Did you guys ever know of the RedWine Audio Signature 30.2, USD2500. It got one superb review from 6moons audio, stating it blows USD45k amps out the roof.

Main point..the Sig 30.2 is a T-AMP, one small T-AMP board, almost similar to the one we are getting at rm50 a piece. Another GainCard 47 cerita biggrin.gif

jazzy, i just asked chchyong to get me some full range drivers.

I suppose this is where I end up messing with speakers sad.gif



needs a spanking new amp. Cant decide which topology to use yet.

it's either a fully complementary Current Feedback (ala Pass F5, except three stage) or Folded Cascode biggrin.gif

Untunglah your gf.. hehe

I am thinking about moving out from amp building(too much already) to speakers building.
Was intrigue about open baffle a while back.. kinda hard to get good drivers here in bolehland.
Now that someone is offering the service and goods, maybe I'll take another look...
A speaker thread coming up..? tongue.gif

I need to have something like a speaker to start with! laugh.gif
I am thinking about building an open baffle.. small enough for a desktop use before jumping for bigger versions. problem is.. its kinda hard to get right drivers (with the right price) in bolehland... maybe I start to salvage some of the drivers I have around the house... Now that just gave me an idea.. I'll come up with something today! whistling.gif
