I have finally set up the reverberation injection. My DSP3000 turned out to have some problem (vanishingly low output), I hunted DSP100 and got a pair of Focal Twin Shape speakers as the RI (2x5" woffers + 2x 6" passive radiators + inverted dome metal tweeter). Finally, I managed a quick n dirty set up today (4 channels) and listened. This is incredible! My small, dead uninspiring acoustics turned into a lively listening space. Walcha's Bach Organworks LP's sounded like never before and I'm quite familiar with gothic churches and pipe organs. A quick run through chamber, orchestra, vocals showed a new dimension and playing with the presets is just pure fun. Like several who tried testified - there is no way back to the flat, boring stereo listening. Also the initial listening shows what Romy suspected - bass capable RI helps to ameliorate the bass deficiency of the Dannoys. I'd like to make a proper setup. Any tips? I plan to mount the Focals (this is the best I could get for  a reasonable money) at the ceiling, angled down at the listening position like the Yamaha manual says. The RI tweeters will be some 230cm off the floor, while the main Dannoys are 95cm. Now they are much lower resting on books, chairs etc. I hope this is not too high and the Focals will manage. How do you set the volume of the RI? Matching to the main channel volume via pink noise. So far I've set by ear. Cheers, Jarek
