Congratulation! Enjoy. :-)

Thanks Beck!

Started at 8am and still playing records....

Apparently the bearing benefits from about 200 hours running in, so might as well spin some disks while I'm at it.

Already sounding very sweet

I followed Peter Swain's recommendation to replace the foam gaskets in my Espeks with a sealant. I wish I had recorded before and after clips as the difference is substantial, with improvements across the whole frequency range. It's like I have new speakers.

I applied the same torques to the drivers as I found when tuning torques by ear (1.2nm+1 for mids and base, 0.4nm+0 for tweeters).

would you care to elaborate on the details of the sealant you used. might be a good experiment for my spare kabers.

I followed the steps detailed here and used the same sealant recommended: https://hifikabin.me.uk/viewtopic.php?t=2665

I was initially planning to test with a pair of sacrificial speakers. I'd previously experimented with replacement gaskets and proved it was possible to degrade the Espeks' musicality. I was cautious because sealing is not an easily reversible step.

However I was persuaded to try, and after testing on one tweeter, decided it was clearly beneficial and sealed them all.

[springwood64]

I've moved the turntable onto a Mana wall shelf, mainly because of footfall issues.

It also means that Källa is now on the top shelf.

I have installed several of these wall shelves and every owner has been extremely satisfied. Some have supported the record player with additional Soundbase 2s. In any case, this is the best wall shelf I have ever heard. Above all, it looks very good and I hope it sounds good too.

[springwood64]

Yes Hermann it sounds great and completely solves the footfall problem. I can bounce up and down on the floor immediately in front of it and the deck doesn't skip.

I've measured the vibration on the glass mana shelf Vs the quadraspire shelf and the mana shows about 1/5 the peak amplitude of the quadraspire. The LP12 plinth records a much lower amplitude again, which I guess is the impact of the trampolin base.

[Hermann]

That is of course one of the functions of the wall shelf. But it can often do much more. Over the years I have tried to combine the trampolin (II) with Mana several times, but each time without success. In my opinion, a missing base plate and small 3M rubber feet on the corners of the LP12 are the most musical method of operating the LP12 on Mana.

[springwood64]

Interesting. Well that's something I can test on my setup. Do you have more details on the feet you've used?

[Hermann]

Here are two pictures that show this. Distrelec offers these feet for a small amount. But maybe you can find another supplier.

Maybe some thoughts on the Boazu that you have in mind. For many years I was fixated on Naim, because basically only this brand offered the sound that I liked. Since then I have only been very peripherally interested in other manufacturers. Back in 1982 at the first High End in Düsseldorf I knew that very, very few systems met my requirements. This has been confirmed in recent years when I visited hi-fi trade fairs again after decades. The last one is just a few months ago and I was really amazed that a Linn Majik DS with Boazu and Keilidh can outdo every single system at the hi-fi trade fair.

The quality of the musical representation of the integrated amplifier Boazu is very reminiscent of Sagatun/Tundra. But as often when it comes to the very last bit of music, the price for the last 5-10% is usually significantly higher.

[springwood64]

Yes, I agree. Boazu is fabulous, so enjoyable. I'm concentrating on improving my LP12 for now.

Every time I play a disc I relish how enjoyable it is. Källa has been taking a bit of a back seat in recent months.

In my opinion, a missing base plate and small 3M rubber feet on the corners of the LP12 are the most musical method of operating the LP12 on Mana.

This reminded me that me and a couple of friends tried various combinations of baseboard, Trampolinn and rubber feet back in the day and came to the same conclusion. Reporting the findings got me letter of the month in the March 1993 issue of Hi-Fi World!

[springwood64]

I've recorded a 'before' track with the Trampolin in place and have received the 3M bumpons.

Now I just need to figure out how to remove the tramp.

Obviously I don't have a jig, so does anyone have an idiots guide to removing a tramp 2?

Is it just a case of removing the 10 Phillips screws on the base and lifting up the deck? Or is the tramp also attached with an earth inside the plinth?

[springwood64]

Btw, I'm listening to supertramp right now and it sounds wonderful, even better than it did on the Quadraspire. If removing the tramp makes it sound even more musical, I'll be pretty surprised.

[springwood64]

... so does anyone have an idiots guide to removing a tramp 2?

It turned out to be simple, even with the earth strap. I just removed the screws as it stood on the shelf

Interesting, the issues are in their archive. You can find them here if you're interested.

https://www.worldradiohistory.com/Hi-Fi-World-UK.htm

If I remember correctly, it was in the early 2000s when I got the information. First I tried it without a base plate and with small pieces of wood of the same thickness in the corners, and a little later the idea of ​​using 3M rubber feet. A huge leap.

A jig to remove the tramp would be an advantage. Even if a wire is connected, it shouldn't be a problem to remove it. Thomas can certainly help.

I'm glad you like the music so much. I also remember that I put a strip of foam rubber between the wall and the frame. It sounded a little better there, but the wall was a little rough.

[springwood64]

The frame is bolted on to 18mm hardwood structural ply backing board with M6 T-nuts, and 3mm rubber washers between the ply and the frame.

The ply backing board is bolted to 3 stud uprights with 6 lag bolts.

Many years ago, in a different house, I had a wall shelf screwed into the bricks of an external wall, and the shelf collapsed one night, flipping the turntable over and landing on it. I came down the following morning to find it leaking oil on the floorboards. I wasn't going to let history repeat...

I enjoyed reading your letter from march 93, thanks to Hermann's link. Great bit of empirical testing.

[macrotech2]

Thanks Pete.
I’ve just reread it myself, comes across as a bit arrogant in places but there’s “youth” for you! :-)

[Hermann]

Hello Macrotech2

I had forgotten to congratulate you on the article, but I'm happy to do so now. At the time, these types of tests were definitely different from the Meinstream. It was the time of Linn/Naim's single speaker demonstration. Reminds me of visiting some shops in London, near Tottenham Court Road. I was staying in the Grafton Hotel. That's where I heard the Isobarik for the first time. A very moving time.

@Pete
The construction seems to be very stable. The shelf benefits enormously from this. And there is no risk of it being warped.

It seems to me that the nut is attached underneath the spike. If that is the case, I would first screw the nut on from above. It makes a very small difference, but it is reinforced by the pointed spikes. And if these are made of stainless steel, it is better. Since you are currently enjoying the sound, I suggest doing this before the bigger action, if that is an option.

Enjoy

[macrotech2]

I was lucky at the time of the article to have visited John Watson, Mr Mana himself, to hear his amazing system and see how it evolved, along with his Mana supports.
It was he who suggested trying the 3M feet and supplied me a set!

[Hermann]

We're stealing a bit of Pete's thread. Hope it's accepted.

It's quite possible that the information came from his forum at the time. During my visits to him in Wales I had the opportunity to take a closer look at the Ninja LP12. Unfortunately the Sumiko he used was no longer available. But I was more than happy with my Troika, especially when Expert Stylus carried out several retippings. The 52 he used was also modified, if I remember correctly by the later designer of the ECS amplifiers, initially sold as the Mana Stealth.

I was actually fascinated by the system, but also by another one, from a forum user near London at the time. That was the second system in this compilation.

By the way. Contact with this music lover and his family has been re-established for some time now through another user from the time. Music somehow brings people together in a beautiful way.
