Item: Emotiva BasX A-700: 7-Channel Power Amplifier Location: Melbourne, Northcote Price: $700 Item Condition: Excellent Reason for selling: Moved and changed set up. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Hey Guys, I’m selling here a great EMOTIVA power amp. Model: BASX A 700 It is a powerful 7 channel amp. In great condition and without any issues. I paid $1399 for it. Here the like: https://www.stereophonic.com.au/emotiva-basx-a-700-7-channel-power-amplifier/ Some specs: The BasX A-700 is a seven channel power amplifier. The BasX A-700 combines classical audiophile amplifier architecture - based on a heavy-duty linear power supply, and a carefully designed high current, short signal path, Class A/B output stage, with advanced, microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price. Power Output (two channels driven) 110 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.1%; into 8 Ohms 210 watts RMS per channel; 1 kHz; THD < 1%; into 4 Ohms Power Output (all channels driven) 80 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.1%; into 8 Ohms Power Bandwidth (at rated power; 8 Ohm load) 20 Hz to 20 kHz (+ / - 0.07 dB). Broad Band Frequency Response 5 Hz to 80 kHz (+ / - 1.8 dB). THD + noise < 0.02% (A-weighted); at rated power; 1 kHz; 8 Ohms Signal to Noise Ratio (8 Ohm load) > 120 dB (A-weighted); ref rated power. > 100 dB (A-weighted); ref 1 watt. Minimum Recommended Load Impedance 4 Ohms; which equals one 4 Ohm load or two paralleled 8 Ohm loads. Damping Factor (8 Ohm load) > 500. Speaker Output Connections Audiophile grade, 5-way binding posts. Photos: Advertisements without photos of the actual item will not be approved.
The NAD T478 (v1 I suppose you could say, since its not the V2) is the entry level AVR from NAD. Pros: Can be purchased for under $600 now - entered the market closer to $1400 Very clean detailed sound in driving my Focal bookshelf speakers. Will process almost anything you throw at it. HDMI 1.4 with video pass through so you can watch TV without it. Sources can be renamed to suit your needs. Display is easy to read and can be reconfigured to show Source, Audio Listening Mode or Source format (i.e. at what sample rate and resolution your incoming data is e.g. 24/192) 4 HDMI inputs, one output 2 optical inputs 2 coax digital inputs 3 analog inputs 7.1 pre-outputs for connection to external power amplification 7 x 40 W all channels driven 2 x 80 W in stereo only Analog inputs really do bypass all DSP in Analog Bypass mode - so using an external DAC can fully replace the onboard DAC if you can't resist that sort of tweak - but only in stereo. You still get bass management so your SW is still going to deliver the bottom end for music if you need it. Speaker settings are fully configurable manually User friendly remote - buttons do not stick and unit always responds quickly < 1 sec delay on switching sources Cons OSD looks clunky but is uncomplicated While listening to any digital source using the OSD interrupts audio Room Correction software is really nasty - I did not like the result at all (but can be ignored) 40 W per channel is just a bit under powered if you like your movies loud not upgradeable My Observations Bottom line - if you like clarity and warmth in Audio and you want to watch the latest video formats with out unnecessary bells+whistles then this is excellent value indeed, especially for a smallish (I'm in 16 m2) acoustically dead room. As noted above you can run the Autocalibration of your speakers with the provided mic but I hated the result so I have set it by ear and I really like the resulting sound. At the top end NAD AVRs have Audyssey which I believe is superior room correction and I guess I'm just lucky that my room is so forgiving and really needs little correction at all. You may not be so lucky. Like many I can't help tweaking to see if I'm getting the best out of my gear so I've put a lot of time in setting the speaker settings and after about 6 weeks of intermittent experimentation I have a result that sounds excellent. By far the biggest headache is the inconsistent quality of source material, so there's always some extra adjustment that has to be made to get the current source just perfect. Most often its adjustment of the SW volume. I don't expect that there could be a system, no matter what cost, that will get past that. A poor recording is a limitation of its own, end of story. Sure with my external DAC everything gets upsampled to 24/192 kHz so lots of recording sound better, but some never sound actually good. Good recordings sound good it goes without saying. So I'm a pain in the ass wearing a track in the carpet to the SW. However the Cirrus Logic on board DAC in the NAD does do an excellent job with anything you give it so it's not necessary at all to go the external route. I only did it because I'm Audio OCD and because the V-90 is so cheap ($400) for the quality inside it, so I thought I'd try it out. I first encountered NAD gear back in the 1980's and was impressed as a young fellow so when I could I bought the legendary 3020 amp - which still works and sounds very good indeed. So when it came time to get an AVR there was in my mind no competition and not being rich I bought the T743 in 2005. Recently it developed an intermittent error in its thermal protection circuitry which would switch it off even though the things was cold to touch. So rather than pay $400 to have it serviced I $800 and got the newer model, on the cusp of it being superceded by the V2. Hence the bargain price. Adding the XPA-200 Power Amp 2 x 150 W Class A/B (see the Emotiva site for specs) So I'm listening away and pretty happy and then I come across this company in the states called Emotiva. They make audiophile gear at very low cost. They only sell on the internet, but even with shipping you can buy a power amp for a fraction of the cost of what's in the high-end stores here. So then I'm looking at the pre-outs on my NAD and thinking a bit more on the front L+R channels might free up the other 3 channels and make a difference. I had some cash on hand so I shelled out $650 to import the XPA-200. It turned up in 5 days. Connecting it was easy, just a pair of RCA's from the pre-out of the NAD to the inputs of the power amp, then disconnect the speaker cables from the NAD and connect them to the amp. With banana plugs it was a five second job. Is the additional power too much? No. My speakers, which Focal recommend feeding with 100W, are perfectly happy with it. Can I hear the difference? Yes, but it's subtle. You see extra power does not just mean extra volume, its extra dynamics and clarity and a listening experience that is full of intangibles. I like it. My wife who claims not to hear any difference was obviously enjoying her favourite tunes more than she normally does. I've tried it out in both stereo and multichannel mode now. In stereo and in Anaolg Bypass on the NAD the Emotiva is driving the L+R speakers alone and it sounds beautiful with anything that I already know to be well recorded. I have an eclectic collection of music in terms of styles and most of it shares the attribute of being more demanding listening. I have a few hi res recordings too, some in 24/96 and a few in 24/192. All sound excellent and like I said I'm Audio OCD who thinks that playing toons straight out of a phone is crime against music. In 5.1 the difference is very much more apparent. Now the NAD is delivering what is has to 3 channels not 5 and it the extra power into the front channels is exciting and a very positive experience. With 5.1 mastered music (Pink Floyd DSOTM SACD, Talking Heads Speaking in Tongues DVD-A, King Crimson Discipline DVD-A) its very satisfying indeed. Get the bass right in the first 30 sec and then just listen...no urge to do anything but immerse in the sounds. Same experience with video, The Lord of the Rings, Prometheus & Apocalypse Now all sound quite incredible on my gear. Bottom line - if you have a smallish dead room and don't need sophisticated room corrections, then for $800+$650 you can have what others are paying $20K for. Price tag is no indication at all of quality. Thanks for reading.
