Hi Jaap, thanks for the logical respons. Especially as Alpha-audio it is hard to make statements on products when circumstances are that different.
One remark on comparing digital on vinyl. I my opinion it’s certainly possible as long as the master used are basically the same. E.g. “Mobile Fidelity Labs recording – No one Cares – Sinatra” sounds very similar on my high-end analogue- and digital- front-end although both have their characteristics.
I hope to meet you and Yung (and others) again at one of the coming Audio – Shows, to talk in more detail on this and am very thankfull for the already “legendairy” and unique LIVE-sessions you are hosting as Alpha-audio team.

Hi Jaap, thanks for the nice review and Peter van Willenswaard, I met him more than once on the A&T demo sessions in the past. As expected the Grimm PW1 beats the Primare R35 which is pricewise more than 3x cheaper. How would you compare it against the Moon 610 LP (6.7KEuro and even the 810 LP (12.5KEuro) which you tested September 14, 2021?
Another question, as asked earlier to Yung testing the Le Son LS10 MK2. You remarked on the Technics SL1200 MK2 sound with Le Son LS10 MK2 but not on the STD with Le Son LS1 MK2 combo although you mentioned that the LS10 brings just that little bit more than the already fine high-output Le Son LS1. Was that using the STD?
Last question. Would you say the PW1/SL1200-LS10MK2 combo betters a 8KEuro streamer-dac combo or will that be close call… Thanks in advance for any reply!
