Exemplar Denon 2900. WOW Need owner advice.

I am the very happy owner of a Exemplar Denon 2900. What an incredible player. For you other Exemplar owners:

Two questions.

1. Do you leave the unit in "Standby" mode or do a hard shutdown with the main power button? Anyone know what John Tucker recommends? My concern of course is heat and shortened tube life if left in standby.

2. Do you utilize the "pure direct" mode- shutting off video functions? Is it worth it to do so? (My Stereo rig is completely seperate from any video display...to use "Pure Direct" I'll have to drag a monitor in and temporarily connect the Exemplar 2900 to it to shut the video functions off.)

I emailed John Tucker with these questions,but I think he's working 28 hours a day building units- I have'nt heard back from him.

Thanks in advance for your advice!

Tbg, while I believe you hear what you hear, your statement that
There is a very obvious improvement with
everything off.
does not mirror my observations,
and therefore others should be advised that they may or may not hear
any improvement. I am also using 7062 tubes.

This week, I'm going to treat the tubes, connectors, etc. with CAIG De-
Oxit and Pro Gold. I'm interested to hear the difference.

Thanks to all of you for your help. I disabled the video out and digital out signals, and I'm now running in Pure Direct mode.

I am also now turning the unit off via the remote- putting it into "Standby". The tubes remain lit, but heat generated above the output tubes is minimal.

I'm thoroughly enjoying this unit, and I'm finding it very sensitive to power cords and interconnects. Any feedback on what you guys have found to work best would also be appreciated!

Thanks again guys!

Tvad, you are wasting your time with the CAIG De-
Oxit and Pro Gold. As I have mentioned elsewhere, the new AudioTop makes the other contact enhansers I have used sound half-hearted. I do not know how some such treatment could so far surpass others, but it does.

I must say that I am perplexed to hear that you fail to hear any improvements. I know four others who have heard clearly superior sound with the video and digital off. The display being off make less difference.

Danlib1, I entirely agree that the Exemplar responses to power cords and interconnects, as well as to isolation. I use it on the Neuance shelf on a level 5 Mana stand. Presently I use the Omega Mikro power cord and the Acapella interconnects, although the Indra gives a wider and encompasing soundstage.

Well, Tbg, I know of one other in this thread, Eldartford, who has also heard no discernable improvement with video and digital off, so I can surmise we aren't the only ones.

Audiotop at $316/kit is way beyond what I'm willing to spend for cleaner and protectant. Since my ears don't appear to be as golden as yours, I'll start with my $40 investment in CAIG products and go from there.

Tvad....Just a guess, but maybe tube electronics, which circuits run at much higher impedance that transistors, might be sensitive to digital noise pickup.
