McCormack DNA 500 vs DNA 225 upgraded


I am looking for some feedback on comparing the stock DNA500 to a DNA225 upgraded by Steve McCormack. There were a few posts that only touched that subject. I am thinking about adding one of those amps to my system and relegating the HT5 to the surrrounds and center.

The DNA500 has amazing reviews, as the DNA225 upgraded also does. Is there a benefit to either one? I notice at this point there are no upgrades available on the SMC site for the 500. I imagine the cost for either is similar.

Thanks again for any help. This forum has been outstanding for me to learn from.

One benefit of the DNA 225 over the DNA 500 is the input impedance. I owned the 500 and the 10k ohm input impedance limits your choices of tube preamps that won't result in an impedance mismatch (rolled off bass and highs). The DNA 225's input impedance is 100k ohms so it matches with a wider variety of tube preamps (output impedances). I've learned through experience and through the benefit of experienced members here.
