I decided to jump on this "Jolida issues" train and post some of my personal notes in order to help & inform my audiophile friends.
Well first I have to agree with Mwilson & Jupiterfish on a manufacturing issues. I owned 502b for a less than 4 months and had to let go due to a couple of issues that I discovered straight from the box. Purchased brand new, amp came shipped in double box nicely packed.I removed the amp from the box & discovered that the power switch blue led is hidden inside the amp instead of above the power switch, so when you turn on the amp it glows blue light from inside.That was easy fix.But paint on the surface of 1k amp shouldn't be so rough and it shouldn't include human or brush hair visible right next to where the tube holes are! Also some of the openings(small holes on the bottom of the amp) were so roug/sharp and almost dangerous looking.And sound of the amp is what you pay for.So don't expect anything close to Cary, Rogue or Quicksilver.It will paint a tube picture for you quite well but nothing stunning will came out of that box.I would suggest buying it used or hearing/seeing it first before any final thoughts on purchasing.Beleive me, there is sea of other models and companies who will offer more for far less or same amount of money specialy if you buy them used from your local Audiogoner.And for the end please inform yourself before any purchase.It will save you some money and a lot of nerves.Thanks and happy listening.
