I used both amplifiers and love sound on both as they have different character . If you prefer more tube like then darTZeel will be better but cost almost double compare to M1.1 .
Can you bi-amp the Midi Grand’s? If so can you send a picture? The reason I’m asking is I‘m looking to purchase the EMG and I‘m trying to decide on the Lamm ML3 Signature amps or going with the Lamm M2.2 and the ML2.2 on the highs
