Nice basic amp for a reasonable price !
I just received this amp the other day. I've been using a iFI Pro iCan amp previous to this one with very good results from an Astell & Kern A120II DAP. I'm aware the 120 already has a DAC, but I decided to use my iFI Pro iDSD as the main DAC before I put it into the 789 amp, so it's really being processed twice, however I wanted to take advantage of my toslink optical cable that came with my A120II. The other option would have been to go straight in with a crude Y-type 3.5 to RCA input, but that line causes noise from ANY amp for me, and I felt that the optical cable would give a better result. Also, I already had balanced cables running from the iDSD to the 789. Without going into too much boring experimentation, I noticed that the 789 seemed ( to my ears ) to have a cleaner sound, and at a much cheaper price than the iCan. I used my AKG K812s, Focal Elex ( I'm not suggesting that you need these ... just used them as a reference point ), and a pair of Senn HD 820s. The 789 has a clearer sound than most amps at this price range. I wanted to give my impression to help those standing on the fence deciding to buy this or something else. I'm not planning on returning the 789 unless something goes wrong, but do I wish this amp had come out before I bought the iCan ? ... Sure !! Also, the 789 does not have a lot of bells and whistles as compared to the iCan, but honestly the 789 is really your basic amp, so unless you're looking for a lot of options on a desktop component, then this will fill your need for an amp. The K812s are the most neutral as far as sound quality with this setup and the 789 in the connection. There's a warm somewhat colored sound to the Focals, as well as the Senn HD 820s. I'll have to work with the 789 a little longer to get a true picture of its ability, but for now I'm pleased with the performance. Z Reviews has done a video about this amp, and goes into a little more detail on YouTube. Hope this helps. PS ... I failed to state that my iDSD DAC does process Hi-Res files ( WAV, FLAC, or AIFF ), so if you need that type of processing ability you will need a DAC that can accomplish this.
Would recommend to a friend.
