I have stock DNA-125 which I enjoy very much. I really appreciate Zaikesman's assessment which I too feel is right on. For those of us who don't need excessive power and don't have a mega ton audio budget (and we are legion) but do want an amp that can deliver punch, dynamics and music; I think the 125 is a fine amp. There may be a few sins of ommission but few of commission. I feel no need to rush out and buy anything different. Like much in audio it takes a lot of bucks to get another 2 to 3% of the music. I can live happily with where I am (at least until I save up enough for Steve's upgrades, LOL).
