft of the VPI tonearm to penetrate the surface of the plinth. This arrangement does not at all preclude the possibility that another true surface-mounted tonearm, like a Triplanar or any Reed tonearm could be mounted, if skyscraper is willing to drill three very small screw holes needed to fasten any of the named tonearms in place. The TP, the Reeds (and the Dynavector DV505) reside entirely on the top side of the deck; they have no vertical shaft that needs to penetrate its surface. In my book, drilling the small screw holes for fasteners does not damage or de-value the turntable any more than its age, place in the VPI pecking order (it’s not the latest version of the Classic, after all), and general desirability. Anyway, I apologize for being one of the protagonists for changing the brand of the tonearm. As to the Fatboy, there seems to be general consensus that it is superior to the original. Plus, the mating between tonearm and cartridge (not tonearm and turntable) is the major determinant of "success", which really boils down to a matter of opinion. So, given skyscraper’s reluctance to do any mods, why not buy the Fatboy and then take care to mate it to a cartridge that complements the characteristics of a Fatboy, and then listen. This is how one grows as an audiophile, not by asking advice from we who are strangers.

Lewm. The VPI Classic 2’s tonearm is composed of a number of interconnected platforms, arranged somewhat in the manner of how you might picture a split level house.is constructed. All the various platforms sit on a fair sized round disk attached to the plinth.

Its not readily apparent how the lowest disk is attached to the plinth, or how easily it could be removed to retrofit another tonearm. Could be it’s sitting in a big round hole, or screwed in from underneath, or some other arrangement. It would take some exploratory surgery to figure this out to see if another tonearm mechanism could be attached to the plinth. Might turn out to be something simple, might not.

It might be possible drill. three holes in the uppermost platform where the JMW 10.5i arm sits on it’s pivot to place another tonearm mechanism, but this is unlikely as the new tonearm would probably sit way too high.

If the Fatboy sounds a bit worse than any of the tonearms you mentioned, I’ll live with it, rather than take a chance on mutilating the Classic 2 turntable or otherwise making a mess. I’m either being realistic about my DIY skills, or simply. too lily livered. Appreciate your thoughtful suggestion anyway.

If you find a good match to a cartridge, it will sound fine.  Maybe some other VPI fans here can suggest a good choice. For me, unless the tonearm is grossly bad in terms of design and build, the important thing is that match to a cartridge.

Lewm, the more I look into it, the more the VPI Fatboy seems to be the logical choice. I’ve emailed VPI a week ago to see if they feel the Fatboy is compatible with the Lyra Kleos cartridge I have on order, but haven’t heard back yet. I think I read a Lyra cartridge was used to demo the Fatboy at an audio show when first introduced. But I would like to get that match confirmed by them with the current iteration of the gimbaled Fatboy. 

They offer the Fatboy in three different lengths, 9’, !0" and 12".. It would be nice if they answered to be able to figure out which to choose.

I’ve had my share of VPI tables and have upgraded arms within the brand BUT never got to a fat boy—only to a hot rod version of the 3D gimble. That said, in my experience the two most significant changes you can make sonically is going 3D from aluminum and going gimbal from unipivot. IME the 3D arm provides a much smoother and more natural sound than the aluminum tube. This is very easy to hear and welcome. The gimbal arm is easier to handle but does not extract as much detail from the grooves, leaving some realism on the table. If it were me and I had the table in the pictures you provided I’d slap the Kleos on the existing arm and see what happens before changing the arm. Part of the fun is in the learning so see what a nice cart does compared to your Ortofon Quintet Red which is vastly inferior to the Lyra.
