I'll be using the Realiser purely as a Realiser only; I will be using a separate DAC (via Realiser's optical out) and headphone amp.

 

People believe and hear all sorts of things, but you would be using a purely digital path, inputting digital HDMI and outputting digital (especially optical which removes any electrical connection to the upstream). What would you think would improve? Maybe if you were using the analog outputs a theoretical difference could be found.

 

Some purely digital devices, such as the SOtM dX-USB HD (a USB transceiver), actually benefit from a better power supply, such as its matching mBPS-d2s. I know because I've owned both and did a fair comparison: the dX-USB HD with and without the mBPS-d2s. Are you saying that there is "theoretically" no difference in using a better power supply, if there is no analog signal path?

 

Spec-wise, the mBPS-d2s would also be compatible with the Smyth Realiser.

So it's really a battery pack? Maybe the other psu polluted your power grid. :D

 

There's no end to upgrades, but with Realiser everytime you do a HPEQ or PRIR measurement, they will never sound 100% identical anyway. If you believe a new realiser PSU will make those measurements and results sound "even more realistic", go ahead try and report back. I'm truly a sceptic for this particular scenario though.

Cool, I only now realized that I don't even need to modify some 4-pin plugs to use the Realiser mics for headphone graphs. MENU-CAL activates sending the live signal through analog and optical, that's all there is to it..

 

Here's a sample of HD800 using my ear and REW..

Hi Hekeli,

 

Thanks for the great info! Just wondering, are using your own custom HPEQ and PRIR for it? I'm asking because I thought it may be interesting to use this to compare amps/headphone combos... but wouldn't the custom EQs override most of the differences?

I believe the Realiser in the "MENU-CAL" mode just sends the audio from the mics (and mic preamp and amp) out to the Realiser outputs directly.

 

So, yes, this is an interesting way to measure headphones since you are using in ear mics to get the measurements as opposed to sponge or some other headphone coupler. Might be similar to using a dummy head for headphone measurements.

Thanks for the quick reply darin - your contribution to this thread cannot be understated.

 

I'll try to find some time to test this out this coming weekend, too.

It's just a nice bonus to use mics like this for easy measurements. No coupler building, atleast bass should be pretty accurate. I'm only looking to compare different headphones on my head (I doubt amps/dacs would show much difference), missing ear canal resonances doesn't matter to me.

 

Realiser mics should be pretty identical and atleast HD800 is one of the most stable measurements around, would be curious to see other people do it.

 

Using my old M-Audio Transit as optical in/out which is handy and clean, but should not matter much what you use.

post #2588 of 2713

Been toying around with it now quite a bit. Room EQ Wizard can do pretty much everything you need and easily. Everything seems to be nicely accurate and repeatable, I average atleast 3 measurements (256k fft averaged 4 times), re-adjusting mic and cup each time.

 

Did some testing with Superluxes, great help comparing pads and even isolation..

 

If anyone needs help setting up, feel free to PM.. continuing here is probably going a bit OT..

Hi,

 

Tonight I've tried the dual users mode, and I had some kind of an issue.

 

 

Second user mode means I have to output signal through the 3-4 Line Out.

I'm using a Musical Fidelity M1HPA and Beyer DT770 (96db/80Ohms).

 

Once everything is plugged, I engage the dual mode setting, and so 2 Presets are played simultaneously, the fourth for the second user, and any other preset chosen 1, 2 or 3, for the first user.

 

 

The problem is that the output level on the amplifier is way too low.

At full power, the sound is not even too high.

 

I've plugged my iphone to the Line In of the Amp...and there is a much higher sound level.

 

 

Any idea where that problem may comes from ?

 

 

 

Guillaume

post #2590 of 2713

I reply to myself...shame on me.

 

I though the Level on the Realiser had nothing to do for the second user...but of course it does.

 

And guess what, mine was set at at -30...

 

Problem not solved = there was no problem.

Do people use these for listening to music as well as movies? If so, what source do you use?

 

A Blu-ray can output a 7.1 DolbyTrueHD or DTS HD-Master surround source. But can you download music files in 7.1 surround sound anywhere? If so, how do you play them through the Realiser - do you connect to it using HDMI somehow?

 

Most music files are stereo rather than 7.1 surround - correct? I'm pretty sure most of my music collection is!

Hi,

There are plenty of multichannel audio, from CD DTS to DVD-A, DVD-VIDEO, SACD, or newly Pure Audio Bluray.

I don't think there are any files, available, legally.

 

I personnally don't really like 5.1 music, as most as I've heard are just playing with the 5.1 with no consistent with the recording itself.

I've bought many CD DTS years ago, then SACD for the improved quality, but most of what I'm listening to now is stereo only.

 

And the Realiser is able to reproduce a stereo installation.

 

When I'm not on the go, I'm only using the Realiser, which copies my small stereo installation (2 bookshelfs speakers and a sub).

 

It brings me a better experience, better than having the sound directly on the ears (even it is a trick).

post #2593 of 2713

Thanks, that's interesting. I didn't know about DTS 5.1 CDs. I'm not planning on buying a Realiser but I have a Marantz receiver with Dolby Headphone which can produce great virtualisations of 7.1 channel sound. I'd be interested in listening to some music through it.

I've had a quick look around and all the Pure Audio tracks I've been able to find are of old recordings. This means that they won't have been recorded in surround.

 

I think what I really need to get the most from my device (and you from yours) is music which has been recorded in surround. Some quick Googling shows that this isn't easy to find:

Quote:
 Most all modern movie soundtracks are recorded for surround sound. Very little music is recorded in surround sound

 

Quote:
 For music playback, not so much. Nearly all music is recorded for playback in stereo (i.e. with a front left and a front right speaker only).

 

I've sent out a couple of emails to see what music recorded in surround is available and where it can be purchased.

 

Edit:

 

This Blu-ray was recorded in 7.1 surround:

This Blu-ray may also be a 7.1 recording:
