Finally cracked into the 100 reputation points barrier. (Self proclaimed unashamed propaganda )



That too after posting only 196 posts in hifivision.

My Rep Ratio : 100/196 = 0.510

Has anyone have a better rep ratio than me? Just for interest.

This means my every other post received a rep point.

Man i do not know how a noob like me get so much rep points.

I want to thank every audiophile & learned members of hifivision for giving me this opportunity and to be a part of this wonderful group of people and let me grow.

Warm Regards
rishiguru

Before marriage, no one introduced me to this hobby. Anyway I neither had money nor the wife or time. Now I have money &some time but wife also.
You are lucky to have money,time but not the wife.

Re: Yamaha DSP-A2070

Hi Rishiguru,

I have a Yamaha DSP A1 that I got in 1998 in the US. I used it for 4-5 years, then moved to India. Its been sitting in a box all this time and just now I have taken it out and tested (After I got a good voltage converter!!) to see if its still working. It is!

I hope to get the HT setup done in another month's time and back to enjoying the Yamaha experience. It looks almost exactly like your 2070.

Nice to see someone here who has a Yamaha DSP series and enjoying it.

regards,
Dovin

Congratulatios jaudere for being fortunate enough of having a wife who understands your needs regarding music & Audiophilia!!!!

My elder sister can hardly differentiate the sound quality between Logitech Z-2300 & my mighty Yamaha DSP-A2070

She thinks Z-2300 is cute while DSP-A2070 & Sony bookshelves are black ugly boxes. According to her these systems should be very small so that they do not rob the decency of the room.

Man you are lucky.

Anyway I feel good to be back at hifivision after nearly two weeks of hard work for official reasons. I missed a lot.

Thanks dovin for your appreciation. The DSP-A1 is undeniably one of the best amps of Yamaha. I think A1 was released after A3090. This DSP range just got fatter with time having more & more features cramped in.

Regarding me, well I am just a regular bloke who is trying to understand what true sound quality really means. And I know I have lot to learn.

These couplers are for using these amp as a pre or power amp. These couplers connect the inbuilt 7 channel pre amplifier with the inbuilt 7 channel power amplifiers.

So by talking out the couplers one can:

1) Use a discrete 7 channel pre amp with the DSP-A2070 used as a 7 channel power amp.

2) Use the inbuilt 7 channel pre amp to power any discrete 7 channel power amp.

The dsp series are very well known for their good phono stage. And yes upto 2 subwoofers are supported by DSP-A2070 pre amp.

Tend to disagree with you here ........

In a still atmosphere, where there is no air movement, whenever there is a heat source (in your case, the heat sinks and few transistors) natural air convection currents set in. 'Heat transfer' makes the heat source transmit the heat to the immediate surrounding air, which gets hot and naturally rise above. The ampflier is so designed that the air vents are placed on top of it, whose role is to throw out the 'lighter' hot air from the amplifier top, thus creating a negative draft within the amplifier, which inturn invites the surrounding ambient cooler air to enter the equipment from whatever 'other' inlet ports given. You say, such ports are there on the bottom of the amp .... right? It is for this reason your amp used to get hot on the top .... as all amps do. But, thats how is has been designed !

What you have now done is to force outside cool air inside. You have made this into a 'forced' blow-thru unit ..... which might prove counter-productive. Why so, since many components which may not be attuned to ever get heated would now continuously get a stream of warm ... maybe, hot forced air .... might be detrimental in the long run.

What I would suggest, is that you reverse the fans and make it into a draw-thru operation. In other words, pull the hot air from the unit top. This would create a strong negative draft inside the unit ..... which would bring in outside cool air continuously .... and keep the unit in its original format. You would now find a steady stream .... sorry, blast of hot air blow from your amp top. Coooool ... thats how the Japos have designed it.

Obviously, the Calcutta heat (air) would also get carried in and end up getting hotter than usual blast from the top outlet..... which would make matters bad in a non-airconditioned listening room ...

"superhot" info!!

Thanks for saving rishiguru from wrong blowjob!

Re: Yamaha DSP-A2070

Apparently there are some folks who post here that appreciate the yamaha dsp a2070 amplifier and I would value their input as to the current monetary value of a good yamaha sytem that I have located. I have read the posts concerning this amp by rishiguru and appreciate greatly the comments and specifications.

by the by: Since the value of a good 'wife' has recently been discussed I'll have to admit that Robin gave me a pair of 1982 vintage Klipsch LaScalla speaker for my last birthday after a late night confession (later forgotten) that I had drooled over the speakers since I graduated from high school. ... I know the worth of that... priceless

and in fact that's why I need a good amplifier because I've got a good wife heheh

ssooooo.... I'm not calling my self an audiophile but I have a pair of La Scala's and I like to play them loud... I appreciate what they sound like and I'm not looking for sound processing but sound amplification. I only have some Bose 201s and some advent a200s otherwise but the klipsch are in the shop and need to rock. and here's the skinny:

I've located a system consisting of three components what would you give for them if they looked new with remotes and user manuals etc... like they sat in a second home and didn't get use much at all.

yamaha dsp a2070 processor/ amplifier
yamaha dx2 amplifier
tx480 reciever

it seems as though I would have two amplifiers either of which would work for my two speaker system although I know the mx2 would require a pre amp to work solo and the signal processor of the a2070 is dated but (not required specifically for a two speaker system) the reciever is of no value to me at all but oh... i'm drooling over what I know about the amps....

advise me please
