Hello Frank, Mary, Dan, and everyone.
I recently purchased a pair of M225s pre-owned by someone in Texas who bought them new, and I'm very happy with my purchase. I live probably a dozen miles from Frank and Mary, so in some ways the amps have come home.
The M225s replace a pair of Schiit Vidars I ran in mono. If you're familiar with the Vidars, you know that an XLR connection is required to run them in mono, so the M225s slid into their place in about three minutes. I'm extremely happy with the sound. The details across the spectrum easily surpass the Schiit gear. I listen to a really broad range of music, including choral music, which can be difficult on amps. The M225s handle my most difficult choral tracks with ease.
I'm running Lumin U2 Mini --> Gustard X18 DDC --> Denafrips Pontus II --> Benchmark HPA4 --> Van Alstine M225 --> Harbeth P3ESR in that setup.
Anyway, just thought I'd say hi and give a shoutout to the team for making some really sweet gear.
