i want contribute with a comparison i made last month with the Aira TR-8 (in 808 mode) and nepheton (808 clone from d16 group) . I don´t have a 808 of course but i think nepheton is prety prety close to original to the Roland TR-808 , so i did a comparison between both (Aira TR-8 and nepheton) . Briefly, TR-8 sounds very nice especially in Kick, snare and claps (amazing and prety close)… rest of the sounds are decent but not so close , not so “warm” like Nepheton, specially in hi hats. Thanks you , hope you like my comparison :
