I am a proud owner of Denafrips Ares II, and yes I am looking to sell this unit.
Let me share some insights on why I have taken this decision and its a complicated answer to it.
Denafrips Ares II is smooth, Analoguish and neutralish has superb soundstage and imaging, in some songs instruments flow around you. It doesn't attack and punch like the delta-sigma DACs.
You might even find it lean if the chain isn't matching.
The last thing is exactly which is missing for me, it is sounding lean and I find the low end and bass reduced by quite a bit. Mostly because prior to this I was using SMSL SU9 which is warm. Adjusting to the new change took some time.
I have RPI with Volumio, WiiM Mini > Denafrips Ares II > Audiolab 6000A > QA3050i
Someother DAC's I own or heard with my system, SMSL SU9 (still using on my desktop setup) which is warmish, SMSL SU8S, Topping e30 & D50s, Audiolab 6000A's DAC (using it).
It comes down to taste, chain and genres one listen to.
Now I have multiple reasons why I am selling, moving out, Audiolab has a good DAC.
If it is not sold I might carry it, its does sound good.
What I feel is until unless one tries a new product in your chain in your room, you won't know how big change does it make in your listening. And do you like the change.
Happy to answer more questions
Guys please do not buy a Denafrips DAC. Audio equipment sound is relative. Therefore, when we comment on a DAC, we are actually commenting on our audio system.
Anyway, I have a very modest system build around the Elac Navis ARB-51 active speakers. It sounds somewhat like a studio monitor which enables me to understand nuanced source differences. I don't have a preamp even; I control volume using HQPlayer.
When I first received the Elacs it sounded glorious even with a spare Topping D10, very warm, rich and sweet sounding. But after a few days of burn in the speakers opened up. Overtime it started behaving more like a studio monitor and made the flaws of the D10 obvious - a weak mid-range.
I changed the DAC to another cheap PC based DAC Creative SoundBlaster G6. The tonality was very good, just wanted a boost in the overall signal. So started looking for a good quality audiophile DAC with warm presentation and good mid-range body. And voila fell into the reviewer trap.
From first hookup I knew Pontus was not a good DAC. The only obvious difference from my previous cheap DACs is it has more byte and grip in the high frequencies, exactly opposite of what I expected. Nevertheless, in the region I come from, it is not easy to resale audiophile products especially personally imported products like the Pontus. So, I had to make it work.
Immediately I moved to the NOS mode and it sounded worse than anything I ever owned. The sound lacked resolution, soundstage was small, claustrophobic and there was significant high frequency roll-off, the worst part the sound was gritty and unrefined. Switch back to the oversampling mode some problems are gone, but the sound becomes V-shaped, too much bass and treble, very similar to Topping D10 a 100-dollar DAC.
The worse part of the Pontus is it has a DSP inside that does God knows what, reviews by GoldenSound on YouTube has more to say about it. To summarize with Pontus II, you will get -
1. A NOS mode that is a total abomination
2. A OS mode that sounds like any other Topping DAC
3. Sound is a little gritty, unrefined in any mode
I do not know how to call this better by any stretch of imagination. If you plug this device to any speaker, amplifier where there is any room for "aggressive expansion" the increased bass, treble and grittiness of Pontus will sound better. That is why I said at the beginning why a DAC’s sound is relative. BTW I do not know of any device in the world that will sound good in the NOS mode!
Some define Pontus as analog sounding; I feel like crying when I hear that. I have heard some good LPs and Cassette decks; standout quality of an analog system is it will never give you listening fatigue. But Pontus is very fatiguing after a while, especially if you have a transparent system like me. May be this is one of the reasons people feel the urge to upgrade.
After over a year of usage, Pontus have become even more open in the bass and treble region, the OS mode is now unlistenable, and NOS mode still have the same problems as stated before. But HQPlayer upsampling helps to some extent fix the problems of the NOS mode, but upsampling is something I never liked. But there is no other way than to stick to it now.
