In theory - for maximum information retrieval - the bearing and arm must be as firmly coupled as possible. In practice though the coupling medium will always have some resonant behaviour at audio frequencies. Simply put, resonance works against accurate information retrieval. So, some compliance in the coupling medium is not necessarily a bad thing.
Rega have gone down the road of maximum information retrieval, but in doing so had to create as non resonant a coupling as possible. Hence the use of unusual materials and stripped back design. Linn managed it with the Keel, but it required a very stiff but lossy (and expensive) chunk of heavily machined metal to meet both requirements equally.
The modified Technics uses a very different approach, where a massive ply sub structure can give a fairly stiff coupling, while not being inherently resonant. Anything massy will store energy though, which can cause some smearing in the signal.
As with many things, it seemed like a good idea at the time, but I’ve recently be considering a ‘tweak’ to make it all as one. The mind boggles as to the impact it will have, but sure it’ll be a bit of fun finding out!
Thank you.
The cable has a din connector on the base of the arm and then goes straight to the phonostage, no connectors as such (assuming you mean RCA/XLR)
Just because I’m not well versed in the ways of the LP12, how does the Keel achieve both? Sureply a massive block of machined metal can’t be lossy? Or is in the machining?
I think the Solstice does something similar, from the pic on the link below, prompted by this discussion I just asked in the Solstice thread what the benefits are, if indeed that’s the way the Solstice is designed
Actually, thinking about it, a suspended deck has to have them coupled, which explains Linn’s approach, but I don’t think the same applies to the non suspended Rega?
Blockquote Sound signature of the amatis is more rounded, less punchy. More detail at lower volume listening
Thanks. That’s interesting, if there is one thing I would ask for in a different speaker it would be for a more linear sound at low volumes. It does seem like I need to turn up the B&W’s to sound their best.
BTW, I have paid to replace a diamond tweeter too , due to an accident throwing a dog toy.
I’m a very happy Contour s3.4 owner and a few years ago used them with a 282/300 too I now use a Supernait 2. If you ever get the chance try the Gaia II footers with them I found them very useful.
This is almost identical to my front room because of space and domestic harmony my system is in the right alcove with shelving above and the left is for records I use the ikea Kallax cubes stacked up 18 at present 16 of which are filled with 12" records
one other is for 7" and some box sets on average I get 50 per cube.
My speakers stand in front of the alcoves with one to left of the system so far from ideal but it works for me, the records, carpet, furniture all help with the room acoustics and to negate a bit f bass boom caused by the suspended floor I added some Gaia II footers.
Yeah L100 Classic. NAP 100 is doing surprisingly good, I have no idea why everybody says that it’s weak. I replaced it with my friend’s Accuphase E-380 and actually couldn’t hear any significant difference. But I can’t hear cables, so it’s just my opinion, but when I replaced Neats SX1 with these L100s - it’s a big difference, definitely a step up.
Thanks Bob,
Fortunately, I’m able to site the system along the left wall and use both the alcoves for Vinyl storage
My floor is Blue Lias limestone flags laid on sand and earth, so a different set of sound taming issues for me I guess. I’m laying a breathable carpet/rug to cover all but the outside edges which should help but we’ll see.
The room is not far off square too, so that may be another issue to try to cope with.
Here’s the floor freshly cleaned and sealed yesterday.
Yes, the shape and pattern of the machined pockets will have been chosen to minimise resonant behaviour while maintaining as much overall rigidity as possible. Obviously weight reduction and distribution are also important to how well the suspension works.
