oppo's volume control

No assumptions Runnin, no need to get defensive any tech will tell you, just look at the factory specs on your P7, the FR (frequency response) is curtailed at at 5hz!! this means it's capacitor coupled within it's circuit, for if it was not capacitor coupled the specs would show DC -100khz.

Yeah, I just looked up your track record on this forum, George. Seems you hate preamps, and have posted again and again on how bad they are, and don't seem to realize you're getting a bad reputation around here.

You were wrong about Oppo's having an analog volume, wrong about Oppo's having output impedance under 200 ohms and wrong about the P7 having caps in the signal path. I'm not going to do any more research on your claims George. When called out about the above, you simply ignore the facts as if they don't matter since they disagree with your world view. That's kind of weird.

The thing is, I no longer can trust you know what you're talking about or that you aren't a 19 yr old kid sitting at his mom's computer trying to get other posters worked up. Go see Godzilla or something, kid.

Another update, so you're on this forum, it seems you market some kind of preamp like device that's like a straight wire with gain. Good for you, but you, as representing a company, you shouldn't come on forums and slag other companies. That's bad form.

And it's odd that you'd make posts about Oppo's volume and output impedance when you were so flatly wrong. So the P7 has such and such at 5 Hz. Can't trust it means anything just because you say so, as a guy trying to sell something, and as a guy so wrong about the Oppos. You haven't even taken the top off the P7, just going by the spec sheet.

At the end of the day, I'm REALLY not interested in what you have to sell.

If you have any technical knowledge at all Running, you would know that a limited lf frequency of 5hz is only done by having capacitors coupling, in the signal path or in the feedback network of an active preamp.

And you are in a state of confusion as far as accusing me of promoting my Lightspeed product I have not done so at all in this thread, or slagging other products, all I've stated is that direct from the source is the most transparent way of transferring the source signal to the poweramp if all impedance are correct and voltage output is high enough, and in this case the Oppo has all the factors covered.

If clicks and pops are heard it's not the fault of directly driving to the poweramp, or in the far fetched notion of static build up in the same interconnects as when used with a preamp, but the noise trouble imitates from the source itself, and that the dc coupling of going direct is letting it be heard.

Cheers George

Moving the debate on....although personally I wouldn't put anything direct into a power amp other than an Oppo 105-that's the machine designed for optimum stereo playback....I have had the chance now to try the Oppo in this mode.

I've upgrade my amp to a Rega Osiris which has the ability to take a direct input.

The first thing I noticed due to the gain differences is that at volume level 1 on the Oppo is pretty loud as a starting point (0 is mute) although I've ordered some attenuators to see how that works.

What I do prefer is that the Oppo gives a much tighter volume control that the Osiris itself-that 0.5db increase is nice.

I haven't done this particularly analytically and I don't have a sound meter but I have a quick A/B using Beck's Sea Change (HDCD) and Radiohead's OK Computer.

To me the most obvious thing is that going in direct has a much more closed in sound-my speakers neither project the detail or 3D sound staging. It is noticeably different and possibly the change in presentation (I've only had the amp 4 days and only listened normally during that time) is off putting and I'm missing some positives but my gut reaction off the bat etc etc is that in my system with my amp going direct seems inferior and noticeably so.

I will return to this in more detail later as I do prefer the volume control steps via the Oppo.
