Connectivity is pretty solid for an HTIB in this price range. Most impressive is the HDMI connectivity--not only is there an HDMI output capable of upconverting DVDs, but there's also an HDMI input to connect one digital high-def component. (Add a cheap HDMI switcher, and you can triple, quadruple, or even quintuple that capacity.) For analog video, there's a component video output and a composite video output--but note that there are no other video inputs, which would have been a nice upgrade. There are however, three audio inputs--stereo analog RCA jacks and an optical digital audio input on the rear panel, and a minijack input up front. You can still connect a video component to the HT-X70 by running the audio cables to the HT-X70 and the video cables to the spare input on your TV, but you'll have to do some remote fumbling to switch the inputs on both devices--you'd be wise to look into buying a universal remote to handle the duties. There's also an XM port, which means you'll only need to connect an XM Mini-Tuner to get reception--provided you have a subscription, of course.
You'll also notice there's a slot in the back that says "Wireless." This is used for interfacing with Samsung's wireless rear speaker system, the SWA-3000. The SWA-3000 comes with a TX card, which you slide into the slot, and then it can communicate with the base station, which connects to the rear speakers. Of course, you'll still need to plug in the base station, plus run speaker wire to each speaker--so there are three cables in this "wireless" solution--but at least you don't have to run cables from the front of the room all the way to the back.
Many buyers may be disappointed by the HT-X70's iPod compatibility, especially considering it features the "Made for iPod" logo on the box. We appreciated that the HT-X70 came with an iPod cable, which has an iPod connector on one end and a USB and minijack cable on the other. That struck us as strange, but we proceeded to connect an iPod Nano using both cables anyway. When we selected the USB input on the HT-X70, our Nano went into "connected mode" and we were able to browse the folders on our Nano--with one big problem. When we went into music, we could only see folders named "F01" and "F02," instead of artist names. A similar problem existed with the actual files, as they were named just a random series of letters instead of a song title. Clearly, that's not an acceptable solution. Switching the input to Aux 1 was a better situation. This basically just treated our Nano like any other external audio device--so we had to browse for songs on the Nano instead of using an onscreen display--but this was preferable to the USB connection. Given these limitations, we think the "Made for iPod" claim is a bit of a stretch.
We started off our test of the video quality performance of the HT-X70 using Silicon Optix's HQV test suite. The HT-X70 got off to a good start with the first resolution test, demonstrating its ability to display the full resolution of DVDs in 1080i mode, although it failed in both 480p mode and 720p mode. The next few tests weren't good, though--playback was jerky and filled with jaggies on tests depicting a rotating line, three pivoting lines, and a flag waving in the wind. It also had a difficult time with the HQV's 2:3 pulldown test--it clearly failed as it never kicked into film mode, resulting in moirÃ© in the grandstands as a race car drove by. Performance wasn't much better with scrolling titles, which were filled with jaggies and some distracting "flashing" behavior.
Of course, we looked at some actual content, too, and the HT-X70 did considerably better. It did a very good job on the difficult Seabiscuit test, exhibiting none of the jaggies that we often see on this disc. We also were able to confirm that the HT-X70 does have 2:3 pulldown processing by watching the introduction to Star Trek: Insurrection, as it was able to render the smooth hull of the boat and railing of the bridge without any jaggies. So while the HT-X70 may have struggled on some of the more difficult tests on the HQV test suite, less critical viewers probably will be satisfied with the image quality performance on DVDs.
For music, like many bargain HTIBs, the HT-X70 came up a little short. We started off with Duke Ellington's Money Jungle, which sounded pretty good, although we thought the acoustic bass sounded a little unnatural and less musical than we'd like. Moving onto Jeff Beck's hard-rocking Truth revealed some more low-end deficiencies, and the bass got pretty boomy when we started to crank up the volume. The front speakers were pretty good given their size, but audiophiles will definitely notice they're less detailed than even relatively cheap standalone bookshelf speakers. We also tried the Fiery Furnaces' excellent Blueberry Boat, which probably sounded the best out of the three, but we still cringed a little when the subwoofer couldn't handle the bass. Our gripes aside, the HT-X70 delivers a pretty average sound for this kind of HTIB, so less critical listeners probably won't notice the difference.
On DVDs, the HT-X70 did a much better job. It allowed us to get fully engaged in Pirates of the Caribbean: The Curse of the Black Pearl, especially the somewhat eerie introductory dream sequence. Dialogue intelligibility was solid, and the problems we had with the subwoofer were much less noticeable during the movie. Unless you're an audiophile, the HT-X70 will get the job done with DVDs.
