Donuk's system

Post by donuk » 2019-05-06 19:13

I used to have vinyl - LP12, Uphorik, Dynavector, &c
Got rid of it all a few years ago - suddenly the cottage got a lot bigger.
Now have Melco, Linn ADS/Kat, and the speakers are Totem Model 1 Signatures.
I have had two amplifiers out on the racks (Isoblue) for some time. The problem is that I have been undecided between my Tundra 2 and my Linn Klimax. In my view they both do some things better. To such an extent that I tend to change them over every week.

After some contemplation I have now decided to use both simultaneously - bi-amping my speakers.

Both are connected from an output from the streamer by Linn silvers, and I use split K400 cables to both.

It has been necessary to spend a little time calculating and experimenting to fit a simple attenuating voltage divider network at the input of the Linn Klimax to approximate the gains.

And the result? Lovely. Speakers disappear even more behind a confident tuneful presentation. I have used the Linn to drive the main drivers and the Lejonklou to drive the tweeters. I may experiment further, but I am still at the stage of playing through old favourite tracks and hearing just a little bit more of the music.

interesting that it works for you - but x-check after a while.
I am saying this because it not really worked whenever I had the chance to hear bi amping with two different amps.
It might sound more impressive (hifi) in the beginning but also somehow disconnected.
However Linn/Lejonklou pairing might be an exception.
Please keep us updated.

OK Defender, I have to admit, you have a point.....

So I have lived with bi-amping for a few days. Some things are better.
There is an even wider sound stage, and more detail in the music comes through. It is possible to hear hidden instruments a bit better on many tracks.

I have tried swapping the amplifiers around. Perhaps surprisingly, I prefer having the Linn Klimax Twin driving the tweeters with the Lejonklou Tundra doing the rest of the work. I would have thought, given the power difference, that it would work the other way round. But no, apart from anything else, there seems to be a tiny bit more bass with the Tundra doing the work. (Although this could be caused by the inevitable inaccuracy of my homemade attenuator placed at the Klimax input to give both amplifiers equal gain.)

The bi-amping sound seems to produce an enhancement in the middle frequencies; a bit like having the presence control enhanced on an old fashioned amplifier. This effect I suppose could be the result of the cross over frequencies not quite dovetailing properly.

Anyway I have put the links back in the speakers and powered up just one amplifier. More musical, more rounded, more focussed but a narrower presentation. More green this way too......

My problems are not over though. I still have to decide which amplifier best suits my system and my ears - the Tundra or the Klimax. I suppose I will just have to give them one week on and one week off again so neither of them gets upset.

I am forming the view that many hifi upgrades are simply the process of substituting one set of strengths and weaknesses for another. When you get a new component in a system you immediately hear what it does better; then the faults grow on you and you want to try something else, which for a while sounds better...... All good for the dealers.

mmh now I am unhappy - I really hoped you would be the exception ;)
I know what you are saying because I am through that many times too. Actually I probably have sold more musical devices for some more impressive ones.
Thats why I am so happy the closing of the Linn forum was making me go to that forum. Here is soo much really good and usefull experience available.

In your case I would recommend to try your 3 possible setups (with Klimax only with Tunra only and both bi-ambed for a longer time).

Tundra and Solo options :)

By "Tundra 2", do you mean version 2.0, or is your Tundra Stereo at Tarandus level, at least, if not the latest v2.5? Otherwise, can you borrow a later/latest spec Tundra 2 to see if you think it's worth upgrading your Tundra 2(.0?) assuming an updated Tundra helps you settle on one .. or the other?

Don's tundra isn't tarrandus and I have offered to lend him mine. Mine is a 2.2
A 2.5 would be a very interesting test however and I personally would just stick with one amp. I still prefer the stereo too.
ADS3/SagMono/Tundra 2.2- . Totem Tribe Tower.
Lejonklou demos available in the N of England.
