dr.strangelove i only found a brochure with colour photos this year and got it on ebay from a seller in north ireland, it talks about surround it as matrix 2 and 4 ,it simulates quadrophony with another pair of speakers wich i did a long time ago with some celestion ditton series wich seemed to give a boost to the sound level it as a incredible treble sound and level as the bass and a incredible strong loudness wich i use on all the time, still using it with the original cartridge and stylus ,it does have a clean and perfect sound ,even for a few monthes tried it on a late 70´s pl-560 wich makes part of a system i bought later from pioneer being this good i purchase in late 70´s another pioneer system, the pl-560 ,the stereo receiver sx-1980 ,and a hpm speakers wich i have to confirm because i thought they were hpm-1500, but in the internet i´ve found similar just having as reference hpm-150, i have bought through the years other components from diferent brands but it seems as newer they get the worst built they are(this to do not talk about the dynamic of the sound, i´ve bought in the 90´s a two blocks mono amplifier and a pioneer pre-amplifier ,the selector since then it gave problems two times and with a rec selector even worse ,i was recording a cassette and sometimes one side just stoped making sound and i was looking in the deck if it was just the rca cable who wasn´t making always contact, than already thinking about opening the deck when i move the rec selector to record from a diferent source and it started again giving sound so the rec selector was also not working properly , this to say that the es-2000 system stereo reciver as one selector that never make any noise or just be coming sound from one channel ,the treble and bass knob i already cleaned it twice since it was bought in 73 but are working perfect since i cleaned it in 2007, it´s a good system and not a entrance system ,i´ve seen others like with the minimum function ,even with only tone and not treble or bass ,it´s in a early´s 70´s catalog ,i´ve met a girl from a litle village in the midle of nothing who in her bedroom she had since she was 14 this system more simpler but the quality of the integrated turntable was good , i still use a pc-30 cartridge with a pn-30 stylus and sounds perfect, some even sale the pn30/50 wich the plastic of the needle is a few milimeters longer but i´ve found in a litle village a guy who had a electronics litle store and i went to see the store closed 20 years ago and found 2 original pioneer pn-30 and also a ct-520 deck with a lot of plastic wich i bought amongst other curiosity´s he had closed in the store and it records with a very good sound compared to other 90´s decks from more popular brands
