On Audiogon: Paradigm Studio 100 V.2 Black Laminate
No relation, but a great speaker for the $.

I second the rec for the Paradigm speakers. I think they are neck and neck with the PSB speakers, try the silver or bronze out. They are a bit dark, but very forgiving of the source electronics. They can be had for a steal even in their high gloss piano black finish.

I third the Paradigm Reference Studio 100.2s. I own them and just adore them. I auditioned in my house the Triangle Celius and was happy to get back to my Paradigms. You are right, the Triangles are simply weak in the bass. Also the Paradigms are SUPER easy to place. I have mine with the cones only 26 inches from the back wall and sound just as they did when they were 40 inches away. I have moved them all around the room with little change in sound. They are flat out amazing speakers in terms of sound quality and look great too. They do like power but I think 75W should be enough for all but head-banging levels - they are 90dB sensitive afterall. Good luck -Arthur

Soliloquy 5.3s will be happy with your 75 wpc amp. And you will here the buzz of the rosin on the strings without it being tinny bright.Response 35hz to 20 khz with a benign impedence curve and narrow phase response. This will also give you the option of tube gear on down the road.Make sure to pick a speaker that will give you options,so not to close the door on experimentation.That's the fun of being an audiophile!
