The A1 arrived safely with me. The device was really well packaged by you and is visually in perfect condition for its age! In the meantime I have carried out some listening tests (with my rather modest components: Nuber nuWave floorstanding speakers, Dual 704 with Vinylmaster Silver and Technics Sl 1500 with Goldring IGC 910). In comparison, my Yamaha A-960, which has also been overhauled, can't keep up. The A1 reproduces the sounds extremely cleanly and precisely with great depth and pleasant dynamics, really great sound! More quality than I expected.

The parcel arrived safely today. The packaging itself was simply second to none and the turntable is in excellent condition as described. I set it up quickly, the cartridge alignment was perfect, everything seems to work flawlessly. In short, I'm really impressed so far! I hope to play some more records this weekend and report back.
