One hour in....
Spikes not adjusted to the nth degree yet but stable. Stand pillars not filled yet.
Speakers still 'cold' and positioning not optimal yet until I move stuff around a bit. (Want them just a couple of inches from wall eventually. Currently 18 inches from wall.)
Incredibly detailed, suprisingly so. Imaging better. (Toed in about 20 degrees)
Absolutely no 'boxiness' and none of the one note 'BS bass' my R3's evidently had a little bit of - deeper down - courtesy of those ports.
I think once I have filled the stands and got them much closer to the wall then any apparent gap in bass is going to be tiny. (The R3's did only have 5" woofers after all, so most of what I was hearing before was from the box and the hole and tuned to one frequency.)
They are fantastic with the jazz I have played so far (a couple of tracks from Sinatra at the sands and some Pearl Django and Bucky Pizzarelli) and I am now enjoying the recent BBC drama CD of John Le Carre's.. 'A Murder of Quality' which is amazing me with it's intimacy and detail - especially considering these boxes are still cold.
I did not like the shabby quality of the GRP damping on the underside of the stand plates and had to spend a good 30 minutes with vacuum cleaner brush attachment getting rid of of the loose bits of chopped glass fibre from them - and from the floor (and from the hall where I had chopped up the box for recycling.) Cheers Partington! Bitumen damping sheet would have been tidier and not shed bits of glass matting fibres everywhere.
