Hi Toku,
On the other thread you wrote about the P5a vs PA3s , can you tell us more?
Thank you.
What you want to know is a comparison of functional behavior?
Or is it a comparison about sound quality?
In terms of operational function, neither PA3s nor PA5 have any problematic symptoms.
1. There is no pop noise or click noise when turning the power on / off or switching the input.
However, if the AC plug is suddenly pulled out while the power of the PA5 is on, noise noise (his noise) will appear for a moment.
It may be annoying when you use the master switch to turn the entire audio system on and off all at once.
However, the level of noise generated is not high.
2. In both PA3s and PA5, noise from the speaker when there is no sound cannot be heard even if the ear is in close contact with the speaker unit. (When using 89dB speakers)
3. The heat generated by the PA5 is a little warmer this winter season, but in the middle of summer the heat generation will be even greater and the slits in the case will be effective. It is a fever situation similar to AIYIMA A07.
PA3s, on the other hand, do not feel fever.
4. It is pointed out that PA5 has a low gain, but it is not a problem for home use in the test in combination with E50.
In the sound quality comparison,
The PA3s don't feel much different in sound quality from the SMSL DA-9, SAO200, Sabaj A20a, etc. that use the same MA12070 chip, but the PA5 produces a different dimension of sound than these amps.
The biggest difference I felt when I first heard the sound of the PA5 was the spread of the sound stage.
Furthermore, the energy feeling of the bass, the transparency of the mid-high range, and the resolution are improved, and each sound is well separated and heard. The background feels darker and quieter than ever. When you hear this sound, you are fully satisfied with the price of PA5.
However, it may not be suitable for those who like tube amps and traditional AB class amps.
How you feel the sound depends on the individual. Also, if you keep listening for 3 days, your impression will change. These are my extremely subjective impressions. Depending on the listener, the evaluation may be the exact opposite. Therefore, please understand it for reference only.
The best thing is to buy it yourself and compare the sounds. I don't think it will disappoint.
PA3s and PA5 are amplifiers with different personalities. So I am currently using PA3s and PA5 together.
