New Amp to go with Arcam DIVA CD-72?

[Raider]

I've had my current hi-fi setup for quite a while now, and unfortunately i haven't been able to use it recently.

Now i'm moving into a new place where i'll be able to set it up in my room along with my TV / Xbox 360 etc..
I'm currently running:

Arcam Alpha 1 amp
Arcam DIVA CD-72
Acoustic Energy AE-109 Floorstanders

I'm looking to upgrade my amp, with around £400 to spend. I would normally do my usual thing of going to my local hi-fi place (which is excellent) and have a good listen to some of the kit. But i've been wondering about maybe buying second-hand instead, to get more bang for my buck.

I like the idea of getting an Arcam DIVA amp to match my CD-player, maybe the older DIVA A85 (now replaced by the A90) or A75 Plus?

I listen to a huge range of music, so the amp has to be a good all rounder, and from my experience i've always been more than happy with Arcam kit. So any opinions? Ta

I'd feel really guilty listening to stuff then buying elsewhere though

Maybe they'll have something 2nd hand or new that I could buy though

I just have the feeling that my speakers could use some extra power to get the most out of them. Is 30W / channel really enough for floorstanders?

For reference when I bought the AE 109s (or ME109s as I keep calling them), around 5 years ago, they were very similar to B&W 602s, but in floorstander form.

What makes you think the CD-72 is the weak part of the system?
