Guys and any Gals there maybe, I'm seriously considering upgrading to THX. At present I have a Denon 3801 and am looking to get a A1SR. Does anyone have one who can give me an opition as I can't find any reviews of it? I've heard one but only for about 3 minutes as I didn't think I was going to be able to afford one at the time. It sounded really good but has anyone heard one properly? Will it be as bigger leap forward from my 3801 as I think it will be? Does anyone know of anywhere in the Milton Keynes area I could get a demo? I'm also looking to upgrade my speakers to Kef TDMs, it would be great to hear from anyone with TDMs and a 1SR. Thanks in advance, Too Tall.
