This means that the cable jacket is fire resistant and suitable to low-voltage in-wall applications. Note: In-wall HDMI cables have a CL2 or C元 rating. A wireless HDMI extender is much easier to install, can be easily relocated and can broadcast a high-resolution video signal to multiple receivers. Longer distances require an active cable or HDMI extender. in-wall HDMI cable or wireless HDMI?Ī cable connection is a relatively inexpensive option that gives a strong, reliable signal but can be difficult to install, it's limited to one location and a distance of 25-50-ft., depending on the resolution.

If an HDMI device may be subject to vibration or accidental movement, use a connector with a screw lock. HDMI connectors do not latch like DisplayPort connectors but some do provide a spring mechanism that makes the blade of a male connector grip the receptacle and makes it less likely that the cable will be accidentally pulled out. HDMI keystones are also available for digital signage applications and large conference facilities with many displays that are fed from a central location. HDMI faceplates give a clean, finished appearance and have a female connector on the internal side, making termination easy.

HDMI cable is considered low voltage so you can install it inside a wall. This could certainly explain differences in sound quality with the Denon. Now, if you use some type of direct mode on the NAD for CDs that eliminates the analog to digital and digital to analog conversions (no bass management or any other processing), you would be hearing the Denon's DAC only, as the NAD's ADC and DAC would not be in the signal path. In this case, the signal is ultimately converted to analog by the NAD's DAC, as is the case when the signal comes from a digital output like HDMI and optical/coax. The NAD would also have a digital to analog conversion prior to amplification. Assuming the Denon only has analog outputs and assuming you use bass management in the NAD, the NAD is most likely converting the Denon's analog signal to digital for DSP manipulation of the signal for bass management, channel delays/distances, etc. Interesting that the Denon sounds better to you. Technically, the HDMI and optical/coax should output the same 16/44.1 PCM signal for CDs, but might be worth experimenting with the optical/coax output for CDs. You might also want to try the Sony's optical or coax spdif digital output for CDs. I have the same Sony BD player are there are a few audio settings (like audio filter), but that would not apply to a digital output like HDMI or spdif. Thanks everyone - first step is to try the settings in the Sony Blu Ray player - it is connected through HDMI to my NAD. A decent, albeit plastic, transport, too - my main one has seen daily use for two years without a problem. The C-7030 has pretty good D/A converters considering it's <$170 street price. I tried to like our original Sony BRD player, the only one in the house with analog audio outputs, but compared to the C-7030 CDP, but recycled in my bonus/hobby room it just sounded flat - so I bought a second C-7030 to be used with my bonus/hobby room's system, which includes an Onkyo TX-8020 stereo receiver and a pair of R-15M speakers on my workbench. Stop by my office and listen to an Onkyo C-7030 CDP feeding my Emotiva A-100 mini-x and it feeds my Heresys and you'll hear the best music playing system in my home. Despite using the same speakers as my wife's music room stereo-only, Infinity Primus P363's driven by a Sony stereo receiver and CD changer, my Onkyo 7.1 AVR and year old Sony BRD player 5.1 HT - in stereo mode - just doesn't sound as clear as the dedicated stereo.

I have a 5.1 HT setup in our great room for programming and movies.
