Intg Amps: Hegel 590 vs NAD M33 Masters vs Gryphon Diablo 120


Hi All: I am getting an itch to upgrade my integrated amp from Hegel 190 to something more robust that facilitates future speaker swapping.  And no, I'm not presently interested in separating components that much further (e.g. separate DAC; separate amp; clock; etc. etc).  I mainly interested in the following 3 on a used basis:

Hegel 590 OR NAD Masters 33 OR Gryphon Diablo 120

Max budget is $7500 if I choose to go towards the Gryphon (used), but curious if it's really THAT much better.   I'm particularly interested to hear from people that have had or auditioned at 2 out of 3.  The room correction on NAD is very appealing but I quite like my Hegel and it's tight control, and so something nice about staying true.

 

Current Setup:

* Unideal Brooklyn Apartment living room into Kitchen

* Hegel 190

* Monitor Audio Silver 7G 500

* Pine Tree Audio Cables

* Dual 1216

* Schiit Mani 2 (though I hear the phono preamp on some of above may make this superfluous)

* Spotify/Tidal (main streaming source)

My journey started as a vintage/listening to vinyl rig and I’ve slowly been updating as my usage/wants have changed. I started with a completely restored Yamaha CT-810/CA-810 amplifier streaming music from a Node n130 through a Denefrips DAC. My vinyl source was a Music Hall 9.3 with a MC cart with a Vincent PHO-701 phono amp. I decided to try to upgrade the amplifier and possibly simplify my setup with the NAD M33 as an all in one. I started streaming some high res music and I was disappointed with the NAD. It truly didn’t sound nearly as good as my vintage Yamaha integrated amplifier. I thought maybe the Denefrips DAC was making the difference but even plumbing the node directly into my old Yamaha it was still way better. I then went to the Hegel 390 and this was clearly better than the NAD for my ears anyway. Funny thing is that in the end both the Hegel and NAD were returned and I ended up with another Yamaha. An A-S2200 now holds down my shelf.🤷🏻‍♂️

 

This was a long way to go to say I didn’t like the NAD right from the start.

@marcyun I met Rune Skov of Gryphon at a demo, he said that all Gryphon amps are very neutral, except for the Antileon and Diablo 120 which are warmer, rounder and a bit colored.

@bigtwin how much of a difference did going from the H590 to H30 make exactly? I see that you have them monoblock configuration in your picture?

I had H590 and downsized to H390, did not see a big difference in my space. The same formidable detailed sound. I would change your speakers though. I had great resutlts with Dynaudio and Stirling (Harbeth like).
