How can I raise the height of the sound stage

Sit lower.

I agree with Fiddler. I have found that speaker cables have a significant impact on the shape and size of the stage. What are your speaker cables?

Try different cabling.

I recently auditioned CT cables and they dropped the soundstage a good foot. Went back to my silver cables and the soundstage came right back up.

You will need several stage hands.

Maybe you can tilt them back some, that should raise the soundstage

Or you could get lower chairs.

I built stands for my 988's by going to a timber frame housing company and getting roughly 5' of solid 12"x12" fir used for posts in timber home construction. The cost was around $200, and they cut it into two 26" lengths, one for each speaker. It definitely brings the soundstage off the ground, with only minor loss of some of the bass. I think it's worth it. I might go with 10"x10" though, as long as the spikes from the 988 would fit on it.

Let me know if you would like more information.

Hi Nke,

I have listened to the Quads, and loved the sound but found the soundstage to be exactly as you describe. I would recommend that you look for some stands for the Quads. Here is an example:

Check to see if your tweeters are working.

In addition to what Rhyno said make sure your phase is correct. Check to see if any of your pre/power/cdp inverts phase or not.

Regards,

get polarity correct.

(both signal and AC).

Perhaps some room treatment on your ceiling above your speakers.
