Historically, the Emotiva preamps have been somewhat warm and close-in sounding. The amps have been very fast and dynamic, but bright and harsh. This can be fixed by fuse upgrades sometimes (Furutech or Isoclean). However, they are not the best equipment. Nice if you are definitely on a budget.
There's a Peachtree Audio DECCO 65 on audiogon for $450 that is likely going to be a lot better than the BasX integrated.
