Dudes!

You're on my level...tongue.gif



Particularly like the coffee maker suggestion biggrin.gif

Does anybody know the output impedance for both the XLR and RCA outputs on the preamp stage? I know the output impedance for the headphone stage is 0.5 and 0.7 ohms, respectively.

Maybe I'm dumb, but is there a way to extend the screen for the spectrumeter? By default it shows 100-10k, I'd like to see 20hz-20k.

The range is not adjustable.  Would be a nice feature for a future firmware update.

I had both the Asgard 2 and the HA-1 beta test unit at the same time.  The Asgard 2 gets a bit hotter, and the volume knob does get quite warm.  I'm not so sure I'd set a monitor on top of the HA-1.  Probably be OK, but I wouldn't do it.

One the one hand, I agree.  On the other hand, I've probably spent 10 minutes with the spectrometer display since the beta test started back around Thanksgiving...

If I remember correctly, Oppo did expand the frequency range, or label it better or something during the beta test.  20 Hz to 20 Khz seems the reasonable range.  The bars would get pretty thin though, not a lot of screen real estate.

 

The spectrum and VU options are cool, but I think I've spent 10 minutes each with them.  I just use the info display, or more often, dim it to no display.

The HA-1 sits on my desk and I love looking at the spectrometer. I could see if it weren't in vision then it wouldn't be something of importance though.

Aromatherapy is included, but it's a one-time use feature. I think it's described in the manual under the warnings section. Something about water or shorting out connectors.

There are plenty of products out thee for people who think they need that kind of band aid.

Are these actually available yet? If so and anybody has one I would really like to know how the headphone amp portion sounds with HD800/650 (High Impedance) and Grados (No specific model as they all have the same impedance but maybe some RS1i). Thanks

Originally there were no labels, then values were added, 100 hz, 1 khz, 10 khz.  The 100 hz to 10 khz range was selected to provide FFT analyzer (spectrum) view of audio levels without running into erroneous information from bass information. :)

The Spectrum Visualizer is logarithmic, so you run into major issues with how to display the spectrum if you include the full audible frequency range. Since it is primarily a visualizer, and not a professional tool for analyzing the frequency spectrum, we were concerned about how dynamic the screen would be if we had a 20Hz-20KHz spectrum visualizer range. A large part of the screen would not produce any results past 12.5KHz, for example, which is just a waste of the available (but limited) screen space. So we ended up cutting off the at 100Hz-10KHz, with "<100" encompassing all frequencies 100Hz and below, and ">10KHz" encompassing all frequencies 10KHz and above.

Makes sense, thank you for the detailed explaination.

x3 Thanks for the detailed explanation. I don't mind not having it display much above 12.5kHz, though up to 15kHz would be welcomed. ;-) But I'd REALLY like to see individual bands down to 20Hz...let's say, "20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 80Hz, 100Hz", or at least start the low end display at 30Hz. I don't mind that each of the "bars" would become thinner or narrower. IMO, there is A LOT happening below 100Hz that I would really like to see (individual bands, not everything <100Hz grouped together).

I'd also like to see the VU meters become larger overall somehow, with a larger font and the option for thicker lines/scale demarcations and a thicker needle. I love the overall look of the current VU meters (reminds me of my old professional Nagra recorder), but they don't seem to make very good use of the large display on the HA-1. I can't really see them from more than 3-4 feet away (maybe just my old eyes). The Squeezebox Touch VU meters are much more visible even though the actual display size is almost identical.

The only other niggle I have...while I'm on my "rant", tongue.gif ...is that the remote is very slippery and I wish the bottom corners were rounded-off...they are a bit sharp where the corners rest in the palm of your hand. The perimeter of the top edge is quite sharp as well...it would be nice to see a slight bevel along the top edge, similar to the iPhone 5/5s.

Otherwise, it is a fantastic unit with absolute ToTL sound quality. smily_headphones1.gif I just might be persuaded to purchase one . wink.gif I'm judging all of this off of a friend's recently aqcuired HA-1.
