I agree, in terms of detail retrieval it is the best I've ever heard, resolution is amazing so live music feels very real and life like, microdetails just pops in front of you, lots of information coming from nowhere, bass is spectacular and the background is the blackest and I don't use any EQ at all with D8000 Pro, unfortunately I prefer tubes so I put my unit for sale but way better than Kinki THR-1 and Jotunheim 2, A90, Singxser SA-1 and other amps I had in the past
It’s just been announced… a Sparkos tube amp. It was mentioned in a newsletter email from Sparkos that I got last week .It is likely to be awesome and I consider myself on the wait list of interested enthusiasts once details emerge.
The only other headphone amp I use after I got the Sparkos Aries is the Auris Nirvana tube amp because of its synergies with the Abyss 1266, it makes the mid range very enjoyable for vocals. The Aries is still more audiophile for classical and some particular tracks calling for “air” such as something like “Tubular bells”.
