Best matching speaker for Alepha 3.

Unless you have a large room a speaker with at least 90db and 8 ohm should work fine.

I have used the Aleph 3 with both Meadowlark Kestrels and Dunlavy SCIVs both work fine, you can't however play VERY LOUD with either, but the awesome sound of the Aleph 3 makes up for the low power. If you are on a budget I believe that the Kestrels mate especially well, you can get a set used for around 600.00

I've been using mine with Mission 753's (91db 6 ohm), and it sounds amazing. My room isn't too small(maybe 12' x 20'), and I've never had a problem with too little volume.

I'm using an Aleph 3 with Quad ESL 63's in a room 19 x 14 x 9, and getting plenty of volume, good dynamics, and so on. I don't listen at head-banging volume levels, but high enough for realism. I'm using it with a Cinepro 10 Line Balancer, which may help. I'm using a passive preamp too, which works surprisingly well with the Aleph 3. Nelson Pass said he wasn' surprised, but expectations were against it.

Proac Response 1sc might be a good match along with the Merlin TSM-SE. Ahhh, another winner which I also heard is quite good for the Aleph 3 is the Dynaudion Contour 1.1's.
