McCormack pres/amps and Steve's mods


I have a DNA .5 Rev A and absolutely love it. I may never part with it. Right now, 100wx2 should be plenty for the nOrh mini 9.0's I have coming. But what happens when I want or need more power? Do I go with a matched pair of DNA .5 monoblocks, or a DNA-1 Rev. A?

On that note, does a DNA.5 Rev A sound the same as the DNA-1 Rev A or DNA-2 Rev A?

And what should be the next upgrade based on the nOrh speakers - having Steve upgrade my stock RLD-1, or adding/upgrading the amp?

It's nice to get an idea of where my upgrading will go so I can set appropriate savings goals. :)

Given the extra dough, I'd love to have a clone to my DNA-225 to do just that.
Ditto 4yanx comments about Steve Ms customer service and good advice. I've moved into a much more estoric beast (tube otls), but my 0.5 Rev A+ was a pretty damn impressive amp.
Swampwlker - we have some things in common. Dont you have a Berning?

I went from A DNA-1 Rev B (and a short period with an Ayre V-5x before settling on the Berning.
You are right, Artg. I do have a Berning and other "true" OTLs. Still trying to make up my mind.
Steve McCormack, it is always excellent to hear from you! The mono blocks really do make alot of sense. I would think they would be the final solution to an great sounding system, as many audiophiles will agree. In regards to the vertical bi-amping, I have a question. I have biampable speakers. Once the bridging straps are removed the maximum output power to the high frequency drivers cannot exceed 50 watts & the low frequency drivers 100 watts. Can I safely drive these different drivers with the same output power? If not what are your recommendations? Thanks
