I had mentioned that my Onkyo TX-SR606 was dying? The well known HDMI switching issue finally got on my nerves to the extent that it needed replacing. The replacement? A Sony STRDH820. Surprisingly, despite the brand it costs a lot less than the Onkyo (and Onkyo’s successor model) whilst providing you with more or less the same functionality.
The Sony unit itself is slightly smaller and lighter than the Onkyo, but sports the same glossy black front allowing it to hide in the corner of my room unnoticed until you turn it on. That’s where it starts to differentiate itself from the Onkyo. Like the old unit, it has an auto-configuration mode in which you plug a supplied microphone in, plonk it in the prime listening position of your room, and allow the amp to work out the distance between the speakers, the size of your speakers, and adjust various parameters accordingly. Now, with the Onkyo, I resorted to configuring these parameters manually because the automatic settings were rubbish – the front centre channel was dampened considerably by the automatic equalisation to start with! With the Sony, auto-configuration works perfectly for me and I’ve left it as it advised. Spatial separation of the channels appears to be much better in Pro-Logic II Movie mode with the stereo effects of TV programs much more obvious, and, I can’t be 100% sure, but it seems that the amp may be adjusting the vocals of TV programs dynamically to keep them at a steady volume, so even in low listening conditions, the vocals are clear (if slightly muffled on occasions).
I decided to include this photo on the left of the amp all connected up so as you can get an idea of scale compared to the Nintendo Wii above it. I do wish I’d dusted before I’d taken the photo though.
Anyway, back to the techie specs… I chose this amp for one main feature: Up-conversion. I have my TV on the wall quite a distance from the gadget boxes, and I have run a single HDMI cable up to it. The Sony STRDH820 will take any input source (component, composite or HDMI) and send it out of the HDMI port up to the telly. The Wii is now connected using component cables to give the best possible image, and my PS3 and Freesat box are connected by HDMI. The Sony will switch quickly between each source with no more than a second’s delay which to be honest is probably my TV thinking about it. If you aren’t fussed about the up-conversion feature, maybe you don’t have any analogue devices or maybe you are fine sending multiple cables to your TV and manually switching between TV sources and amp sources, you can save about £100 and get the STRDH520. But for simplicity, the 820 gives you much less to set up and think about.
What else? It supports 7.2 speakers… which consists of 7 surround speakers and 2 subwoofers, but I choose to run at a traditional 5.1 seeing no values in 7.anything at the moment. In fact, Sony haven’t made up their mind how 7.2 should work, giving you two options – the extra two speakers are either at the rear for a better surround effect, or up high at the front for vertical spacialization. Oooh, and it supports 3D. Well, by support, it’ll pass 3D images from a source device up to your TV… so it’s 3D ready in effect. I have a 3D ready amp, a 3D capable PS3, I just need a 3D TV to complete the trio. Another neat feature is the capability to customise the source label displayed on the LCD display. Not a massive feature I know, but a nice touch allowing me to display ‘Freesat’ instead of ‘SAT/CATV’ and ‘Wii’ instead of ‘Video-1’.
So, what don’t I like about it? This is probably what you are most interested in if you’ve landed on this review… So far I’ve discovered an issue between the amp and my Humax FOXSAT-HDR Freesat receiver. When you play a recording, or pause and play, or fast forward, or skip adverts, whenever the audio resumes playing you get a short burst of static. Everything works fine, but the noise is a bit annoying. I think it’s today with the interruption in the stream of digital data and instead of ignoring the corrupted data, it plays it. Another more irritating issue concerns the standby passthrough mode. Let’s say you wanted to watch TV, but didn’t want the extra oomph of the amplifier and were happy to use the TV speakers – like when CBeebies is on. Passthrough allows you to turn the amp off (or in to standby to be precise) and pass the audio straight through from your device to your TV. The Sony amp offers the ability to play the audio through ‘Amp’ or ‘Amp+TV’’. In Amp mode, audio is only ever played through the amp speakers, and in standby mode no audio is passed through to the TV. In Amp+TV mode, the audio is always passed through to the TV regardless, meaning that when the amp is on, you get an echo of the audio through the TV speakers as well! Now the solution to the problem is to use the latter mode and turn the TV volume down unless you need it. What the real solution should be is a third amp option to output Amp only when turned on, but passthrough to TV only when in standby. If you read this, Sony, please stick this in a firmware update.
