When I received the Studio-V earlier today I did listen to it very briefly and noticed the difference between the Studio-V and the Rocco-P, but wanted to charge it up completely before I spend some more time listening.
Many hours later it was still charging and had only reach three bars, so I just couldn't wait anymore. I don't know why it takes so long to charge or maybe the bars doesn't indicate the correct charging level, I'll figure this out later and let it charge again overnight. The good thing is that with the long battery life I won't have to charge it very often.
Now I have been listening back to back with both Player's with their respective default firmware.
Only with IEM's, RE262/EX600/reshelled TF10 and DB-02. AAC 300vrb, same albums on both players.
It was easy to volume match the two players, because the volume level are the same, to me at least, maybe just half a step difference.
The sound difference I found is fairly obvious. The Studio-V sounds warmer, Rocoo-P more leaner, no surprise..
Now, I will point out that I really like how the Rocoo-P sounds, very detailed etc., and overall a great 3-D presentation.
With the Studio-V there's just more, the 3-D presentation is not just great, but very great. Particular in the front-back. There's just more depth and I feel like I just want to be absorbed into this deep space and forget
about anything else, very nice.
There's also more bass impact with the Studio-V making it sound more musical than the Rocoo-P.
Even when listening to the two players at the same volume and with IEM's. I can hear that the Studio-V sounds more powerful and has more quality to cringe out, like it's almost craving of for to go out and purchase some expensive headphones, but I know my wife won't let me unless I buy her some kitchen equipment as well.. I think "the people who wears headphones all the time" will enjoy the Studio
All the IEM's I just used, I all found to sound really great with the Studio. I'm not very sensitive about hiss, but didn't notice any more than already was present in the recording, same level hiss with both players.
My troublesome TF10 that hates high impedance output sources/amps seemed to behave rather nicely, but I have to go back and compare with a source/amp with low output impedance to make sure what I briefly noticed.
Again, this all with default FW's, sound can be altered/tweaked by experimenting with these, but keep the Rocoo FW with the Rocoo and the Studio FW's with the Studio. You don't want to brick your precious one..
Okay that's it for now. Brief impression out of the box. I know burn-in may improve/change both units, I still don't have that many hours on my first arrival, the Rocoo-P, but if there's improvement to be experienced, hey, I'm all game.
