When they were new, the 2050i were about £500/pr, take that into consideration.
You might find bargains on the 3050, as the 3050i are now out.
Q Acoustic 3050 - £299/pair -
Q Acoustics 3050 (Matte Graphite)
Cambridge Audio SX80 - £250/pr -
Cambridge Audio SX80 (Walnut)
Wharfedale Daimond 230 - £200/pr -
Wharfedale DIAMOND 230 (Black)
These are all good speaker. I've not heard the Cambridge SX80, but I have heard some bookshelf, and for the money they are fine. But I think you will probably get more fine detail out of the other speakers.
And for reference, these are the latest 3050i -
Q Acoustic 3050i - £650/pr -
Q Acoustics 3050I (Walnut)
I had the 3050 in my home for a few months and was very impressed with them. The rated bass isn't that deep, but the perceived bass is fine. Like all floorstanding speakers, they need some space around them. But they are workable in most situation.
Probably best if you listen with Headphones, but here is my review of the 3050 -
For £250/pr or £300/pr, these are very good speakers, when you consider they original cost near £500/pr.
Very clear, nice detail without being sharp or overbearing, smooth without being dull, I was impressed.
The Wharfedale are a very smooth speaker which I find nice for music listening, but my older models might be a tiny bit recessed for Movie Dialog.
I commented on the Q Acoustic 3050, which I have experience with, and mentioned the bass, the bass is high enough that you could add most Subwoofers if you feel the need, and fill out they very low end. You would simply have to cross the Subwoofer at the natural low end roll off of the 3050.
As I mentioned, the 3050 do have impressive sounding bass, but it really does not go that deep.
