Hi guys,
I'm really excited to have discovered this site, a beacon in the night in the field of "audio mysticism" in which I stumbled when I decided to go into this fantastic world.
However, I have always considered the audiophile world too far-fetched, keeping me distant. But recently I found an incredible offer for a complete system that I coudln't resist and I bought it. The system is as follows:
-Kingrex t20 AMP + PSU
-Topping dx3 Pro + Topping p50 PSU
-Anticables 2.2 for all connections
-Audioquest USB jitterbug
-JB3F johnblue speakers
Everything was practically new, with boxes and manuals, at the paltry price of 600 €. I could not resist and I entered this world.
I purchased a short time after a Kingrex pre amp v3, further increasing the sound quality. But now a doubt arises about the source. Before I used an old Windows laptop with JRIVER, but I decided to buy a Raspberry PI 4 with Volumio, and I must say that in terms of interface and usability it is perfect. But I would like to make this little object the best, and I was thinking about how to improve it. I saw that by connecting the USB-C cable to the USB output of the Topping P50 the sound improves (compared to the Amazon € 5 power supply), but I plan to replace the Topping to buy a Sabaj d5 to also have a decent headphone output , which the Topping dx3 pro does not have (at least to drive Sennheiser HD650).
Now, therefore, passing to the questions:
- Would I have an increase by adding an Allo Signature device or similar using a COAX cable to the DAC, or are they wasted using a good DAC and therefore the USB output of the Raspberry PI 4 is sufficient? There are those who say that there is no difference because the USB is ever better, who says the opposite, and costing € 250 I would not do "attempts" ...
-What DAC could I buy that has two outputs, so as to send the signal both to the Kingrex, and to another headphone amp? Would the Sabaj D5 do the trick by connecting the first amp via RCA and the other with a balanced output? I wouldn't change the Topping dx3 pro, but all the kingrex system doesn't have an headphone output, and the topping dx3 pro has only one RCA output...
-What USB power supply I could buy to feed the raspberry? I have read that if an Allo device is added, it must be powered by two separate sources, so could I not use a single linear power supply?
I thank you in advance for your answers or for any clarifications to my mistakes.
