LP12/Radikal Support

Post by Charlie1 »

Was recently reminded I wanted to try another Ikea Lack table with my deck. Last time I tried one, I cut the inards out of the table top as per 1980s advice, but subsequently read this makes the table springy and negatively interfers with the Trampolin.

So with new Lack delivered and left in it's normal state, I tried my LP12. I still found it inferior to my Isoblue rack where all my components reside. I also tried the new Lack with my Akurate Radikal. I found is had more negative effect supporting the Radikal than supporting the LP12. I'm quite surprised how much difference the Radikal support can make :?

So I figured that was it. Then a friend mentioned something he'd been told ref his TImeTables, that ideally both LP12 and Radikal/Lingo need to be on TimeTables otherwise you're always limited by the lesser support. Still not sure this really makes sense to me, but figured I'd give it a try even though the statement is aimed at a new table being better than the existing one, which the Lacks are not.

The result is that I felt the gap between LP12/Radikal on Isoblue and LP12/Radikal on Lacks was lessened. One time I thought the latter was actually better. Eventually got too tired to be sure of my tune dem results, but wondered what other members think and if they've ever tried something similar.

PS, I've got a pair of Ikea Corras tables to collect next week, so will try again using these as then both my LP12 and Radikal will be on identical supports.

PPS I also wonder if I need to be careful with this sort of comparison that the Radikal gets roughly the same amount of running time after power on. Each time it's moved between supports I have to switch off and unplug. Whilst I always wait for the light to dim slightly, I'm not measuring the time before needle hits the groove. The LP12 motor was well warmed up before any comparisons though - 1 hour probably. Radikal is always left on.

That's quite an interesting finding, Charlie. I haven't heard of this kind of synergy with the LP12 and Radikal support.

When I make comparisons between racks/supports/shelves, I normally turn the components around, so that the rear side is facing out. Then it's easy to just move them back and forth, without switching anything off.

I usually switch the LP12 off, but don't remove the outer platter, provided the move can be made nice and steady.

Thank Fredrik and good tip ref turning Radikal around - obvious now I think of it. Inspired me to have another go tonight ahead of Corras ariving mid-week.

This is most bizarre. To be honest, I was so tired at the end of last night, I thought today I must have been imagining things. But it appears not. First I rechecked the standard lack supporting Radikal but now no need to stop/start the LP12. Lack is out front of rack in both A and B tune dem, so maybe disadvantaged in being in front of the firing line of the speakers. This might be countered by it being slightly further away from the power amp. Anyway, it's awful compared to my Isoblue - a right mess (musically). Lack is plain rubbish. A very easy tune dem even for me.

So I then got the modified Lack out. Forgetting it's not ideal for a tramp LP12, I put the deck on that one (I don't remove platter either) It's to one side and still in front of speakers. LIstened again and now this sounds really good. I'm not tired and it's not an easy tune dem by any means.

Just had to write this now. I do need to be sure which of the two is best and also use the LP12 on the unmodified Lack, so back to work... update later. Weird or what :!:

Better on the Isoblue, but tough dem. Had to resort to Piano sonatos which are saved for tough ones :) Different presentations didn't help. Ikeas are less coloured and faster sound.

I swear the gap is much reduced when both units are on the Ikeas, but if anyone fancies double checking then that would be great. Surely it must be! It's so easy to tell them apart when just moving the Radikal. I guess they do sound more alike when only moving the Radikal though, so perhaps I can tune into the musical differences easier than when the LP12 is moved as well. AHHHH!

Incidentally, I think my LP12 (with tramp2) is better on the modified Lack after all despite the claim ref interference from springy top. But can't be bothered to double check that as well. --or maybe it's cos the Radikal prefers the standard Lack :mrgreen: I haven't the patience for all this (Don't know how engineers do this all day long. I guess it's different when you're the one developing a product)

I might actually listen to some music now :roll:

Tried a pair of Corras tables today, one under LP12 and another supporting Radikal. Isoblue was musically better using Tune Method - seemed an easy comparison tonight for some reason. Corras did similar things to the Lack so subjectively a more focused sound, but less engaging and able to capture the spirit of the music. Noted that the singer also sounded a bit bored and matter of fact with the Corras.

Might prefer Corras to Lack (unmodified) but didn't compare directly. Anyone ever compared the Lack to Corras out of interest?

Thanks Charlie!

No, never compared Corras to Lack. The construction is rather similar, but I noticed that the extra loose shelves you can install in the Corras don't sound as good as the bottom or top shelf.

I remember the bottom and top also sounded different, but right now I can't recall which was better of the two.

What type of floor do you have, Charlie?

It's an upstairs bedroom with suspended wooden floor, but you can walk around much of the room without causing the needle to jump.
