PMC IB1 and room size

Sounds like a good combination. Try to get hold of a pair of 3b-st or a single 8b-st (4 channel) and use that to trimap the speakers - it makes a huge difference.

Hmmm, 225 square ft. is pretty small for the IB1's but since Jethro even had a single IB1 as the center speaker I had no further comments.

Jethro, out of curiosity what is the width of your room, and what are the measurements of your main speakers from the side walls? I believe the IB1's need at least 15' width of space to sound optimum.

The DAC-1 has really nice mids with the 4B-ST - electric guitar rocks in this setup IMHO. I've tried this exact setup but with the analog bypass of the SP-1.7 as a pre-amp. You may find less bass with the DAC-1 than other DACs such as Bryston's DACs and Bel Canto DAC3. This may work well since you have been using bass traps. I think you will be pleased.

I think the DAC-1 won't be around too much longer. I really hope to try the Lavry DA10 soon. The DAC-1 is a good DAC, with excellent features for my setup, but my experience with Lavry converters is that they come closer to sounding exactly like the source than anything else I've heard.

My room is about 13' x 18.5' - a little bigger than 225 ft^2.
My speakers are on the 18.5' side, 8' feet apart, shifted to the left side of the room. I luck out on the left side as there is a small opening which seems to take care of reflections. The right speaker is far from the right wall. I have a small sweet spot for music. I tend to listen with the lights off and my eyes closed because the speakers are pretty close. My center is the IB1-C and quite often I also listen to some music in PLII. I have heavy curtain behind the listening position. Everything is crystal clear and the bass is extended and tight. Although theoretically not a perfect setup, in practice it works well. I know of a very knowledgeable Bryston/PMC person who has used BB5's in the same setup with great success.
