Audio Research Corporation, the company that almost single-handedly created high-end audio electronics, not to mention preserved the vacuum tube as an amplification device, recently revised its basic line. Starting out as the VT80, after a short production run the amp was upgraded to the VT80SE, of which the review unit was the first production sample. Audio Research uses the upgraded KTs in all its amplifiers. All Foundation Series equipment shares similar stylistic features, making them a recognizable family, which must be helpful at hi-fi shows. Otherwise, the VT80SE is a large, low, open-chassis amplifier with a typical layout: transformers and output tubes in the rear, input tubes in the center, input and output jacks on the vertical rear panel. The original VT80 incorporated one of the biggest tech advances in Audio Research history, an automatic biasing system aimed at reducing the routine annoying maintenance required when you use a tube amplifier—prompting a rousing hooray from me!

The classic of the time if I remember correctly was an Audio Research preamplifier feeding a big Krell power amp and a pair of Celestion SL6, and later SLs moving the air. Needless to say, the dream front end would have hailed from Glasgow. However, the story of Audio Research goes well back before the mid-eighties and my minor obsession, with a Minneapolis company called Electronic Industries headed up by a guy called William Zane Johnson who launched a three-chassis mono amp in with Audio Research Corporation being formed in …via Bill working for and having sold his designs to a company called Peploe.

In the VT80SE you get a massive 75 Watts of power per channel which should be enough to drive even very demanding loudspeakers. The VT80SE handily uses auto-biasing circuitry and so set up is simple and straightforward — no meters and no inserting screwdirvers.

Insert valves, wire the amp and pre up to a source and speakers as per the norm and off you go. Round the front, you have the on button and when pressed the amp goes into mute mode for thirty seconds. You get a valve cover too to protect valves from accidental damage or prying little fingers but why would you want to hide those tubes — or so I thought until the cat showed an interest!

All in all, everything looks to be very well put together and with high-quality components being used throughout. Add a Made in USA and a three-year warranty and there is a good degree of confidence in this being a product you could rely on for years to come. The LS28 is a line-stage only preamplifier AR make separate phonostages too for vinyl aficionados offering four balanced and four single-ended inputs with two single-ended and two balanced outputs plus an output for taping, which is a nice touch and not always seen on preamplifiers.

The front panel is nicely laid out and you get a step rotary volume knob and the same the other side to select input. Also on the front are buttons for power, menu, enter, mono and mute, but in all honesty pretty much everything you need can be done on the very nicely made remote control that is weighty and is ideal for the armchair enthusiast.

Indeed, if you are streaming your files, as I did for the duration of the review there is no need to move from your chair other than for refreshments. The front display is easy to read from a distance and is understated even at full brightness, but should you wish you can dim it by several notches or turn it off completely you can — I actually quite liked it glowing green at full brightness.

Set up of the pair is a doddle with everything being nicely spaced on the back panels allowing for plenty of space for cables. Plug everything in, let everything get up to speed, choose your input channel, turn up the volume and play your tunes. Speakers were Xavian Perlas which, despite their relatively modest price-point, proved an excellent march for the Audio Research power and pre.

One thing I did find useful here was the balance control which I had set one notch in favour of the right-hand speaker, allowing me to really snap the stereo image into focus from my chair. Anyway, as I said, I ended up listening to this record all the way through and was really drawn to the vocal performance that was presented with ease and clarity without a hint of harshness or feeling things were being pushed, despite me listening at relatively high volumes 20 on the pre.

Detail was there in buckets and I was particularly drawn to cymbal splashes on Jezebel that just started and stopped as they should. Even at loud volumes I never felt I was getting too much information or that one frequency was dominating proceedings and this is a very good thing. Balance and poise were my first impressions from this pairing but on rockier sections there was grip and power and no hint of the amp being anything but in control of the speakers.

Mandolins were clearly distinct, fiddles likewise, and holding it all together the beat was presented rock solidly. Play it on a great system and what you actually have is still a brutal assault on the self, but one that is full of different textures and tones, and that is what you have presented with the Audio Research pairing.

Listen closely and what may have appeared to be just a noise is actually made up of several different noises that combine to make the whole. Over analytical? Not at all! I think the thing when folk say a particular piece of equipment or system is over analytical is that the top-end has been artificially boosted. What we have here is to a great degree the reality of what is coming out the DAC. Having that little mid-boost allows you to hear more of the tone and more of the texture of the vocal and I think this will appeal to others also.

What I am saying is that in this system and to my ears the mids are ever so slightly lifted in the mix. Although complete overkill on the power front I put this combo onto the Avantgarde Duo XDs which are around dB sensitive and have active bass. I did this for a couple of reasons: 1.

To see if it would be worth investing in such a powerful amp and 2. Because I could and I thought it would be fun. It was fun and proved to be a really wonderful partnership. You get that wonderful ease of sound but with the detail too and the Avantgardes just allow the Audio Research kit to sing even more.

I loved it! There sometimes comes a point in reviews and you ask yourself, can I afford or warrant another purchase of kit? They are by no means cheap products, but what they bring to the table is a true audiophile listening experience that is both detailed and expressive, but they also connect you emotionally with the music you are listening to. I liked them a lot; they give the feeling that whatever you throw at them it is they that are in control of proceedings and in all my time with them and with whatever music I played through them they never once felt anything but sure-footed and poised.

They have power in reserve in the system I used them in and never once did I feel like they were running out of steam or struggling with fast changes in dynamics. Words I want to use are speed, agility, poise, air, grip and detail. I also want to say that I feel the amp is like a very well executed B amp but with real balls in the bass department — I want to say this because of the really beautiful and slightly pushed mids and I think this is down to that wonderful KT tube.

On the other hand, the source selector knob and remote knob were both excellent to use. Some people may find the power amplifier difficult to accommodate on their rack as it is very deep, but if you are spending this kind of dosh then get something made.

What we have here can certainly be classed as high-end product and whilst not cheap, they certainly give the listener a desire to hear what products further up the Audio Research line-up can bring to the listening experience. Build Quality: Build quality reflects the price and is excellent. My only gripe was the buttons on the preamplifier but then the excellent and weighty remote made them pretty much obsolete in day to day use.

Those handles on the front are the icing on the cake. Sound Quality: Controlled and speedy but with poise and detail too. A wonderfully non-fatiguing listen with detail aplenty. Pros: Build, looks, great sound and a huge pride of ownership factor. Power and poise in equal measure. Cables by Tellurium Q, Chord and Atlas.

I just want you to let me know that I am a proud owner of this fairly new DAC. For my ears, the network was superior sound quality. Clearer, more open, transparant etc. To my surprise to be honest! What a brilliant combo. Superb speakers.

Audio Research Reference 75SE stereo power amplifier

LOG IN. The Lumi is deservedly a legend and has a fabulous phono stage, to boot. At the same time, I enjoy listening to subtle details that more syrupy components can obscure. Unfortunately, I cannot audition anything prior to purchase, neither in my home nor at a dealer.

Audio Research Reference 75 review

The Auralic Altair G1 digital audio streamer is rare in the world of high end audio. Most of us are used to single-purpose components that require numerous add-ons for additional features or components that are multi-function but serve as a jack of all trades, masters of none. The Altair G1 is rare because it provides consumers with nearly everything they want, does nearly everything right, and is relatively inexpensive compared to the other options in this often crazy world of HiFi. I used the Altair G1 for a few months, giving it a workout the likes of which it hadn't seen before and may never see again. I know this because the team at Auralic frequently told me this was the case.

Review: Audio Research VT80 Foundation Series power amplifier

Every month Stereophile magazine offers authoritative reviews, informed recommendations, helpful advice, and controversial opinions, all stemming from the revolutionary idea that audio components should be judged on how they reproduce music. US companies have been doing it since the s, when it was discovered that multiplexing—the then-new practice of combining multiple signals over a single conductor—could be used to send live or recorded music over public power lines. The first of those companies was Muzak LLC. File that away. In the middle-class world in which I was raised, my family had a tidy little house, plenty of food, clean clothes, and excellent medical care. My sister and I attended good public schools, and we lived in a neighborhood where there were lots of other kids our age.

Probably no other name in high-end audio enjoys the reputation, recognition, and respect of Audio Research. Electronic Industries was the springboard allowing Bill to bring his ideas and designs to light as he designed sophisticated amplifiers for customers demanding the finest music reproduction in their homes. In , Bill sold the company, his designs, patents, and himself to Peploe, another Minneapolis company. Working for another company did not last very long, and after two years, Bill bought back everything and founded Audio Research Corporation in Since the beginning, Audio Research has maintained a fanatical devotion to quality and sonic performance. The has kept them at the very top echelon of manufacturers in the industry. To that end, every single Audio Research component is personally auditioned by Warren Gehl before it leaves the factory.

So how can we create the same shivering adrenaline fix that we once so easily could when we were younger and stronger?
