I've just sold my Nagra CD player, so the funds are gathering ready for the probable MCh SACD charge!

BTW I know DSD/Teresa is a big fan of Telarc SACDs, well I've just picked-up Hiromi - Spiral Mch SACD on Telarc. I'm still listening in 2ch for now, but I'm really impressed with it. Especially the piano sound. Anyone heard it in Mch or 2ch?

So, you've sold your Nagra......now, it's time for a name change +++++boy?????????

All the Heads up SACDs and Telarc MCH jazz releases, especially the Hiromi titles are wonderful, multi channel recordings.......also get the Philip Bailey disc (he was part of Earth, Wind and Fire ) Soul on Jazz and the Heads Up Sampler (Jazzin' Surround). All wonderful examples of surround at its best. Also, Al Di Meola's Flesh on Flesh and the Consequence of Chaos are models of surround envelopment.

Peruse the Amazon website and get them at bargain prices because they will not be repressed and are disappearing rapidly.

Thanks for the tip there rammie, must get them while I can.

BTW I still have 2 more Nagras! ;)

A while back I put my Nagra 2ch system away and tried-out a multi-channel system in my small listening room, here in Oxford, UK.

I used LS3/5As for the front pair and ProAc Tablette Reference 8 for the rears with no centre or sub available. These were fed from an Arcam AVR300 receiver and Cambridge Audio DVD99 universal player.

It sounded much better than I'd expected - afterall, it was just a lash-up of spare kit I had around the place.

Does anyone out there have a really satisfying, small-room multichannel system that they could tell us about? And does anyone wish to suggest a speaker package or combination for such a situation? It could be anything from entry level to high end...

I too have a relative small listening room (25 m2) and have set-up a B&W 804/805/HTMS3 speaker package with a base width of 2,3 m. I think this gave me a really satisfying results for listening my SACD's in MCH.

I am about to try out B & W CM 8 speakers for the front with PV1 sub-woofer , existing Kef XQ50 C centre Channel & existing B & W. MI for the rear. PV1 arrives tomorrow, the CM8's at the end of this month due to large demand.

A little bit of this and a little bit of that.....sounds like Minestrone soup to me!

What you really need, DB, is 3DHDTV...........stop being So stingy!

There REALLY are NO pockets in those caskets.....take it from one who sells them.

Or, do you plan to be cremated and have your ashes spread over the Meridian factory?

Nothing wrong with Minestrone my favourite soup. I have no interest in 3DHDTV at the present time, not a question of being so stingy! In fact I am thinking of changing my 1 year old Sharp LED TV for a Sony as the former's lack of proper HDMI control makes it incompatible with a Sony system. Being in the funeral casket business always in demand, no wonder you can afford Meridian's high priced products.

Well, after starting this thread just over two years ago I have finally at long last moved to a place where I can properly accommodate a multichannel SACD system! It's not a huge room but I'm able to accommodate all 5 speakers equidistant from the listening position - just like the ITU Standard suggests. With my preference for high-quality standmount speakers, the smallish room is not a problem - in fact, I like nearfield listening and my Harbeths certainly deliver when up-close.

The basic setup will be 5 standmount speakers each at a distance of 1.7m from the listening position. To some with cavernous lairs, this may sound really pokey and small, but it works very well for 2ch listening which I'm currently set up for. Although I only have the Front pair as of today, I've already measured out the angles and distances for the necessary Centre and Surround speakers according to the ITU Standard. The Fronts are each 30 degrees from the centre line making an equilateral triangle with me at the other point. The Rears are marked out to go at between 110-130 degrees from the centre line, but obviously I'll need to adjust this to taste when I actually set the speakers up.

I'll be using my Cambridge Audio 650BD universal player via HDMI into my Onkyo PR-SC886 AV pre/pro as source and control. My current Nagra MSA will power the Front Harbeth P3ESRs, but the other three channels are as yet undecided. I suppose this is where the difficulty starts...

It would be simplist in my mind to get hold of another 3 small Harbeth P3ESRs, but I'm aware that there is a commonly held view that the quality of the Surround speakers is less critical to the sound than the Fronts. With that in mind, perhaps I'm better to go for some modest speakers for the mean time? That leaves the Centre channel speaker. I'm aware that a 'phantom' speaker can work well, but as I am not restricted for space in front of me and there will be no TV in the way, I'd like to use a proper Centre speaker to preserve the original multichannel mix on the disc. I'm keen to use another P3ESR to maintain a seemless field across the frontal soundstage. It's just a shame to have to buy a pair of speakers and only use one of them...

So I can envisage buying another pair of Harbeths and using one for the Centre and buying some more modest speakers for the Rear channels. For amplification, I'm uncertain. I have considered using active speakers for the Rears to bypass the issue somewhat, then using Audyssey to blend it all in...Decisions, decisions. No wonder 2ch is more popular - there are so many questions with multichannel!

Nagraboy, I'd buy a matching pair of Harbeths and run it 4.0 (with phantom center) and worry about the center down the pike!

Sounds a very nice setup indeed. Many disagree with rammiepie about the importance of a decent center channel. We find that most high quality Mch SACDs have a discretely recorded center channel, and that they are best reproduced with a center channel.

I do not think with a digital prepro that equidistant setup is at all important. Distance correction in the DSP is effective and transparent. But, if you can accommodate an equidistant setup, why not do it. Note that with subwoofers, the measured distance often understates the true acoustic distance, due to delays in the sub's input xover network. So, the mike calibration in your prepro can be important in getting the sub distance parameter set correctly, because it measures true acoustic distance. I think a good sub can add tremendously to musical realism and does so seemlessly after Audyssey calibration.

Yes, I think Audyssey can be quite effective in taming differences between dissimilar speakers. Be sure to read the Audyssey setup guide linked to in the first post at this thread :

There is much information there not in the prepro manual about how to get optimum results.

Good luck.

Thanks Fitz, I tried using the supplied Audyssey mic when setting up the system for 2ch sound but it's unclear where or how to position the microphone when doing the tone sweep. Do you sit in the chair holding it at head height or put it on the seat and stand back? I've no idea and will read the link you posted.
