I purchased the PA-7000 preamp to expand the number of inputs and outputs on my component HiFi system. I am using the tuner input with a Denon TU1500RD Tuner, the phono input with a circa 1980 Denon Turntable, the tape input with a circa 1970 JVC Cassette Player/Recorder and the AUX input with a Direct-TV DVR. The PA-7000s unbalanced output (ordered balanced cables for future upgrade) drives a PreSonus Central Station Controller which then drives a Furman SP20AB Amp and a set of custom-upgraded, Infinity Speakers. I listened to the PA-7000 with Beyerdynamic DT770 headphones as well as speakers, at maximum volume, and the noise and hum levels are barely audible. The phono preamp sound quality is excellent and my wife could hardly believe it when I played some records, how clean and natural they sounded. The only minor audio performance flaw I noticed is some crosstalk between the adjacent inputs with the volume set to maximum. This is not a major issue for me, as only one of the input devices would typically be turned on at a time. The tone, balance, volume controls and other front panel buttons work as advertised and all the controls are smooth and crackle free. The chassis finish is nicely done but the mid-point detents on the control knobs do not line up with the markings on the chassis. I did not test the microphone input but overall, for the price, the performance of the PA-7000 exceeded my expectations.

this preamp uses standard rca inputs and 2 pairs of rca outputs.(also has a pair of xlr outputs which i did not try.)the headphone output is at least adequate,but this preamp really shines driving my "total airhead" solid state headphone amp and also my new hong-kong 6bq5 tube amp used as headphone amp off 8-ohm terminated speaker leads.the tone controlls cannot be bypassed, but i was surprised at how useful they were.my sony mdr-v600 -phones really can use the bass boost the gemini can provide.preamp has no detectible hum or rfi issues.outstanding value.
