Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Trifield (again)

Hi guys! Have been away for some time so didn't get to follow what you've been discussing over the last month.

I have a voice recording of the entire HH2 Q&A session and will have a listen to it and report exactly what she said, if you want. That's assuming the recording of the particular point is of good enough quality - heard most of it and it was.

Was also going to take photo of the diagram on Trifield, but decided that perhaps they didn't want us to do that. Shame.

Will get back to you.

Philip,
That would be really helpful. A little MP3 of it too would be nice

Ronnie, I agree that depth is the single biggest effect. The 'snap' seems to describe it well when you get it.

Width always made changes to the apparent amount of content used in the L & R vs C.....at least as I recall.

Double deaf listening...love it !!!

PS...I didn't think they were definitive/100% about it working. The word 'should' was in there somewhere based on the thought that they hadn't changed anything.
Rhonda said the code appeared to be working properly also though but I don't know if that was based on a definitive check.

We had a thread about a year ago - I swear that Trifield Width used to have a profound impact (mayhave been when I had my M100's and not my DSP8000s. Now it has no audible effect. I used to love to play with it on really spacious recordings. I'd love to have M fix it, though they'd have to fix my 568.2 (or perhaps my 8000s?

As Frank has mentioned, Meridian undertook from the January (or was it June ) CES Q&A to check into the code behind Trifield based on the feedback from here

However, as Nick mentioned above, I also got the distinct impression that while they had considered it, it had not exactly been an exhaustive study to determine if there had been changes

We all suffer from Selective Amnesia from time to time, but I certainly think the consensus here is that the Width setting in Trifield, does not do what it did a few years ago and with DSP speakers (not just Analog)

Personally, I cannot say that Trifield performance suffers as a result, as I always seemed to prefer Meridian's default Width setting anyway. Anything else seemed to alter the sound in a negative way (to my ears of course)

Confirmation from Meridian would be useful, no doubt

I haven't upgraded to big DSP speakers and my old 568 and current G68 have both been in use with my current ATC actives.

The 568.1 definitely had a sweetspot for Trifield at Width = 1.3. I reproduced this setup when I changed to the G68 and I spent a bit of time fiddling around changing the width (noticeable!) and confirmed that 1.3 was preferable.

Over the years I have updated my firmware as new versions were released but never tested the width setting again until this matter was raised earlier this year. I can confirm that, as stated above, it now does nothing (that I can hear).

Yes, depth is important for integration of the centre but the width setting is also one of those which "snaps" sound images into the correct focus.

I'm using upgraded D5k's across the front and a G68J. Neither my wife, daughter or I can hear any difference playing with Trifield width. We tried an iPod using an Apple dock as an analogue source first. I picked a couple of songs that had decent seperation and--no change. Then we tried a redbook CD with the Oppo again without any change. I really don't think anything is happening.

With my set up mono in, is centre only as it should be

If there is difference it shows in L and R

Sum and Difference

Mono = 0 Width

OK 565 with analog set up.
I Just tried width and found it on the Trifield setting but not on my personal pre-sets.
I Listend to Ken bruce BBC Radio 2.

On the studio Chat, the width seemed to make no noticable differance.
Then Jamie Cullens latest CD Came on. The Piano Rhythm does move in and out with width. I prefer it at 1.0 Max and cant think why I would want to change that.
Depth and centre level are far more impactfull.

My advice, set it to max and enjoy the system.

Cheers, Chris

I confirm that my 565 only allows width setting up to 1.0 while Malcolm above refers to 1.3. Seem to remember my 568.2mm allows up to 1.5 so something has changed.

I'll try my set-up with another source, satellite used before was just convenient. Maybe a music source will be more revealing?

I'm not being negative about the 565 but it is an old system now and it seems that the Trifield width issue relates to a firmware update that was done to the G series (maybe 568.2, not sure about 8XX) which seems to have changed something.

True Malcolm, but at least it confirms that folks *are* seeing differences with older versions of Trifield.

And somone did ask for an analog 565 set up opinion.
