Thanks again - let me ask you one more question please. With the switch - I persume having both amp simulaenously on should not cause any problem (although that is not the intention). Could I keep the "analogue" connection from one amp (PMA1520) as primary while also maintain the digital optical connection from the other (AVRX4200)with the CD player ? Could this cause any issue ? Thanks

Well I just paid $ 50/- plus postage anyway - would you be able to explain the connectivities sir ?

Thank you 1 Would you be able explain to my question just posted - connectivity on the DSP-1 ? What does L= L-, R- R+ stand for ? Left and Right Channels I guess ? and what does "COMMON" represents ?

Thank you derrickdj1 - the most widely supported idea seems to be what you have proposed - unless I want both the amps to be "on" simultaenously and use the pre-out connectivity to connect both. Clearly thats not what I want. Amazon also have a unit called Niles ABS1 Black (FG00271) Speaker Level A-B Switcher - which automatically switches the amps and audio - I guess - but I would rather stick with manually operated one. On the Niles DSP-1 - that I have just ordered online, the connections - seems to follow a different codings - would you be able to explain how to go about this ? A picture is attached along. Thanks again guys - fantastci support - much appreciated!

Hello - help me out if you can please - I had a great AV Receiver Nakamichi AV10 - both my 5.1 and Stereo 2 Ch playback sounded very good. Yet - I went for a new AVR (well I have had the AV10 for 18 Years!) - Denon AVR X 4200. My fronts are Klipsch R28F. I was so disappointed with the flat 2 Ch performace for my audio collections - ended up buying Denon PMA1520AE as a dedicated 2 Ch amp - that would help me enjoy the CD's. (well at least I thought so...) The sales guy told me - I just would have to disconnect the jumpers behind the speakers - and connect one amp to one set of speaker binding post while the other amp to the other set of speaker binding post. Did that - but yet again - its just flat sound - as clearly by disconnecting the jumpers - only the tweeter is working with one amp. So - my request to you seniors here - is to guide me how to overcome the situation - after having spent loads of money on two amps and rather unnecessarily having discarded the loyal AV10. I need to have the PMA 1520AE for my audio cd's while use the AVR 4200 for the movies - but use it with one pair of R28F. (Please dont ask me to buy another pair of speakers - I do that - my better half would leave me !) I read a lot about bi-wiring and bi-amping - but cant figure out how that is a solution to this? But if it is the way forward - could one of you please explain step by step guide to make the connections please ? Please help. Thanks! God Bless!
