QUAD 2905 . humidity and reliability

How can anyone answer your reliability question? They haven't been around for 5 years.

The QUADS were designed in England! You don't get a much more humid enviroment than that! QUADs of all vintages are usually good for 20 years if not abused. My friend repairs them and has done both 63's and ESL57's.

Hi there

Which country are you in? Here Singapore, humidity runs at around 85%-90%. It is not kind to electrostatics. Martin Logans are especially susceptible, as the panels are exposed. Quads and Acoustats seem to be a little more resilient, due to the dust-covers I suppose.

Running Martin Logans here means you have to be prepared to change panels once a year. Even the sound changes depending on the humidity levels. They sound better when humidity is low, and become rolled off as humidity rises.

I love 'stats but I would never buy another pair unless I moved to another country with a dryer climate.

Another no-no for humid places is drivers with foam surrounds. They rot and crumble after 4-5 years. Even sneakers and sports shoes suffer the same fate!

Kind Regards

You need to use them in an air conditioned room.My last pair lasted 12 years before rebuild.I have heard Dynamic speakers in the over $50 grand price range and none of them have the accuracy and precision like the Quads.The only thing that can compare is,"live music".

Bkonig,
I agree with what you say about 'stats'. I used to own Acoustat 3's with the C mods. After a couple of years near the ocean in California, they were popping and having other issues. I sold them and went into dynamics and never looked back.
BTW, I also owned prior to the stats a pair of Maggie 1c's, which I actually preferred to the Acoustats. Nonetheless, neither have the palp factor of a good pair of dynamics, again IMHO.
