Threw a lot of big classical on demanding playback levels at the NL14 yesterday and today. At only 250 hours or so, this amp is opening my eyes further to the changes it brings. It has taken everything I've thrown at it in stride and rewards with very musical sounds, great imaging and overall and very impressive experience. Don't have time to write more but "HOLY SH%^& What an Amp!" comes to mind no matter whether it's rendering subtle violin, piano, sax, flute, vocal or other delicate passages or is in full-on assault mode for any of the most demanding material I've thrown at it. Tom Maker has done it again and even better than the prior NL12.x and Sig One generations!
