2 lk-85's or 1 lk-140

You gotta _hear_ Aktiv. Go to a Linn dealer and check it out. I had a dealer with a pre-rigged comparison display and it only took seconds (really) to hear the difference. Amazing and has challenged my pre-established upgrade path (still uncertain). My hunch will be you'll see the value in 2 LK-85's Aktive over either amp you're looking at passive.

Have fun.

Oh god!

Compare Kairn, 1 LX-100 passive + Kaber Speaker
vs
Kairn, 3 LX-100 Actif + Kaber

I have begin my live with Kaber Loudspeaker with 1 LX-100.
I have buy 2 more LX-100 + activ card.

My worst choice ever!!

Sound better .. Yes! but worth the price ... GOD NO!!

Keep your cash and buy a better amplifier.

Your activ system will be unsellable after. If you able to sell all your system , you very lucky! Who want pay 10000$ without have heard in their room the result?

Now I still have Kaber but I work my Kaber passive with 1 x LX-100. I have keep my 2 others LX-100 for my new MagnePlanars 1.6. The result not so fantastic because 2 x LX-100 still not have enough power to drive them correctly.

I don't know how are LX-140 vs LX-100 .. but 40 more watts seem to me to be a small upgrade in power.

Lugnut and Thsalmon are right: if you have a retailer available, passive vs aktiv is not a major change for the Keilidhs, so I wouldn't worry too much there.

For the amps, if you're going to be getting LINN speakers anew, get aktiv 85s or 140s without question. The new crossovers on LINNs make passive vs aktiv a snap to do in minutes.

Having just bought a new system (all Linn), I looked at a few options and ended up with

Ikemi
Wakonda
2250
Ninka

I listened to the 85, 140 and 2250 and the 2250 is clearly a much better amplifier than any of the others. My next intention is to get another 2250 and go active !

Quite simply, a better amplifier is a better amplifier - passive OR active !

absolutley - if you have the money, a 2250 is the best way to start
