The 1L will deliver a good amount of watts, but the transformer is somewhat light at only 450VA. The Parasound integrated looks to have a much larger transformer, but not as much capacitance. It could be a number of reasons why the Emotiva 1L could not supply the current.
The Emotiva amps stock are quite bright and harsh, although I do not have experience with Gen 3 and their new switching power supply (also with no fuse). If you absolutely need to have that much power and have a limited budget, the Emotiva amps can sound nice when you convert the fuses to Isoclean or Furutech (or a combination of).
