Got HK DPR 2005 today..

[Lou-the-dog]

Abhi, thanks for sharing your impressions. Looks like the HK2005 is definitely worth a listen.

Now I'd REALLY be curious to read of somebody ABing the HK2005 against the Panny sa-xr55...

How are you able to set "ohms" in the receiver? I have never heard of this. Is this possible in their analog receivers?

I'm not sure about their analog receivers. Here is a snippet from the manual:

Speaker Optimizer
The Speaker Optimization function is critical to ensure
optimal performance of the DPR, as it tells the digital
amplifier section how to best match its operation to your
specific speakers. Note that this adjustment is electronic,
not electrical, and unlike the “8-ohm/4-ohm” switches
on older analog amplifiers, you do not need to turn the
DPR off to change the setting. However, we do suggest
that you do not have any program material playing
through the DPR when the setting is changed.
Before making this adjustment you will need to find the
impedance specification for your speakers. This information
is often found on a label attached to the speaker,
and it is usually shown in the owner’s manual that came
with your speakers. If you cannot find the information for
your speakers, consult the manufacturer’s Web site or
customer service department.
In cases where the speakers in a system have different
impedance ratings, such as 8 ohms for the front left/right
and center speakers and 6 ohms for the surround
speakers, use the setting for the front speakers, as they
are used most often for all types of program material.
If you cannot determine the speaker’s impedance, there
is no harm in using the factory default setting of 8 ohms,
as most home speakers are in that range. However, if it
appears that your system’s performance in the highfrequency
range sounds constricted at high volume
levels, you may want to experiment with the 6-ohm or
4-ohm setting.
If your speakers match the factory default setting of 8
ohms, no further adjustment is needed, and you may exit

I don't think the analog HK's have an ohms setting.

One of the few things I still find annoying about my HK 635 is the heat -- it gets hot, and is rated as using a lot of power.

Does the DPR 2005 use less power / give off less heat than an analog amp?

It gets warm. But not as warm as my Denon. Not sure about 635 though.

With a 2005, you can keep your hand on it, but it's quite warm. Can you keep your hand on a 635 running all channels?

Why does the heat bother you so much? In enclosed cabinet? Isn't that how analog amps are?

[Kurt C.]

My rather crude understanding is that even when analog amplifiers aren't delivering high current levels to the speakers, they have to act as a heat sink to dissipate all that unused power. That's one of the main reasons they get so hot. Digital amps are different because when they aren't delivering much current to the speakers, the power can be essentially turned off. This results in much cooler operation and less overall power consumption.

While I was enjoying the DPR 2005 in my setup, one fine day it decided not to pass the video through and not to output sound either.... And it goes back to the store!

Back to the Denon. I gave a second thought to the calibration process. In comes the Avia DVD from NetFlix. Recalibrated the Denon using Avia. Test tone sounded very different from the Denon's. Obviously the result of level settings was also different. Test played few CDs. The heftiness to the sound which I observed through Denon before had gone. The sound was quick, light yet the bass was ample, but tight. The differences I observed with the DPR and the Denon became very narrow. Last night watched KillBill2. When Uma Therman was buried, the sound of nails, hammer and sand put a big smile on the face.

Afterall, sound is sound. It can only be categorized as either pure or distorted. There is no analog vs digital sound in my book anymore! :-)

What'll be my next upgrade? Well, I'm waiting for Denon 3806 with the state-of-the-art MultEQ! :-)

Enjoy!
