Amplifier Switch

[Kevian]

Guys,

I have an Onkyo 606 for HT job and Rotel RA06 for stereo listening. My house's renovation will be over in a couple of weeks or so. So, my equipment will be moving to "Music Hall" as I call it. For now, I'll be using Mordaunt Short Carnival range for fronts and center while DefTech Promon 800's will serve as L&R surrounds. This'll make a 5.0 setup.
My question:
As I have 2 amps and 1 pair of front speakers(which I'll upgrade in near future), do you audiophile guys think a product like this will be good enough in switching between amps? Will it be a compromise on music listening once I upgrade to better fronts? Do you have a better recommendation as my front and center speakers upgrade could be to Dali/B&W/Paradigm?

Russound AB-2.2

Hi Spiro,

Thanks for hopping in with a response. Thats a great DIY you did there. Did you feel any difference between direct wiring and via switch? This link gave me a fair idea of the schematic but the same guy says "resistance" would be an issue. Did you find any such thing in your DIY? This is the reason I'm looking out for retail ones which have no resistance. Thus, started this thread for better opinions from resident aadiafeels.

Cheers!!

i use the niles dps-1. that's a good solid product and does its job admirably - without losing the quality of sound from the source (i think/feel). but you can use only bare wire with it - no bananas, spade etc. biwiring also might not be easy (even if possible).

Yes,there is some issue after using switch for long as Electrical button is not the best choice.You can check this too-

@Nandac,
Thats great. Do you think this Switch has less if not no resistance? with what gear are you using this switch?

@Santhosh
Thanks for DIY link brother. Did you try anything similar for yourself as you have mentioned about it on the same thread@DIYable?

@Spiro
DNM one is kinda overkill for my requirement. Actually, I want to keep it as simple as possible which can be operated by layman persons like my father, mom, or anybody for that matter. 1 Deep press for movies, 1 half press for Music>> As simple as that. I hope you got my drift.

Cheers!!

speakers are sonus faber concertos. stereo amp is a rotel integrated. avr is a panasonic digital one. i didn't hear any specific/significant difference between hooking them directly to the amp Vs through the switch. i think the niles dps-1 is a good quality switch.

Thanks Nandac, I guess this might be my option. Are you from B'lore?

 

[nandac]

yea i am in bangalore. i bought it from smarthome.com. it took a while to get in and i got charged 30% customs duty for it.

I am unable to find Russound ab 2.2 in Bangalore or in India.

 

[Naturelover]

I suppose you would have checked out the dealer locator.

[santosh4]

Did that, but they dont have any idea.

 

[Naturelover]

Russound might be in the Whathifi show in Bangalore.

As an option you could consider getting one fabricated. Actually it is very easy to make. I had used one for some time a few years back but later shifted to separate setups for stereo and HT.
I am sure you should be able to get it made locally.
Check with spirovious how he got it done.

Re: Amplifier Switch (now without amp switch using AV preouts)

I am using this thread to raise a query on adding an integrated stereo amp to the existing AV setup.
My existing setup looks like this :-

For HT :
Sony BDP (HDMI)-->NAD T757-->PSB Image B5

For Music/stereo:
PC--->ODAC--->NAD T757 ---> PSB Image B5.

Now, I want to use the same speakers for both HT and stereo with an integrated stereo amp added. Here where my doubt is. NAD T757 has audio pre-outs for both front-left and front-right channels. The stereo amp that I am planning to add to the chain is NAIT 5Si. NAIT 5si has an audio input for the AV audio channels and an "AV bypass" option to by-pass its own volume control. With AV bypass switched on, AV receiver can control the volume.

My questions :-
Can I connect the AV receiver's audio pre-outs directly to the AV audio in on NAIT 5si ? The reason for asking this question is that the other audio inputs on NAIT 5si are of line level. The audio pre-out from the AVR is already a pre-amped one and not at the line level. So if the AV audio input on NAIT 5si is at the line level, then I cannot connect it with the AV pre-outs. It is not clear to me whether NAIT 5si's AV audio input can accept pre-amped signals. Please clarify.
