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.

Agreed, so far, changes are subtle, and as I said unlike most gear I've bought in the past, the Diablo sounded great from the moment I plugged it in and tried playing something.  It is not like the changes I am noticing are large, and if I wasn't playing the same 25 tracks on repeat I doubt I would have noticed.
One of the amps I tested was the Bryston 4B3, which I had purchased from a different dealer who said they don't do in-home demos but that I could return the amp within 30 days for a full refund.  I warned the salesguy at the time that I would almost certainly be returning the amp after trying it, but wanted to compare with others like McIntosh and Simaudio.  He said no problem at all!  I bring up the Bryston as I believe in the manual they stated that the amp was burned in for 100 hours or something like that (can't remember the exact amount but it was large).  However, I did actually notice very large improvements over 200 hours of burn-in time, despite the fact that it was significantly burned in at the factory.  I've heard some people say that even after burnin, Brystons take hours of use before they sound their best, and it appears that the length of burn-in period may be equipment-dependent.

Too bad I couldn't support these other dealers that have been so helpful loaning me demo equipment (or offering 30 day full refunds), they seemed only too happy to do that for me.  But they didn't offer Gryphon, so....  It was funny, one place had never heard of Gryphon and the other had, but didn't really know anything about the company or products.  My local shop (that didn't sell me the Gryphon) was admiring all the internal photos I took when I was installing the DAC and phono board, and noted how well-made everything looked.  They said they doubt I'd ever need service based on the pictures.  I brought in the remote to show them too.


Just an update:  sound has continued to develop (The Diablo is up to 50 hours now), albeit very subtly now.

I wonder if the large class A bias of the Diablo 300 integrated contributes to a shorter burn-in period.  My non-expert theory is that since the transistors never turn fully off in a class A biased system, current is always following through the system when it is on, regardless of whether there is an input audio signal or not.  This maybe contributes to a shorter burn-in?

nyev,
Have you tried different powercords yet or are you still burning in the Gryphon?  Everything still sounding good?
Hi Rshad, I am up to 100 hours and everything is continuing to sound fantastic. To be clear, it is not only the amp that is being burned in, but also the DAC module and the AQ Hurricane cord. I don’t know for certain whether I’m continuing to hear any improvement or not, but it doesn’t matter what I play, it just sounds engaging, satisfying, and highly detailed. The sound is incredibly welcoming and inviting. I will note two other cool things I’ve noticed. First, when leaving the “sweet spot” in my listening position (standing up or walking around) I’m fairly certain that the difference is smaller than with other amps I’ve tried before. In other words, with the Diablo the sound doesn’t really degrade as much when moving around. Another thing that is very unique: All the qualities in the sound that I mentioned are there regardless of the volume level. Even when playing music quietly, you can hear really full and highly detailed tones, including bass. I’ve never tried any amp before this that maintained all of its qualities at low volume.

The tiniest critique ever would be that I notice on occasion, when playing music that is quiet or during a quiet passage, and I adjust the volume up or down, I can hear a very subtle pop sound coming from my speakers. It is not really that noticeable and it only happens sometimes. Not really an issue for me but thought I’d mention. Could be related to Gryphon’s two-resistor volume control design? I believe that each volume setting switches to a different resistor or something like that.

Regarding power cords, I’m not planning to try out different brands of cords. Based on yours and others experience I’m just going to stick with the Hurricane. Which apparently requires 400 hours to properly burn in. So I’m only 25% there. When I’m there I will compare with the stock power cord to see what kind of difference there is. In a bit I will see if my dealer can bring in demo Valhalla 2 speaker wire; I am very interested in how these will sound. People describe this wire as similar to how I’d describe the Diablo’s sound - a hair on the warm side, musical, engaging, and loads of texture and detail.

When my Innuos streamer finally arrives (hopefully in early May), I may experiment with a lower end power conditioner to help manage any noise it may introduce on the AC line that is shared with the Diablo.

In short, I am enjoying this amp so much that I find myself wanting to buy another just in case something happens to it after it is eventually discontinued. Just craziness as I can’t afford that. But seriously, if I had to choose a different amp I have no clue what would even come close to the Diablo. Maybe the D’Agostino Momentum integrated but that is far more expensive.  But I have not even heard the Momentum and part of the reason I think I like the Diablo so much is that the sonic presentation and voicing matches my subjective tastes.  So maybe I do need to save up and buy another!  Flemming has retired so who knows if Gryphon can keep improving on the design or not....

I have enjoyed reading this thread. Good to learn that the new Audioquest Hurricane PC is to your liking. The Tornado model is excellent as well. If an opportunity to hear these power cords plugged into an AQ Niagara conditioner- go for it!  Keep assessing, evaluating and writing findings.
Happy Listening!
