Hi recently purchased a pair of Snell J II that were rebuilt to III spec with additional silver wire upgrades some time back. As I understand this was carried with assistance from AN. In addition, they were made active with the introduction of a Meridian 101 and 105 onto the rear of each speaker providing 100W per speaker.
I have them currently hooked up to Node 2i (Tidal MQA source - DAC by-pass), via a Perpetual Technologies P3A DAC (Modwright Signature 2 upgrade) plus a Monolithic PS with a SPJ La Luce Passive Preamplifier - Pass 170.
I will play around with DAC and Pre options but first impressions are very good. Always a good sign when from the go listening to the music rather than the gear. There is something very engaging about these speakers.
