Have you been enjoying your Gryphon Diablo 120 integrated ?

Give it some time to warm up/burn in. If it hasn't been used for a while it should sound better after a few dozens of hours or perhaps even after a few hours, hard to know in advance. What power cord do you intend to use with it ?

I am really happy with my Gryphon 120 - I've had (and have listened to) quite a few respected integrated amps, but I haven't listened to the 300.

It sounds as good as it gets in my tiny listening room, hooked up to Harbeth Super HL5plus XD - I listen mainly to vinyl, and the phono module is also exceptional.

I would be using the Acrolink 7N-PC9700 on it. Will try Acrolink 8N-PC8100 on it too to compare. The dealer suggested to plug it in directly to the wall instead of the power conditioner, and that’s what I’m going to do.

Gryphon Diablo 120 and Harbeth must be an excellent match. Gryphon's phono stages are always excellent.

There is no used Diablo 120 for sale, otherwise I would have bought it. Can’t bring myself to buy a new one at full MSRP.

I owned the Harbeth Super HL5 Plus, not the current XD version. I can expect any Harbeth speakers to sound good with upfront and dynamic amps such as the Gryphon. I used to pair Naim with Harbeth, now it’s the Naim with Graham LS5/9.
