    Yes, the MKIV is the best looking A77 by far IMO.

    Beautiful unit. How would you say the sound differs from a B77, especially those that do 15ips?

      The A77 sounds warmer and more tape like. Best sounding but most ugly of the A77s is the Mk1 IMHO. The B77s look the nicest IMHO but sound a little thin in comparison (electronics were revised but with an improvement in design and reliability/cost, but detrimental to sound quality if you seek warm tape sound quality).

      @@delatronics3257 This is exactly the response I was hoping for in terms of sonics, thank you. I'm considering A77mkIV in good shape but it doesn't do 15ips, but noticed (at least on TH-cam) how great even 7.5ips sounded. A dealer I recently met is suggesting I may be happier with the Otari 5050Bmkii. A lot to wrap my mind around but this is helpful.

      Depending on what model you have, this may be normal. Try setting the obter ring on the level controls to another setting.

      I like Curitiba but the current government is terrible since Lula got in. I'll most likely be back in England this year. I Plan on servicing stuff again.

      This is party true, but until you've bought a batch of used recorded on tapes on ebay and discovered an old gem of audio from the 60s or 70s, realise how silky smooth the tape sound is compared to horrible sounding MP3s, you'll never know the beauty of analogue tape! Your personal opinion is noted however, and I respect that.
