Well, you've not answered my post 51 above. I thought I'd return to this three-month-old thread because of my new purchase. You seem to think that people who get their sets professionally calibrated are wasted their money and could do it themselves. Very briefly, I can show that I wouldn't waste my money on something that wasn't real.
About six years ago I had the Tannoy TS12 subwoofer, see review here
http://www.whathifi.com/tannoy/ts-12/review. At that time I had more money than I do now and I read reviews of the Paradim Seismic 110 subwoofer, for example this What Hi-Fi one
http://www.whathifi.com/paradigm/seismic-110/review and this Home Cinema Choice one, now reproduced on Techradar here
http://www.techradar.com/reviews/audio-visual/hi-fi-and-audio/hi-fi-and-av-speakers/paradigm-seismic-110-901098/review. So I thought that the Paradigm would be better than my Tannoy, and so it should have been, at thrice the price! So I went to my local dealer, the Home Cinema Centre then only seven minutes walk from my flat. For comparison, I took my own Tannoy subwoofer with me, because it's important to have a known product when examining a new one. I had the money with me, and I was fully prepared to spend £1,200 on the Paradigm subwoofer. The dealer connected both the subwoofers, and we switched between the two on various Blu-rays and CDs. To my astonishment, I couldn't hear much of an improvement in going from the £400 Tannoy to the £1,200 Paradigm! And I was
expecting, and indeed
wanted, the Paradigm to be clearly better, and I was fully prepared to be paying £1,200 for the Paradigm that day! So, after about half an hour I left the shop, with my Tannoy subwoofer - and still with my £1,200!
