jaxwired: However, having owned both the spendor A6 and the MA RS6, I would recommend against getting the spendors. If you like how engaging and entertaining the RS6s are, I do not think the spendors will make you happy in the long term. I spent dozens of hours with the A6s and while they could be stunningly realistic with quiet acoustic pieces, they were not good "all-arounders". And you just can't get much further from the RS6 sound than the Spendors. For awhile, I had the RS6s and the A6s side by side and I could A/B switch back and forth with my remote control. Every non-audiophile I did this for preferred the RS6s. And it wasn't close. It was "holy cow. LOVE those black speakers" or "no brainer, dude", etc... I'm not trying to knock the spendors as I think they have great redeeming qualities and I can totally understand someone loving their sound. I'd just be surprised if an RS6 lover was happy with them, being so different.As I said - you can't do quick A/B dems with the Spendors as you have to settle into them - once you do, they're extremely musical. Quick A/B dems just make the Spendors sound dull, but once you're used to them, you realise that they're not actually dull at all, and do have the detail you thought they didn't have initially.
The Spendors may not be as good an all rounder as some, but you tend to find the better all round speakers aren't that good at any specific type of music. Speakers like the Spendors and Proacs that are not classed as 'all rounders' tend to produce far better representations of real instruments, which is what it's all about as far as I'm concerned. One of the exceptions to this is the ATC range.
But like you, I'm not totally satisified with the RS6s. The RS6s are a great party speaker and will make anything you throw at them sound pretty good and some material sounds over the top amazing. However, they do not satisfy my audiophile ear when it comes to imaging and mid-range realism. Don't get me wrong, I think they are the best floorstander for the money (by far). 'Party' speakers don't make good hi-fi speakers. The MA's midrange can't compete with the Spendors, and the Spendors will do a far better job of presenting you with real instruments.
I'm personally looking at dynaudios as my next floorstander. Either focus 220s or Excite X32s. I've got a pair of small Excite X12s now and they are absolutely amazing. They are almost a hybrid of what I like about the RS6s AND what I like about the Spendor A6s. These little stand mounters are breathtakingly realistic but at the same time, still have the energy, dynamics, and excitement.Do try the floorstanders first - I wasn't so taken with them as I was with the standmounts. You could also look at the Proacs, although based on your preference for the MA's and Dyn's, I'm assuming these may not quite have enough bass for you.
