Bernie,
I'd agree with George on this albeit via different demo comparisons. I've demo'd all the DSP now apart from the 6k's.

The 5200's did seem better that 5k's but, like George with his 6k's, I didn't see any 'threat' to my current 55's.

I tried a few difficult bass and mid style tracks and found that the detail just gets lost with the 52's. I think it's a simple effect of the bass and mid sharing the same amps and being a 2.5way design.

As soon as you go into 3way, the detail in this area becomes clear and was the main reason for my move from 5k to 55k.

However, I do agree that they the 7k's (and 55k's) do pack quite a punch. So, it is perhaps this that may drive personal preference over the perceived details.

I'd also agree with the above point that an 808 paired with 5200's, whilst ergonomically and easthetically very appealing, would not get the most from the 808. I'd be tempted to put the G91 into your new 2.o setup and put an 808 with your 7k's.

Tough choices hey ? [Linked Image from softronix.com]
