My Gustard R26 R2R DAC is burned in and have some final impressions on it (bar a clock which I'll be adding in a few weeks).
TLDR:
It's a fantastic DAC. It is incredible value for money.
Is it beating all the top of the line DACs out there that's claimed? I am skeptical but I don't have those to test with me.
Biggest thing it does - at this price point, is it changes the price to value equation when considering the bigger DACs in town. Is the sound difference vs say a Pontus II going to be worth another AUD$1000? It's for others to say, but the disruptive thing Gustard are doing is selling a v high quality piece of equipment at this price. It's a great landling point for mid-fi systems like mine.
DACs Compared (blind tested): Zen stream / Burson Conductor 3x GT (in DAC only mode, and in DAC + Preamp mode) vs Mojo2/Poly 2 vs Lan / Gustard R26
System: Willsengton r8 tube amp with upgraded tubes -> Buchardt SK400 MKIIs and Hifiman Arya’s
Pros:
- Sound (R2R ladder / OS) - is very good. The filters (Fast / Medium / Slow) made a good difference to tune the DAC to my rig (I settled on Fast).
The Gustard has better base extension, timbre, soundstage depth relative to mojo 2 / poly 2. Burson was a distant 3rd really on all tests.
- Sound (R2R ladder / NOS with HQ Player). With HQ player, these qualities remain, but the shimmer / air in the top end is really something (to my ears) and it pushes further ahead of the other two DACs. Interestingly, I found the base extension advantage lessened on some HQ filter settings which makes me wonder whether the native PCM filter is what's driving the bass impact.
- LAN input - this is awesome, I think it outperforms slightly the other inputs. (Others have had other experiences here I know). The convenience of this is really good. Roon finds it straight away. HQplayer running via LAN is my preferred set up now similar to Jake. Really adds to the picture (though HQ player can be a little particular)
- Clock - this is intriguing. Not yet tested.
- I tested movies with the DAC and experienced no sync issues for me on audio / visual (via USB).
Drawbacks / Things to watch out for:
- No idea is this the 'giant killer' that's been claimed. While it beat the Mojo by a fair degree, it's not 2x the DAC the mojo is. It's a good 20-25% better maybe (though they have different strengths). I am still a little skeptical of some of the claims. However, I suspect (and it would be nice, given I am invested) it will at least come close to those other DACs.
- HQ player set up is not perfect. Without HQplayer, life is a wee bit simpler - turn on the rig and your playing music straightaway via Roon. With HQ player on, I find i need to sometimes reset HQ player (which is on a MAC away from the audio set up) first thing in the day to get it to talk to the Gustard. After that it works perfectly for the day (not sure if a gustard or HQ player thing). When a/b testing, I couldn't switch back from HQ player via LAN/DAC to just the LAN/DAC, without restarting the machine (this is an edge case scenario, can't imagine anyone really needing to do this often).
- Menu system and the general software side of things is OK - not great. While the DAC finish and internals are good, software side feels more Topping end of town when it comes to the menu system / software. I haven't had any issues but it's not premium like other models
For many mid-fi rigs out there, like mine, I think the Gustard is going to be one of the best price / performance DACs out there. I think that’s why people are so excited and why the hype train has been good for this DAC. With other DACs I have tried in my system (with the exception of the chord dacs), there's always been something 'off' about the sound, this is the most engaged I have been in the music to date. It's a highly recommend from me (but don't necessarily expect the world from it).
