Which very dynamic speakers would you recommend?

I second Pbb's motion enthusiastically. Paradigm is a brand that some audiophiles love to hate because (1) they sell a lot of speakers and (2) they are a Big Corporation.

The reference series offers incredible value for money. The TOL Studio 100 has gone head to head many times with speakers selling for 2-5 times as much and has held its own admirably. I use them for HT but, you know, if I had to sell my 2-channel speakers life as I know it would not end.

Just a couple of things to keep in mind. First, they love power. Second, they aren't the best choice of quiet background music. They like to sing!

Pbb is dead on -- try it in your own environment if at all possible. I like the 100 v2 as well. If you like something with more presence, try one of the Thiels (the 2.3 is very nice). If you like something super smooth throughout, check out the Montana line-up. Good luck.
By the way, if you can't find the self-adhesive felt, you can buy tweeter surrounds for $10 or so here on Audiogon -- look for the billboard.

The Paradigms are an excellent choice. For the types of music you like you might want to give the less expensive Alons an audition as well; very open sounding and dynamic.

Goodgirl,I live in UK now and I would recommend you Paradigm as well..It depends on how much you want to pay..I also use Paradigm Studio 100..they are quite good..In fact they are unbeatable up to 5000 $ speaker range..bass is tight and deep..and Paradigm is very musical.I respect this company a lot for producing good and affordable speakers..
but if you can spend 5000 or 6000 USA$ then you should go for VMPS RM40 or Legacy Audio Focus ..Below 5000 $ don't buy anything else than Paradigm ..

Based on your existing equiptment, try Kef Cresta 2 or 3s. They are cheap and clear sounding with good tonal balance. If you are planning to upgrade your electronics, buy the best speaker you can afford. I do not find the Paradigms dynamic at all. They are dull, distant, with very little low level resolution and definitely lacking in "prescence."
