I've been enjoying the new Gilmore amp for the past couple of weeks. The tonal quality is slightly rich and not thin-sounding as my old, but reliable headphone amp. It's also not muddy sounding as it conveys wonderful detail in my Mad Dogs 3.2 version. I was hesitant in buying it as the audio blogs complained about the brightness in the earlier version from years ago, it certainly not bright at all to my ears. Dan, thanks for your recommendation!
