Hi, I've got this itch which I'm trying to scratch... At the moment I've got: source: Arcam DV88 proc/pre: TAG AV32R bp192 power: Arcam A85 + P85/3 speakers: B&W DM603S2, CC6S2; Mission 78ds. sub: REL Q150E Things which I would like to change: (1) I'd like an identical (or at least a much better match) centre speaker to my FL/FR speakers. (Happy to change all three!) (2) More accurate and deeper (but not louder!) bass. [Sometime later - not too important now: (3) I'd like to go EX/ES, but the only speakers that I 've seen which will go in the centre rear position are AG NM's and other egg on stalk models (e.g. KEF, Klegg neither of which would be an upgrade).] Things which I don't want to change: (1) Nice full deep sound, esp. in stereo that I get from the B&W floor standers at the moment. I've been really attracted to reviews (here and elsewhere - except WHFS&V) of the AGNMs and also Velodyne subs. I see my options as follows: (1) Replace all speakers with AGNMs. Keep REL. Cheapest option. Do AGNM's really need a better sub though? (2) Replace all speakers with AGNMs. Replace REL with AG MPS150 sub. Will I be happy with the depth of the MPS150? (3) Replace all speakers with AGNMs. Replace REL with (something like) Velodyne CHT-15. Will the velodyne be happy melding up to the 100Hz or 120Hz start of the AGNMs? My questions are: (i) Are the AGNM's (which are only more expensive than my current speakers if you include the AG sub) going to be a step up from my current set up? If not what should I look at? Dues? B&W Nautilus 8xx... (ii) Will I cope without a full range stereo pair at front? (I admit, I'm a bit of a sub/sat - o - phobe!) (iii) Am I being too miserly for partners for my prize component: the TAG? (iv) (Carefully lays bait...) If I went for AGNMs and a Velodyne where would it be best to get them from? Budget is not a huge issue. If I get value from £750 now then that's great. If I need to spend £3000 to make any great improvements then that's fine too it just won't happen for a year or so... Thanks for your patience, Charles.
