I was using my MSB DAC direct to the amp without a separate preamp. My local dealer loaned me an ARC LS28SE to try. It was only marginally better than the DAC direct, not even close to worth the money for it. But I could hear some potential. So I put in an ARC REF6. That was a substantial improvement over the LS28SE and it is happily in my system. Stretch your budget a little and go for the REF6 over the LS28SE. They can be had on occasion for $7K or so.
Audio Research Pre-Amp advice
Hi, what would be a good used Audio Research pre-amp that has a remote, that is overall very musical. My budget is under 6K? I really don't want any Ref. pre's because too many tubes. Also something not too old, I do not want to have to bring in for service. I welcome and appreciate any advice. Thank you!
