Hi Zephyr, I am the very happy owner of 2 NL14+ monoblocks amplifiers purchased directly from Maker Audio. They are stunning amps!!! They are just the best amps I've ever heard in my life. Tom Maker the designer told me that he compares directly the NL14+ to the Edge Signature One.2 monoblocks at just slightly less than $40k less than the current Sig one.2 retail!!! The NL14+ have many improvements compared to the old NL designs, much more capacitance (272 000 uf), more efficiency transformers, a line conditioner built into the 2 chassis, laser bias upgraded too, transformers are 4X1250 VA, 2500 VA by block! Power provides 2 X 325 W under 8 Ohms! All the improvements provides much more control than before and I can tell you the NL14+ couple amps outperforms all the amps I have already listened in my life included the NL12.1 and many others much more expensive audio amplifiers. Every music moment with these amps is a musical magic moment. I can hear so much things never heard before.... The improvement in my audio system with the NL14+ is such that I think I have change my Eggleston Rosa loudspeakers!!!!And they are so musicals!!!I can hear each instrument from a jazz or rock or classical music band without any stress or confusion, all is open, relax and dynamic if the signal needs to....
With the NL14+, I can also hear very easily each note from beginning to end and I can better understand where the musicians wants us to go with them. Whaoo!!!, the bandwidth seems to be infinite with the NL14+, the bass extension and control are stunning, the medium and treble are just so beautiful,true and precise....At their price $12500, I think they are a amazing opportunity to get exceptionnal high end amps! My opinion is that the NL14+ are my definitive amps!!!
Hope this helps you.
