@steve59 I can save up for that crazy KRELL since I have a KRELL Duo 175XD available for the short term for the Blade 2. I tested this amp with my prior harder to drive Thiel CS3.7 and it was excellent.
I would normally never consider such an amp expenditure since there are many other great choices at much lower cost. However, the KRELL 175XD is pretty fantastic and so I will be giving the KSA 400i a good look. The biggest drawback for me is the 25-iinch depth of the casework. I think that is a deal breaker with the wife.
I do think sanity will prevail and I will most likely buy the CODA #16 for the Blades and return the KRELL 175XD to my office system.
@jn Thanks.I heard those amps with maybe Wilson. It was a dealer system that had 4 subs stacked on top of each other. Rather nuts.
