Recommendation for Improvement over McCormack DNA-225

I currently have a McCormack DNA 225 mated with a VTL 2.5 and Line Magnetic 502 DAC powering my Salk Veracity HT3's. I think it sounds really nice but can definitely have some top end harshness, especially at the volumes I like to listen to.  I consider the Salk's are fairly power hungry in the low end (as confirmed with Jim Salk), can anyone recommend a SS amp with as much grunt as the McCormack in the range of 2K plus or minus.  Sure I would like a Pass or Ayre, but those are way above my price bracket.    I've tried Bel Canto Ref1000 mono's and Van Alstine.  The DNA had a better mid range presentation and better bottom end than both, no comparison.  Any other recommendations shy of the DNA 500, which again is over my price range.

@dwolek  I have a DNA-1 Deluxe in my system.  I too thought it a bit harsh in the high end and contacted Steve McCormack at SMc Audio about having it modified.  That was quite a few years ago and I am listening to music through it as I type this message to you.  Steve will admit to you that some compromises had to be made with the stock amp to stay within a certain price point.  My modified amp has not a hint of harshness.  There is a richness in a true to life sense and amazing soundstage openness.  And yes, the speed that originally attracted me to the DNA design is still there. Rather than purchase an entirely new amp. at least talk to Steve.  You will have to invest some $ but far less than a comparable new amp.

Good luck!

If you already have a dedicated line and a PS Audio outlet, I would talk to your tech guy about upgrading your amp.  It's amazing what thoughtful circuit modifications can do for the purity of your amp's sound.

After re-reading my previous post on this issue, I want to amend.  I mentioned "harshness" in the treble.  I should have said an "over-emphasis" in the treble with the stock DNA-1 amp.  Steve's circuit modifications evened out the frequency balance, opened up the soundstage and revealed a smoother, more life-like texture to instruments.  The difference is amazing.  If you have a specific budget to work within, it can't hurt to call and talk to Steve and see what he can do for you.

All the best!

@dwolek  Agree with audio717.  

The McCormack basic amp is a solid well laid out design.  Steve McCormack is easy to talk to.  If you call him and explain your sonic goals for your current amp I am confident he can come up with a reasonable course of action for a modification rather than selling your  current amp at a loss and buying a whole new piece of gear.

If for whatever reason you just want a new amp then this line of advice won't help.  I wish you the best in making what can be a challenging decision.

@audio717  What brand and quality level of fuses did Steve put in your amp?
