Help! Tweaking My Lovan Rack for new Big A**ed Transrotor Turntable!

Folks, some input would be mighty appreciated.

I’ve been using a hand-me-down (though very nice!) Micro Seiki dd-40 turntable for a number of years and finally got the upgrade itch (it helps the upgrade itch when your cartridge is going on 30 years old, and sounding like it!).

I went down the rabbit hole and picked up a Transrotor Fat Bob S turntable, with an Acoustic Solid 12" arm and a Benz Micro Ebony cartridge. All with only about 30 hours of use at a great price. Yay!

Though I have considered getting rid of my old Lovan Classic rack for a new custom jobby, I’m pretty much spent out and I think I’ll have to make do for now, working with the Lovan.

The Fat Bob turntable is 55 lbs of solid aluminum and built like Thor’s hammer.

I figure this will finally get me to fill my Lovan stands for a bit more rigidity - probably with rice. The stand is the old 3 legged triangular shaped bass, which means the thin MDF shelves can feel like they sit sort of precariously on top. But the stand itself feels quite solid.

I want to incorporate a wood platform base, as many do, because I really love the look of a nice wood slab.

At first I thought maybe I’d have 3 spikes drilled in to the bottom corners of the wood base to directly couple it to the rest of the Lovan frame, vs resting it on the top mdf shelf. But I’m not sure that’s really necessary. And I’d like to incorporate some isolation as well, I think. So I’m thinking of just laying it on the top shelf, with something in between.

My first thought is to place a Symposium Segue shelf between the top of the Lovan shelf and the wood base.

Other than that...I’m flummoxed as to all the other choices...roller blocks? Symposium Fat Padz? Vibrapods? Herbie’s Tendersoft footers? Voo-Doo Isopods?  What should I put between the wood platform base and my Lovan shelf?

Any comments of suggestions on the direction I’m going?

Thanks!

(BTW, I’m an resolutely NOT a DIY/Handy-man type, so I’m not trying to go to heroic efforts, wishing this to be as painless as possible).

OP; Welcome to the Transrotor club. Your Fat Bob S will give you years of listening pleasure. I have a Transrotor Apollon with 3 motors and the triangle design with spiked feet going into cones with rubber feet, I think somewhat similar to yours. I too looked for wood but since the system was heavy, over 100 pounds, and large, I opted for a dedicated stand from Clearaudio, the MontBlanc. It’s really a solid beast with a plexiglas as the base, and concrete filled CNC polished stainless steel foundation. It’s more of a modern design, rather than the homey warm classic feel of wood. I have a zebra wood platform for my preamp power supply😀

My floor is basement, bamboo floor, and no vibration issues. Even with multiple subs blasting. I am a firm believer in rigid isolation with minimal bouncy isolation things for the turntable. I also highly considered the Finite Element stands due to their nice wood craftsmanship. Good luck.

Audioquest4life,

Sorry, I missed your comment.

Thanks for the welcome! Wow, the Apollon! And I thought my Transrotor table was a beast! Must be real fun.

I just received my Townshend Seismic Pods which I plan to use under the wood platform I’m having built. I had downloaded a seismic vibration measurement app, placing my iphone on my Lovan rack and then on my taller home theater rack. I must say I found it a bit alarming how much vibration was transmitted up the Lovan rack when I walked or lightly stomped near the stand - it was decidedly less on the bigger stand beside it (but that’s full of my AV gear and not suitable for my 2 channel stuff).

With that in mind, I’m looking for some more isolation. There are so many different opinions on this, ultimately I think I’m throwing together stuff that gives me my own piece of mind, without spending a million bucks. At this point I’m planning on securing the top Lovan rack shelf to it’s frame making it less tippy. Possibly filling the stand. I’m going to sit a Auralex Acoustics ISO-Tone Turntable Isolation Platform on top of the Lovan stand - it has lots of good testimonies for really fixing the type of sound transmission I spoke of. Then that will be the first base on which the Townsend pods will sit, holding the new 2 or 3 inch thick wood base for the Turntable.

I even picked up some of these isofeet:

I figured I might put them under the feet of my turntable (might help make it less slippery on the wood block, as well as help isolate), or alternatively maybe I’ll put them between the floor and the points of my Lovan stand.

My instinct says that stacking suspensions and/or squishy layers can have severe unintended consequences, especially the more stuff you layer in there. Keep it limited to 1 suspension or squishy layer, and it should be a good one. I had the "Gramma" version of those Auralex for speakers, and it’s not something I’d put a high-end 50 lbs table on...too squishy, and has a very cheap feeling (and sounding) MDF/felt top board.

Securing the Lovan modules (somehow) is a good idea; man that always made me nervous as heck when I had to curve around a back corner to do cable connections. And I know the slide-y glossy shelves issue all too well. Had a girlfriend once take a tumble, glance the rack (1 had 3 modules stacked with the CA Innovation on a maple block on the top), and nearly slide the TT off. No harm done in the end, though.

But your beautiful table really deserves a rigid-framed, 4-point rack! I’d look at something like the Adona AV45G in your shoes (not the modules, the full frame). ASAP. Not too crazy priced at $1K for a 3-tier (really quite sane actually). No affiliation, and I’ve not had one myself, but I’ve seen the Adonas in use on very high-end TT setups, including a pair of ears I’ve trusted for a long time. That should help immensely, and you can still experiment with high-tech/suspension feet under the table to address the foot-falls and feedback. I should’ve done that when I got the first Innovation, or stuck with a SOTA (man that spring suspension forgives a lot).

And I just remembered that Symposium makes a platform with a small suspension in the feet, for turntables, that users seem to love. But you’ll still want a solid stand under it.

@prof, 

What makes this hobby fun is the shared interests and experiences of others to help each other out. In terms of isolation, the more rigid and robust in terms of mass your base platform is, the better it will isolate the rest of the equipment from vibrations. My experience with that method is to spike the base platform to isolation footers to your floor, tile,  carpet, bamboo, concrete, wood, or whatever. This type of isolation works extremely well especially if the base platform sits on a rigid base...non floating floors, etc. Minimal vibration transfer will occur using this method. Then, the platform on which your components sit, you can experiment with a variety of absorbers, cones, or rubber feet,in the pursuit of vibration free happiness. I for one have relied on the spiked feet platform approach, and the turntable rests on a one inch thick plexiglass with semi-rigid rubber cushions. Works fine for me. The knock on the platform test does not reveal any vibration through the turntable. Of course, my platform mass consists of nearly 300 pounds of concrete poured stainless steel columns, ala, Clearaudio, with the aforementioned spikes. The mass of your Fat Bob will aid in helping to damp any vibrations as well. At the dentist nd of the day, spiked feet to the floor is one step in the pursuit of isolating vibrations. 

On another note, if you play music extremely loud, I have not found any way to isolate high pressure air disturbances on the tonearm due to extremely loud volume, which is probably not safe for hearing anyway, LOL. Unless, you move the turntable into another room. Once you pressurize a room to cause harmonic and resonant distortions, you are in another league, haha. I have not reached that point in my new room yet! 

@mulveling,

I fully agree with this statement “But your beautiful table really deserves a rigid-framed, 4-point rack”. 

Cheers,

mulveling,

Thanks for the input.  Believe me, I'd love to get a new rack.  Unfortunately the Adona racks are too big.  I'm working with a really restricted level of space, which is one reason the small size of the Lovan has worked well for many years.  If I get rid of the Lovan it will be for a custom design rack, but as I've said, financially that's a ways off.

audioquest4life,

Fortunately my turntable is in a different room, down the hall, from the speakers so air-transmitted vibrations won't be a problem.

When you suggest spiking the rack into footers, would you be thinking of something like these?
