…Am I likely to want the LM4562s back? I dont think so. I’m hoping that as the components bed in over the next few days and I get used to the sound I get further improvements. Is this money well spent – well as I said before this is not a bang for buck upgrade but a final push on an already great sounding card. I have no regrets.
