I've got a Denon 2307 7.1 amp at the moment, but a speaker upgrade is showing it up. I'm also getting back into my 2 channel music (part of the reason for the speaker upgrade). The way I see it I have a few upgrade choices - what do you think to each?

1. Upgrade to a better AV amp. I guess unless I spend a fortune, 2 channel music will still sound poor.
2. Get some power amps to drive the new speakers better, maybe bi-amp them (my Denon amp has pre-outs)
3. Buy a half decent 2 channel amp which will run the front speakers, while my Denon still decodes and powers the rear and centre channels. I think the denon allows this through the pre-outs.

Budget is around £1k, but can stretch if it's worth it.

Option 3 all the way.

I have a set up very similar; a Yamaha RXV640 doing all the decoding and powering front and surrounds with pre-out to a Cyrus 7 + PSX-R.

My CD and Squeezebox Duet plug directly into the Cyrus with blu ray and DVD into the Yamaha, obviously.

This way you'll get far better stereo performance, as you rightly say, a AV amp to compare to a decent stereo will cost a fortune.

The problem with Option 3 is volume control. The Denon Pre-Out will probably require the stereo amp to be set to a much higher volume level than if it were controlling itself and if you forget to lower the volume before using it in stereo you could damage your speakers. How about buying a preamp/power amp combination for stereo. Then you could run both the Denon front L & R pre-outputs and the stereo preamp's outputs into a switchbox and into the power amp. That's what I do.

I dodn't know what your budget is for the stereo amp, but Audiolab pre-power combinations can be had at around £1k and Cyrus from just over £2k.

+1

You really want to upgrade the front 3 channels at once to keep a uniform sound field. And if you are going to do that then you may as well go for a 5 channel and do the whole lot!
The Rotel is will provide a very worthwhile upgrade and is under budget http://www.hifigear.co.uk/site/scripts/product_bro...

What speakers are you using?

I think he meant power amp rather than a separate integrated (?)

No, both were options. I used to run an arcam syatem and when I stared getting into AV I found an amp which let me use the stereo to power 2 channels and the amp dealt with the other 3.1. This let me use the arcam amp normally for CDs with the front AV speakers.

Zod - where did you get the switchbox? My google skills are poor today.

Some stereo amps such as Arcam A32 or A36 have an 'AV' button so that you can feed your AV preouts into the auxiliary input and the gain is fixed (you still need to set up the levels using your AV amp's controls), so the stereo amp acts just like a power amp on that input. For the other inputs such as CD or whatever the volume control works as normal on the stereo amp completely taking the AV amp out of the equation for stereo music (it won't even need to be turned on if listening to 2 channel music).

I was about to go that route myself, but happened to get a response to a wanted ad for an Arcam AV9 processor which does a very good job with 2 channel anyway, otherwise an A32 or A36 was on the cards for me...

I'll have to look it up again. Mine was tough to find as I needed an XLR one. RCA ones are much easier to find.

Brilliant - thanks.

Before I start bothering dealers for trials of 2 channel amps, are there any AV amps out there which are also musical? Marantz do them now, as do Arcam? I need the picture switching functionality.

How about a NAD?

There are several, but despite having a high end Arcam processor, I still find it cannot match my Cyrus DAC-XP for stereo.

That's interesting, which processor did/do you have (I've bought a used AV9 myself and I'm very impressed with it's stereo abilities, but that is coming from a Denon 2808 or a NADC350)?

Next stage is to add a Lyngdorf TDAI2200/SDA2175/DP-1/BW-1 Combination...

I always followed this purist approach and ran separate 2 and 5ch systems with a bi-amped Arcam Alpha 8/8p into a pair of Mission 753s for hi-fi.

Looking for an upgrade however I tried the Denon 3808 and was blown away with the Stereo performance. You can bi-amp the fronts if you have 5:1 (rather than 7:1) giving so much more power than the Arcams for a vastly more authoritative sound. I was amazed as I'd always believed that a receiver would never be able to compete. Needless to say the cinema sound is awesome too.

I paid a little over £1k for the amp - may give another option to think about.

Nope. Not there on my phone. Will check PC. frown

Something tells me Lyndorf would open a whole new world of insane spending.

Arcam AV888. It is very, very good, but in stereo, it cannot match the DAC XP. It is not really surprising, given that the DAC XP is a top quality dedicated digital dual mono pre-amp.

Bugger, will send again.

Well, you're always welcome to a no obligation demonstration...

I ended up buying an Onkyo AV amp, used. It was cheap enough to be able to be moved to the study when we move and I get my cinema room. I must say, it doesnt seem a great leap from the Denon at the moment, although I imagine a settings tweak will help there.

Did you buy the Onkyo from a guy on AV Forums?
I certainly did. He kindly dropped the books round yesterday but I rudely haven't thanked him yet wink

I used the Audyssey set up last night and it is many, many times better now!
