I am happy to report they are currently 15% discounted on Amazon. After a few hours of rediscovery of old classics (Harvest, If I Could Only Remember My Name, Deja Vu) from the West Coast 1970’s, an added benefit of these Truthear is to be revealing but never harsh with analog master sources. The harmony of voices is never sibilant, the electric guitars fuzzed the right amount. On a comparo with the Fiio IEM tested by Amir (at six times higher price) the Truthear here reviewed are indeed superior in the pleasure I feel listening from these old recordings. FLAC files, Topping M50, E50 and L30 II chain. The M50 btw allows me to play a large collection of my FLAC files (still working of transferring more than 12,000 files as this seems to be, so far, the limit from the SSD 4TB unit attached to the M50) stored on my nightstand. I ordered a second pair of Truthear w discount tonight.
