Gryphon Diablo 300 Has Arrived: First Impressions.


After a very long and drawn out search for a new amplifier for my B&W 803 D2's, which included in-home demos of McIntosh (452/C2600), Bryston (4B3), SimAudio Integrated's, and others that I tested in-store, I finally landed on the Gryphon Diablo 300. With the optional DAC module and phono board.

I feel lucky to a short trip away from one of the seven Gryphon dealers in North America, or I would not have found my amp. Some who are familiar with the Diablo may see my list of other amps I tested and think, those brands are not in the same league as Gryphon. And, after having painstakingly scrutinizing every demo component, I would have to agree they would be right. Those other brands cannot even come within striking distance. But here's the thing: from a pricepoint perspective, I'd be spending the equivalent amount of cash with those lower end brands once you factor in a pre/power amp, power cables, and interconnects - and it wouldn't sound as good as the Diablo. So, while expensive - the value is tremendous with the Gryphon Diablo 300. Others on this board have confirmed their opinion that I'd need to spend double on seperates before I could better the Diablo's performance. Including Whitecamaross, OP of the well known and ongoing "long list of amplifiers..." thread. I recognize that my search did not include uber-integrates from T+A, Dartzeel, etc. No way to consider these were I live. But I think that the Diablo is likely better suited than these alternatives for my use-case, with the power, current, and ability to drive my speakers in a large open space with a vaulted ceiling.

So I picked up the Diablo and it came in a great wooden crate that is smaller than you'd think, and has very handy clips that allow each panel of the crate to come off one panel at a time. The DAC was not pre-installed, and came in a seperate box. The phono board was also seperate, and was sold to me at a discount as it was a pulled from the shop's demo Diablo 300. I had expressed interest in installing these modules myself, so the shop said they'd let me have the experience of opening the brand new Diablo. Having installed the module and board (without incident), it was a little tricky. I would not suggest others try this unless you have some experience working with electronic components, PCB's etc (I do). And for safety you definitely want to ensure the Gryphon's massive and many capacitors have fully discharged prior to working inside.

On to the sound, out of the box with 0 hours run-time. The Diablo was a bit of a gamble for two reasons: 1) The dealer does not do in-home demos, and 2) The closest speakers I could test with to my 803's were the B&W 802 D3's, and 3) No returns or exchanges. Having fired up the amp and connecting to my digital source, right off the bat the music was thoroughly engaging. And here's the thing: When purchasing new gear over the course of 20 years or so, I've not once purchased any equipment that I've loved in the first month. This is the first. On my 803 D2's (or Diamond, whatever B&W calls this generation), I found that for the first time in all my amp-testing I was not listening for things like "dynamics","timing", "linear response", "imaging", but rather listening to people playing music. All instruments and voices have this solid and real quality to them. An example: with the tambourine at the start of Reckoner by Radiohead, you can sense the impact of each strike of the tambourine against the musician's hand. The same effect is there for vocals, with backing harmonies having a texture to them I've never heard. Another way to describe this effect is that rather than simply hearing the instruments, you are aware the sound is caused by something physical happening. Like with snare drums, it is more tangible than with any other gear I've heard. I've always thought that trailing notes or chords at the very ends of songs are just there as musicians need to signify that the song is over. But now, there is a presence and drama and texture to these endings I've never heard before. Just as I said earlier, I'm no longer listening for things like "dynamics" and "timing", but rather hearing the musical manifestation of these things. The midrange is absolutely beguiling, as one pro-reviewer put it. I think this may be partially due to the DAC based on my in-store testing I did. So far I've only tried the USB input at home. I am quite sensitive to harsh mids and highs, especially on poorly recorded hard rock, and can find this type of music very grating on hifi equipment. But not on the Diablo. The mids and highs are smooth. There is no sign of any harshness at all. But counter-intuitively, at the same time, there is so, so much detail to the music. Everything is revealed, in a presentation that is paradoxically smooth and engaging. Is this an analytical amp, or a musical amp? It's both. Don't know how they pulled it off. The bass is one of the Diablo's most striking qualities. Just as with the other instruments, the base is tangible, highly detailed and deeply textured - it creates a groove in the music that is so satisfying. I didn't know my speakers could do this.

This amp absolutely has a voice to it - it is not a "just the facts" amp. So those who are looking for that sort of amp may not like the Gryphon. But for me, this is exactly the sound I was looking for. Some have said there is a slight "dark" quality to the presentation, and I thought that sounded negative. But I understand now and have come to realize that this dense, detailed, and rich smooth voice is exactly what I was looking for.

In terms of how it performs on my speakers vs with the 802 D3's in the store - there is quite a bit of detail, and soundstaging, that is not present now. But on the flip-side, I actually like the overall presentation at home even more, and the detail that is there is still incredible. And, I'd expect more detail to emerge through the burn-in period. Even now, I'd be totally happy if this is the best it gets. In the store, I found the high level of precision of the 802 D3's just a tad distracting. For example, in the store, if I turned my head slightly, I could hear the entire soundstage shift quite dramatically. My 803's at home don't have this issue.

I have not finished upgrading accessories yet: I am running this amp on inadequate sub $1K Van-den-hul D352 speaker wire, and my source is a Mac Mini with Audirvana/Tidal Hifi. I do have it running with a brand new AQ Hurricane power cord. My Mac will be replaced by an Innuous Zenith MKIII but it's on backorder. Might be a month or two wait. Don't know what I'm going to do about speaker wire quite yet. I'd like to try Valhalla 2 just to see if it is worth it!

Overall, extremely happy. Expect things to get even better with the dedicated music player, upgraded speaker wire, and some more hours of burn-in. One more thing - I don't think that Flemming Rasmussen designed this amp. Batman did. And just look at the remote - case closed.

Mikeyaya,

No need to keep it on all the time, it takes 45m to reach quiescent temperature. 

Idle it consumes 200w, it does get hot to touch. Can heat my room up, ok for the winter.


I won't be leaving mine on all the time, although I have been through burn-in, which is done now!
Bubb the hifi market is comparatively small.  Many dealers and distributors are not selling expensive equipment on a daily basis, so I'd expect they need to make a lot of margin when they do sell stuff.  That's the way it goes I guess.....
One of the things about my room is, I don't know what treatment you could even do.  My system is literally in a wide open space.  Room corners are far away from both the speakers and the listener, and then I have the vaulted ceilings.  There are no walls nearby to apply treatment to within reasonable proximity the way things are.  Not to mention, where I live it is not like I could get anyone qualified to assess my room for improvements.  I know room treatments make a difference, as I've had unworkable rooms in the past where it was impossible to get the sound right without treatments.  But I just don't know how to go about it considering there is no one local that I could consult with and, there simply is not a lot I think you even can do with my room layout....
The difference with the cables was WAY beyond what I'd call squeezing the last performance out of my system.  Both the Transparent and Nordost cables were a complete overhaul of the sound, in a positive way!
Having heard what this can bring to the system, it is not going to be possible now to unhear this, and be happy with the sound without the upgraded cables!  As I said, the magnitude of difference was the same as I noticed with the Diablo over other preamps and amps.  Complete overhaul of the sound.  But only if power cords AND speaker cables are part of the equation.
The one thing I am doing to see if I can take SOME cost out is one more test:  Instead of using the Valhalla 2 biwire jumpers for the 2nd speaker terminals, I am going to try the Nordost Reference jumpers, which cost way, way less.  Dealer says he thinks both jumpers are just as good but have difference style of sonic presentation.

Not to worry I can advise as I have been through a similar exercise. This is what it's all about sharing knowledge and helping each other. (:-

My room correction consists of some material on the walls, ceiling, bass traps. The more you can get away with (partner dependent) by sorting this way the better. That means the electronic side of things can use its resource to fix problems that the acoustic material can not sort.

Audyssey don't make my pro processor anymore. The good thing with this processor is that I can measure 32 different points around my seated position. Or I can set up different zones. I'm going to split it into 2 zones. One for my serious listening with Diablo (2 channel) and the other for my 5.1 setup. In both cases correction is applied.

Things to look at-

1) Minidsp- For electronic room correction, uses Dirac live for room correction.

2) For room measurement, use the minidsp umik-1 microphone

3) Room treatment, many available-

The above two even help with what to apply where. If you send them a plan of your layout.

Hope this helps.

" The difference with the cables was WAY beyond what I'd call squeezing the last performance out of my system. "

I think you need to keep this in context, I meant in comparison to room correction.

Are you not going to get two sets of speaker wire to bi- wire the B&W speakers? I'm using two sets, at the Diablo end they connect to one set of terminals. I'm not sure if this makes a difference, as I've never used the jumpers.
I'm a newbie Diablo 300 owner and a newly baptized fanboy of this amp. You aren't kidding. I was listening to a piano recording of Shostakovich's preludes and fugues last night by Tatiana Nikolaeva. The performance had me glued in place, and at some point it occurred to me that I could sense the whole piano in my room. Total cliche, of course, but I've been in this hobby for 30 years and didn't know what I was missing til the Diablo delivered it. 

Of course, I made the traditional rookie mistake right away of playing it too loud, and this amp will make you pay for that. The "presence" it delivers across the whole frequency spectrum is such that it begs to be played softer than other amps. At the right volume, the low level music just seduces you and the climaxes build in an organic fashion. But you guys know all that. Just had to put my two bits in. ;<]
davidz, welcome to the club!

It's not like a normal amp as you have gathered. When quite pieces are playing you end up turning it, only to be caught out by a loud parts. You can even play low quality music through it and even those tracks are listenable, unlike other amps. It never ever sounds harsh or clinical, it has a warm organic analogue sound to it.

What volume you listening at? What's your other components?
