I recently switched to a USB DAC that included an outboard power supply with its own regulated 5V rail and no longer need my Intona (Industrial Version). It's in "like new" condition, with the original box. It was easy to hear its effect with my previous DAC, which had a built-in PSU.

The price is USD $250, with free shipping to any USA address. Depending on the final package weight and service requested, shipping to most other countries is about $14-$29. Credit cards via my business's secure server are accepted, as well as PayPal.

You should be able to reach me off-forum by PM or eMail to audio@tempoelectric.com

Cheers,
Joseph

Thanks to You and the gang, I've discovered/enjoyed more music in the last year, than years before combined. Happy

 Another year has passed so quickly   Happy

 I am for the last year/s truly enjoying the Oreleo/phasure experience.

 I have had Grammy winning artists,  Recording engineers/ultra high-end speaker manufacturers, John Doe speaker manufacturers, novices all visit .... with great feedback  Wink

 Although difficult to describe I would put the musical presentation as acoustic virtual reality, the equivalent of visual virtual reality ...

 A picture speaks 1000 words, most speak about the walls disappearing, haven't heard anyone describe the floor and the ceilings are disappearing or something like this  ....

Hi again Nick,

Quote
In the real time FFTs of low frequency sweeps Iv been looking at, and just as you said, when cone excursjons are large those second harmonics are present !

Yes, but it is to keep in mind that calibration takes place (has taken place) under the strict condition of 89dBSPL (no more but also no less in order not to fool ourselves). And *then* the excursion is within range in such fashion that no audible distortion occurs (and excursion is maybe 0.5cm (but I forgot)). Thus, 20Hz remains that (no 40Hz audible). 19Hz remains that. 18 ... all the way down. This is all arranged for in the DSP (per my preset of course). It could be a good idea not to mangle there and take very good care of understanding the principles first (which is exactly whay you asked of course !).

Kind regards,
Peter

Peter hi,

Thanks, for all the very useful information.

I assumed that you would not have used the NOS and XX as the calibration signal source for some of the reasons you gave but just needed to double check. But very good to get it confirmed so I can cast my attention back towards my room and pc setups and trust the DSP curve.

In another answer where I spoke about relativly large bass cone deflections you mentioned that these large excursions generate second harmonics. In the real time FFTs of low frequency sweeps Iv been looking at, and just as you said, when cone excursjons are large those second harmonics are present ! This is not too much of a concern whilst listening though as the bass sound quality is still superb.

On a happy note, its very difficult to overstate the transformation in bass sound quality that the dsp tweeks to compensate for rear wall and corner reinforcements have made. So as not to go off topic in this thread I will start a new thread on the tweeks, it just may help other owners.

Regards,
Nick.

When you generated the bass response curve for the Orelo IIs, that you put up in the graph in the first post in this thread, were use using your NOS1 and audio PC to generate the sweep signal that was sent to the speakers or did you use another device such as your DScope to create the sweep input to the speakers ?

Hi Nick - Question of the year !

The answer is, No, it is not allowed to use the NOS1 for this. This is because you wouldn't be using XXHighEnd to play the signal (well, you could, but using e.g. REW would be more logical and intuitive) ... and then the reconstruction filtering would lack, which the NOS1 requires (well, in my own thinking of course and I suppose every NOS1 owner happily agrees).
I fell in that pitfall myself after noticing the relatively heavy roll off of the highs. Never looked at the bass because I didn't get round to that. I just started using the output of my ADC (which is also a DAC).

What you could have observed is the relative more pronounced signal, the lower the frequency. Thus, the roll off with "genuine NOS" is there right from the start (lower frequency), increasing more and more towards the highs. Thus any swept signal would be loudest in the bass ...

Best regards,
Peter

PS: You might also want to consider the pandora's box when you realize that playing through XXHighEnd and its diverse settings and various Operating Systems for that matter, will let (physically !) feel the woofers different in each situation. Take distance of that or you will get mad. Thus, this signal generator you will be using (like from REW or hardware etc. etc.) WILL express only one of these 100s of situations only, and you can not change that. It will never represent your playback reality ...

Peter hi,

Im doing some work on room matching my Orelos IIs, I'm very pleased with results so far. I have always had significant bloom in bass due, I think, to rear wall / corner interactions. I have appiled some simple DSP adjustments that have vastly improved bass reproduction. I will post the method used in case it is of used to anyone else when I'm satisfied with the results.

Doing this has raised a question if you could help.

When you generated the bass response curve for the Orelo IIs, that you put up in the graph in the first post in this thread, were use using your NOS1 and audio PC to generate the sweep signal that was sent to the speakers or did you use another device such as your DScope to create the sweep input to the speakers ?

The reason I ask is that with my current setup I am getting some significant driver excursions at  20 to 30 hz when I am playing sweep files through my NOS and when playing a few tracks with very low bass effects dubbed into the track. Im trying to work out where to focus attention to deal with this and it would help to understand how the the origional calibration took place.

Thanks and regards,
Nick.
