I have a McCormack DNA-125 and a Wyred4Sound ST 250 that I used in my main system. I find them both quite good but they have do have some differences. I find the Wyred4Sound to be a little warmer on the the top than the the DNA-125 and not quite as extended on top. The smoothness was nice but they were a little polite for my taste at first. I was able to correct that with brighter tubes in the preamp to add some sparkle. The mid-range and bass I think the ST-250 edges out the DNA-125 but not by much. I currently have the ST-250 in my system while the DNA-125 is in storage.
