I have a pair of M2s, M22tis, and had a pair of M3Tis. I walk a lonely road here, but I prefer the M3s with or without a sub to all the M2x series speakers.

Sounds richer ... better mid bass, better bass, better for jazz, and female vocals. Can get a bit chesty with male vocals.

If you won't have a sub for a while then IMNSHO there's no comparison. M3Tis.

Best regards and g'luck.

BTW, M3s are a perfect speaker for a nice SET 5wpc tube amp.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
