Singxer SU-6 Review
The reviewer is giving his honest experience with the product and was not paid to write a favorable article. The gear was purchased due to interest and enjoyment in quality of sound.
I found a deal on the Audio-GD HE-7 Singularity last year. My first introduction to Audio-GD was in 2015, when I first began my audio journey and purchased an NFB-15.32 with TXCO and Amanero USB. I was able to compare the sound with Feliks Audio Elise, and it was a satisfying experience comparing the two products. The NFB-15.32 had a fun, upbeat, more musical tone with engaging mids, while the Elise was a more neutral amp: airy, neutral, and analytical with a fast PRAT.
I have long waited for a higher-priced product to purchase and use. There were a few choices I had been thinking of: the Schiit Yggdrasil, Audio-GD Master 7 Singularity, or another one of Audio-GD's products, the R2R-7. When I saw a deal on the HE-7 Singularity; I quickly made the decision. This product was once one of Audio-GD's top of the line DACs, priced at $3,080, before being discontinued.
At A Glance
The HE-7 Singularity is built like a tank. It is 17" x 19" x 4.25", and weighs in at 37 pounds. Its design is minimal, and uses an aluminum chassis to achieve a sleek, appealing look. Though not exactly subtle, it fits on a Monolith 4 Tier Stand XL perfectly.
Here are some of the specifications about the HE-7 (non-Singularity):
The HE-7 Singularity is an interesting animal. After looking at the specifications, you get a sense that it supplies exceptionally clean power with its’ 4 R-Core transformers. When you listen to the HE-7 Singularity, it's like a similar feeling, and it seems to derive its sonic characteristics from its design.
Soundstage and Imaging
There is an absolute openness about the HE-7 Singularity, and anyone looking for depth shouldn't be disappointed. It's very spacious and allows all the instruments to have their place, with excellent decay in through notes. The HE-7 Singularity has a 3D-like or holographic imaging; I'm not quite sure how to phrase it. I've heard this term ascribed to DACs don't want to exclude it from this review of the HE-7, because while you're paying top-dollar for the HE-7, it's also a truly great sound.
The bass ties in very well with the overall signature of the DAC. It delivers and is dramatic when a track calls for it. It is tuned towards a more fun, full sound, with great extension, and complements the DAC’s other ranges well. It is slightly emphasized, but not overpowering, and has a unique character, and is definitely of quality.
The mids are on the laid-back side, and sit clearly and beautifully with the rest of the staging with sweet timbre and good extension.
The highs are very enjoyable because there is great depth and openness to backup the notes. They are also laid back, but are crisp.
Liquid, lush, laid-back, romantic and slightly warm is how I would describe the HE-7 Singularity; very smooth, velvety, yet transparent sound. One thing to note about the HE-7 Singularity is that it’s stage is incredibly wide, and detail separation is great.
It's engaging in its presentation and doesn’t lose detail. No matter what is played, everything is pulled together gracefully. There's a certain amount of air that makes it sound very high quality.
In a dynamic song, notes register with clarity and the HE-7 Singularity really puts on a show for you and shows its capability.
If you are sensitive to treble, you can rest assured that the HE-7 Singularity never fatigues, and does a great job at taming the more neutral/brighter Feliks Audio Euforia.
I found great synergy with the AMPs I currently have: the Yulong A18, and Feliks Audio Euforia. I found the best results when rolling with the EL38 and EL32. It took the holographic presentation you got with the HE-7 Singularity and brought it to another fun-filled level.
This DAC was my first experience with a high-end reference product, and as soon as I gave Audio-GD’s HE-7 Singularity a listen, it immediately impressed me, just as I would expect from a DAC once priced at $3,080.
It provides another level of sound that I can safely say is above lower-priced products. While it is far from inexpensive, I feel that it brings value to anyone's stable.
When comparing the HE-7 Singularity with lower priced products, I found that the lower priced products, such as the Schiit Modi Multibit had a more energetic expression and a bit more extension through the mids, but that’s where it ends. Across the ranges, in its large staging, presentation, and extension, the HE-7 Singularity won.
If you are in the market for a DAC, there have been reviews that the R2R7-HE is even better than the HE-7 Singularity. At this point, the R2R7-HE is the successor to the HE-7 Singularity, and if there was a reason to purchase it, it's because the HE-7 Singularity itself is an excellent DAC.
I believe it will indeed be challenging to find a product that will top to the HE-7 Singularity. It presents music with stylish softness and reels you into its sound, providing you with an ambient relaxation.
Of course, there is always more to try and experience, but I don't think any prospective owner could be dissatisfied with having this product as part of their HiFi setup. It’s a very capable end game that delivers a unique and fulfilling sound.
