I have a 5.5 with a pair of 185 monos. No problem with the pre but have an intermittant hum with one of the amps. it is probably a ground problem because it goes away as soon as the power switch is moved. it is't bad enough to fix and hasn't gotten worse over 3 yrs. sound...with dunlavy athenas. killer tight deep bass as long as it's on the recording, wonderful mids, open highs. overall i could't think of anything i would change except for adding a phono section to the preamp. the cost there has had me on the fence for a long time...don't listen to that many LPs these days. if the guy with the one with the phono section still has his for sale maybe we could work a three way deal if you are interested
