Hi guys, I'm planning to buy Cayin N6 and I also consider the Cayin C5DAC option, and wanted to ask your opinion. I already bought a pair of Sennheisesr HD650 and have a smartphone. I mostly listen to my music from the phone (Xiaomi Mi Note with a built-in DAC on board) through Sony XBA-H3. I'm basically happy with the setup, but since recently I started thinking about more serious sound. I like listening from phone because it has Google Music subscription, can scrobble etc. So my question is: Would there be any noticeable sound difference between the following setups:
N6 + HD650 or phone + C5DAC (connected as DAC via USB port) + HD 650. My major doubt revolves about the understanding that I basically don't need a standalone player due to its limited functionality, but I want the best source for my HD650, and since I can connect the C5DAC to the phone I can keep all the bonus features of a smartphone there is no reason to go for a more expensive and limited option of the N6 DAP.
Thank you in advance for your opinions and answers.
Or if I pair N6 with C5DAC would that be even greater option?
If you want to compare the quality of DAC, then N6 will be at least a league above C5DAC. N6 is our flagship portable electronic with 2x PCM1792A, and C5DAC is our workhorse design with ONE piece of PCM1795. If you compare the specification of 1792A vs 1795, you probably notice their digital capability are similar, but the devil is hidden in the detail, check out the analogue detail and you'll notice how 1792A excel in dynamic, crosstalk and THD+N values, so you are comparing two flagship chipset vs a workhorse chispset for that matters.
If you want to compare the driving capability to handle 300ohm headphone, then C5 >> C5DAC > N6
So we have three combinations here.
N6 + C5: this is the recommended setup if you insisted to drive the HD650 with portable equipment, you have reasonable audio performance in terms of detail, soundstage and liveliness (an important factor to determine whether HD650 is driven satisfactory)
Smartphone + C5DAC: a good causal listening setup, you won't feel something is missing to start with, but if you listen carefully, the "density" is the weak link, the detail is not enough to fill up the soundstage created by the headphone, and the music is kind of lacking in emotion, some audiophhile elelements such as body, imaging are also lacking to some extend.
N6 driving HD650 directly: you can have explore the sound signature of the headphone, it can be very loud, but far from the satisfactory performance of the HD650. I'll describe this can "listenable" but not enjoyable, especially after you heard the HD650 with a proper desktop system at around US$1K range. The soundstage is clamed in the middle, lack in control, and music is a bit too dark for my taste.
To be honest, with full size open headphone like HD650, desktop system actually offer better value for money, the "watt" from portable device might be enough to drive the headphone to deafening level, but you need current to control the headphone and this is where the fundamental different between battery powered and AC powered amplifier kicks in. However, if you must go for portable device, I'll recommend N6 + C5, or even the new N5 + C5 can works pretty well too, but the N5 maybe be a bit difficult to come by, depending at your location, our US sales channel is still looking forward to their evaluation sample before they make up their mind.
