Hi,bought a yammy a2070 7.1 dsp for £40 after reading the reviews about its build quality and its 2 channels stereo performance when you disable the dsp effects and run it in pure stereo mode,the build is amazing,has a huge 18lbs el tranformer,huge nichion caps,stereo performance is really really good,huge amounts of bass,the build quality is better than my yamaha rx1060,what i want to know is ive conected my yammy rx1060 pre outs to the rca inputs on the 2070,im getting much better stereo quality than jst using the x1060,do the pre outs on the 1060 do all the decoding of dolby digital and the send it to the 2070 ,or am i always getting jst pure stereo,if i can use the 1060 preouts for all the decoding dolbydigital/atmos and use the better quality amps in the 2070 then this would be a very cheap upgrade,my 1060 says its doing dolby digital decoding jst dont if by the time it gets to 2070 its being converted to stereo ,can i do this,if not il use the a2070 for 2 channel in my room

Hi ,thx for letting me know i havent set it up right,sorry about the spelling still cant get used to my tablets keyboard,i had the left and right rca going from the 1060 to the cd input on the 2070,didnt realize the 2070 pre outs were pre in ,i watched deadpool like this last night and it wis brillant,to my ears it sounded a hell of lot cleaner,bigger and more dynamic,switched bck to 1060 to compare and it wasnt the same,and that was only stereo Dam..wonder what it will sound like when ive got connnected the right way,so i need to connect to pre in,what about the rears,its a 7.1?can i connect those aswell,also as the 2070 dosent have optical in,what happens if i connect my dac with rca into the 2070,am i using the dac inside the 2070 or am i using the external dac chip,i know usally when connecting a dac with rca you are useing its built in chip,and with optical id be bypassing the external dac and use the dac in the 2070,if yamaha built it like that then that would mean if i used a cheap dvd player into the 2070 with rca and svideo id be useing dac in the dvd player,i wouldnt want to do that,and the amp was up in the loft all boxed for 10 years,is in mint condition

When i connect rca from the 1060 to main in on the 2070 which input selecter do i use

Connected it the way you said, 1060 into pre in on the 2070,but the volume control,dsp effects,and the bass, tone control are not working this way on the 2070,im getting sound but volume knob does nothing when i turn it,have to control these with the 1060,is that normal,been useing the pre in ,not sure i like it,ive lost all the bass,what diffrence does it make if i jst use the cd rca input and switch off the dsp effects for stereo mode
