Nilai vs Purifi
(different volum, you need to adjust)
First track
Nilai: More detail, spatious. More neutral. Swe
et. Smooth. More musical, credible...
Purifi: Voice predominant, more congestionated
(vs Nilai). More bass, too much.
Trebble more annoying.
If you do not have the Purifi, the choice is clear to me <- Trebble more annoying.
Second track
(piano)
Nilai: I take my hat off! Wowww.
Purifi: Nope, much worse.
Congested. I do not like!!!
Third track - agggggh,
bad music
Nilai: Much better than Purifi. Same impression as with the first.
Purifi: Voice predominant, more congestionated
(vs Nilai). More bass, too much. Without problem with trebble. Too much bassss.
In short: Nilai, among other improvements, has corrected the usual weakness of Class D amplification with high frequencies
(real instruments, acoustic or electric).
