Yping - At this point in time my system is performing at a very high level thanks in large part to all of the cables I have.
For the time being I'm quite happy to enjoy my new found "nirvana" - until I walk into my favourite hi-fi store and get blown away by considerably better sound.
Depending on what kind of music you like, other worthy contenders in the speaker department are the Tannoy models Stirling, Turnberry and Kesington. For something more modern looking - take a look at the Definition range
They don't suit everyone's ears, but for many - they are the last speaker they buy.
I actually prefer the Tannoy's mentioned above much more than the Gap 828, they are better suited to my musical tastes. They convey voice significantly better than most other brands for some reason, and they can handle large orchestral pieces at significantly higher volumes than most, without being fatiguing. They are not perfect by any means - they tend to have a smaller sweet spot for one thing and you have to toe them in significantly more (so I'm told) than most other speakers to get the image depth. But once you have the correct alignment they sound so sweet.
One thing about the Sonograms - they may be Gershman's "entry level", but they should be viewed as a high performing speaker for the smaller listening room, like mine. The differences between them and the Gap 828 are, to my ears, quite small when considering the volumes I tend to listen at. The 828's may be significantly better with a more powerful amp in a larger room and different musical tastes.
So, I don't believe I will not be upgrading any time soon and when I do it will probably be to one of the Tannoy's
