Calibration Discussion.

[Deleted member 2457]

What do you think about image retention with being off the normal settings?

If anything, calibration will reduce the chances of IR.

:cheers:

I thought if you change from normal settings you disable the pixel orbitor though? That can't be good for image retention?

To gel - I'm glad you mentioned image retention with the ZT i get image burn with the oppo home screen for a few minutes every time I turn it on ?

To ellisdj - yes maybe the apple airplay thing can be sacrificed .it was a bit of a deal breaker but I'm getting into headphones a lot now ,yes the anthems have been getting good reviews,I have my heart set on the monitor audio apex 7.1 tho I will ask nearer the time what you guys think will be the best partner for it.

as for the demos I'm not sure what to do the now closed home cinema centre and James morrow demo rooms were massive compared to my home cinema room I just feel I will get a false sense of sound if you know what I mean.

As for the audio calibration with pretty much a perfect square room with 3 stone walls with the tv 10 ft in front of me will an audio calibration be needed or is there a lot I'm not thinking about?

This is what I am worried about, image burn is not good! And I do think it happens on these plasmas. That really shouldn't do that with the Oppo logo! What are you going to do?

 

[Deleted member 2457]

You see I don't think your pixel orbitor is on is it?

 

[bigboss]

Its worth considering the new anthems - personally i wouldnt touch anything less than the 710 - its a mistake in my eyes to scrimp and buy the 510! A big mistake!!

Come on now, don't be melodramatic.

You really should demo & compare the receivers before dishing out advice. My demo comparison is nothing like how you describe, neither are the reviews of the 510.

Pixel orbitor is switched on my isf day and night settings and i have no IR

Is there a way of checking? Or did your calibrator let you know it would still be on? Cheers.

Gel, I don't know about the settings for Panasonic plasmas, but on all four of my plasma sets it's easy to get to the Orbiter option from the Picture menu. As bigboss said, if anything calibration will reduce the chance of image retention because a calibrated television is probably less bright (but more correct, and with greater dynamic range - the difference between the brightest and the darkest parts of the picture) than an uncalibrated television.

I just found the orbiter!

One last thing with calibration is night and day settings, I guess you have to switch between the two? How does that work? I mean do you go into the settings and select it each time? And do you have to do that anyway? :cheers:

To BB - The inportance of a linear power supply can not be underestimated - smps power supplies are not anywhere near as good.

Look at all top quality high fi or av - the vast majority has a linear supply. This is for a reason.

Meridian have just all updated their processors to all have linear power supplies. It matters for digital - naim have known and been sellibg these products for years so has cyrus and many other hifi firms.

For the small difference in cost the 710 will be a much better buy no doubt in my mind.

I would only buy the 710 i wouldnt touch the 510.

Why do you think its in there in the first place???

 

[Series1boy]

Screen options and it's in there

Gel you use pro 1 and pro 2 settings simple.

I dont ever change mine. It looks better in a darker room but the VT does this regardless

 

[Series1boy]

Yes Gel you have to go in and change from day and night. I've setup a sequence on my harmony remote, so all I have yo do is press isf day or night button and it changes it automatically..

:cheers:

When you put the orbiter on do you have to keep selecting each time? Or does it stay on? And on the pro settings is it automatically on already?

Did you take a course in calibration? Can you buy the equipment and self teach?

Check latest Home Cinema Choice magazine. Steve Withers talks about calibration. His equipment is worth £10000.

Aha! So you must have got hold of one of the few remaining copies of HCC issue 232 on newsagents' and shop shelves bigboss, because in the other thread that I started "Stve Withers talks about calibration" I carefully didn't mention exactly how many thousands of pounds his equipment was worth, mainly because I didn't want the poor man to get mugged by a rogue "customer"!

By the way, my subscription copy of issue 233 arrived yesterday.

 

[Son_of_SJ]

i hear what your saying gel but what you think is a good picture and what is the proper picture settings should be might be totally different .i don't doubt your VT has an excellent picture but after all you have spent on your home cinema set up the calibration is the last step

i can understand people with a budget tv not taking the leap as the calibration might be half the price of the tv but £3800'on my ZT then £200 for the calibration was an easy decision for me.

im sure Son_of_SJ will agree he thought he had an excellent picture then when mr withers took a pre calibration report his blue was off the chart ,little things like this make the calibration worthwhile.

Correct, for the Samsung PS64D8000. The other three plasmas were less far out, but still well out. And I had thought the other three plasmas had an excellent picture also, pre-calibration.

Thanks for the heads up Ellis, i will give that a go on my next calibration run. But i have to say for now skin tone looks pretty good on my ST.

In answer to some of the other guys,

Steve is one of the best callibrators we have and i would love to own the sort of calibration equipment these guys have, but the i1 Display Pro is one hell of a good meter.

What size windows are you using to calibrate?

 

[ellisdj]

I have read you want to use the same patterns for the whole cal. That's what I do

i was also recommended to use 4%apl windows - after using these I got a much better cal than standard 10% windows

the results were just as good obviously but the rsultant image is much better - never want to touch it again good

you can get these windows on a free disc called Masciators - google it and you will find the thread on it.

I found on the ST that when taking Gamma readings usining 4% the auto ABL would kick in giving wild results but yes 4% for WB etc on the ST is good.

I am using the AVSHD disc for my readings.

Using the APL( small ) windows in Chromapure for White Balance etc and normal for Gamma.

 

[ellisdj]

That's why the Masciator disc was recommended its much newer than AVS and designed with newer Panny plasmas in mind.

i was recommended this for the VT - maybe the ST is different but it's worth getting the masciators disc and trying 4% APL and see how it works.

i also found 30ftl or 60 contrast colour -2 brightness is + 8 on mine - this is a sweet spot for this screen, with patience I got a 0.5 avg DE grayscale and damn near perfect flat gamma I mean damn near.

i also found when you take a reading with the menu on the screen it reads different so you have to shut the menu down when taking readings

otherwise it's off

27% cost difference may be small to you, but may not be to others. Not long ago, when you had the Pioneer AV receiver, you argued that was the best on the market, and refused to believe my demo experience until you changed your setup. Does Pioneer have a linear supply?

Also, it depends on the speakers whether they're capable of bringing out the difference in the receivers. It is not wise to make a blanket statement about receiver choice irrespective of the speakers.

Forget what's on paper, I would recommend you demo the 510 & 710 back to back first.

I'm not denying that linear power supply may be superior, but your comments were pretty strong.

 

[ellisdj]

At the time of praising the pioneer lx83 it was the best receiver I had heard and it is still better than what I said at the time yamaha z7 et al. It's still a very good amp

i have since heard proper hifi in the right environment and it was eye opening.

following this I have learnt more in the last 6 months than previous 6 years about the importance of power supplies.

i personally would not buy the 510 over the 710 having the linear in it makes it appealing. Having an smps doesn't. Having a proper linear power supply is expensive but it's worth it. People need to know the importance hopefully I am helping people.

if they can't afford it and can only afford the 510 there's nothing I can do about that - but that doesn't make the 710 not worth the extra.

if it doesn't make an improvement anthem have done something very wrong, but I already know what it's impact will be.

if you want to know what a linear does read up on Paul hynes he makes some of the best linears available.

Linear supplies are low noise - this means much lower jitter compared to smps even low noise / ripple supplies. Linear supplies give a much richer more organised and composed presentation and that just for a digital transport
