Lil' Knight, do you have a good speaker amp you can use? If it's the case, the Stax transformer boxes are nice budget option. I thought the O2 sounded better out of a SRD-7 Mk2 (using either Cambridge 840A or Quad II as speaker amp) than a SRM-T1 or SRM-007t. By "sounded better", I mean it had more dynamics and punch and it had a less sleepy sound than with the tube amps, with the sacrifice of some microdetails though.
