what is the quietest air pump for my ET-2 ?

thanks Perrew but the link doesn´t work or is incomplete, may I ask you to repeat the link. many thanks

ok - got it now. Big machine but looks good. The question is are you able to run it the same room . I will ask Nortern Lights. Thanks Perrew

Oilmanmojo, yes this is a good recommendation. A friend of mine told me about the Troll from Junair and I ordered one yesterday. It should be very quiet. Nevertheless I do think I have to build a sound insulated case.

Ckniker, I use the Kuzma Airline too and also the Sil-Air Compressor. Nevertheless one has to run the Sil Air Compressor in another room (I do so too)because every 8 minutes you hear a sharp sound (zzsch) when the air echausts. People told me that the Jun-Air Troll/Minor 3-4 should be even better than the Sil Air.

I now received the Junair. This is a nearly noiseless compressor, you only hear air breathing... really! I do use in my listening room driving the Eminent Technology 2 and 2,5. You see a pic on my system site.

I also found two other solutions, one is an Ekon Air system which is a big compressor coming with a noise dampening box and the other one is a Japanese High-Blow fish tank pump also using the big dampening box and providing continous streaming flow.
