AV2 preamp section

In theory - yes.

Both preamplifier sections mentioned are better than that in the AV2 and, for dedicated analogue 2 channel should product superior results.

If you were planning to part exchange the NAP 200 for one of the integrated amplifiers - I would still expect an improvement. Big swings and small roundabouts?

Sensibly (given that both the SuperNait and NaitXS have (redundant in this instance?) power amplifier sections - one would add the option of adding a NAC 202 - connected to the NAP 200.

The front channel output of the AV2 (for multichannel) would be run through the AV input of the 202 (in Unity Gain mode) and then to the NAP 200 for the front speakers. Analogue output from the DVD5 would run direct to the CD input of the NAC 202.

This is, with different models, how I run my system.

Adam,

thanks for your reply.
Actually, I was considering changing the 200 with one of the integrates because I would gain a preamp section and would use - both amps have this facility - the power section to do the job of the 200. A 202 would be perhaps a bit too much for me to just optimize the analogue output of the DVD5.

I use the DVD5 as all-purpose player, and have the multichannel board fitted, with the versatile inputs of the AV2 configured as combined. So, I was wondering whether I could split a NaitXS or a Supernait and feed the proper Snaic4 from the AV2 to its power section instead of the 200's. What's more, I believe both integrates can be upgraded with Hi-Cap.

Regards

Reading the manual I could check the connections on the rear of the AV2. If I take the L+R (front) output from the DIN 3 of the AV2 with the reversed cable (which I have, BTW), and feed the Unity Gain of a pre or the preamp section of a (splitted) Integrated, then take the proper SNAIC4 from the AV2 to the power section of the (splitted) Integrated, will it still main any significant improvement in the treatmnet of the front (l+r) signal?

Yes, it takes me three questions to voice a simple issue - but I suffer springtime. Sorry.

Feed the FRONT L & R signals from the AV2 into the AV socket on the integrated and USE Unity Gain for that socket.

This effectively does exactly what you suggest above (gives direct input to the power amplifier section of the integrated) while ALSO allowing the 2 channel analogue signal from the DVD5 to pass through the integrated's preamplifier section and power amplifier for the best 2 channel reproduction of CDs.

Your suggestion is
1: unnecessarily complicated and
2: would disconnect the integrated's preamplifier section from its power amplifier - a bit silly.

This way - you could later add a HiCap (which powers the preamplifier section) to the benefit of both 2 channel AND the front L&R channels of surround sound.

Thanks. It was effectively complicated. And I still mistype some words, which probably makes my suggestions even more silly.

Hay fever isn't fun.

My IQ drops - just off to watch TV.

I thought you said you hadn't any..
My wife's out for her choir conducting tonight, so I'll rent Saw V or something. My IQ drops.
Have a nice evening.

Adam,

I may sound silly, but -
having thought about it (and knowing you know what you say): if I do what you suggest, how does the front signals from the AV2 go into the Unity Gain input of an integrated BOTH reaching the power section directly AND benefiting from the preamp section?

Sorry for the silly question, but I'm puzzled...

M.

You plug you 2ch audio source into the pre and multi channel into the av2

Occean,

thanks for your suggestion but I fear it's not what I was asking. Adam has already suggested a very detailed connection setup for the use of an integrated instead of a Nap200; what I am asking myself (Adam, actually) is, if I feed the front channels (of the multichannel analogue signal I am carrying from the DVD5 to the AV2) from the AV2 out to the Unity Gain AV socket of the integrated thus feeding the signal directly to the power section of the integrated (and adjusting the loudness from the AV2 - understood it, so far), how come - just out of curiosity - this also makes the same signal benefit from the preamp section of the integrated?
My question being based on my assumption that if you feed a signal direct to the power amp you more or less bypass the preamp and just adjust the volume.
Now I know that >more or less< is just the point where Adam will do bits of me...

I believe Adam is suggesting a connection from the DVD5 to the AV2 (for multi channel which is then fed to the 202 via the unity gain input) AND a 2ch connection from the DVD5 to NAC202 hence benefiting from the pre and power sections

but we'll wait to see what he says....

Hi,

you maybe right, but I have written in my first post (up) that the DVD5 is connected to the AV2 both via DC1 coax (film and concert DVDs) and via the analogue, combined outputs 1 and 2 via special interconnects (I have the multichannel board). So I thought I can't use any other connection, and the only possible front, L+R output is the one I take from the socket of the AV2 to feed the Unity Gain of the pre, or integrated, and throu which only left and right channels - of stereo CDs, or front of DVD-As - pass. So any stereo analogue replay, such as of a CD, is done via this multichannel connection. And I believed that these two LR channels were taken from tha AV2 to the pre, o preamp section of the integrated. But since the Unity Gain input I'd use, goes directly to the power section, I was - somewhat bravely against Adam's suggestions... - wondering if this would have made these stereo channels pass throu - and benefit from - any preamp stage.

I'm beginning to feel numb... I'll wait for a further Meredith word, if any comes. Cheers!

Adam,

as told in the HiFi corner, I am auditioning a Nac 112 (2001, how I love those RCA-less rear panels), and you were perfectly right, of course.

Cheers.
