Edge NL 10.1 update

for what it's worth, I had an NL-10 for ten days. I let it run in on a satellite radio music station for seven days continuously while I was away. It was brand new, unopened box, ready to go. I was eager to try this amp at home and was happy to have the chance. I came home, sat down to listen and it was the single worst sounding amp I have ever heard. It was lifeless, no depth whatsoever, none of the typical amp adjectives even remotely applied to it. I kept listening and asking myself "what on earth is going on?" Everything I played sounded small and like those solid state amps from the 80s. I sent it back.

Did anyone at Edge check it out? Was there just a problem with that unit?

I have the 10.1NL too. Amazing amp IMO. I replaced my Pass X-600's with it. What does the upgrade cost and what do they do to it?

The cost is $3200..not sure all they do. They rebuild circuit boards with better, matched components. Supposed to be better than SE upgrade.

For Huntermusic-

Years ago, we were sent a new Edge amp, an M-10. We had already been quite happy with that model and needed a second one for speaker-burn-in/testing. Hooked it up and no bass, no depth, lifeless. So, we decided to run it HARD for a full week 24 hours/day, on obnoxious bass-heavy music. The result- still no bass. A pair of speakers with 12" woofers sounded like very small two-ways.

We spoke with Edge' designer and he advised turning that amp off and on 10-12 times over the next 48 hours while playing our music. Voila! Earth-shaking bass, and all else fell into place, sounding exactly like the other M-10 we'd already been using.

The designer's explanation was that the turn-on surge of current helps to 'form' the (large) power supply capacitors. Since then, any new component we obtain always has its AC power turned off and on at least 12 times over the first few days of its use, before we let it run non-stop.

In the case of the Edge amp (and other amps), we let the music continue to play in order to know the power supply is discharged completely (the music fading out), before we turn the amp back on. Although we use other amps, we greatly enjoy our current custom NL12-based Edge amp.
