Years ago, I was at my usual dealer at the time, The Sound Gallery in High Wycombe, having taken in a turntable for servicing. While I was waiting for them to check something, they decided to entertain me with a demo of their new Laser Disc player with some Def Tech speakers they had just taken delivery of. I had never heard of them or seen them before.
They played a couple of scenes from Jurassic Park and a couple of songs from a Pink Floyd concert. To say I was impressed would be an understatement. To this day, I have never heard Jurassic Park have so much authority and weight. Same with the Pink Floyd concert. Really superb.
I was reluctantly getting my credit card ready when they said "hang on", check out some stereo music through them first as they knew that this was most important to me. My credit card was soon safely back in my pocket. The Def Tech speakers were almost unlistenable. Way too bright and overbearing and in your face. I guess the attributes that were so impressive for video were drawbacks for normal stereo.
I'm sure they have improved since then and might be worth a listen again.
