My Audio Research experience


To all you goners out there, here is my experience with Audio Research.

Approximately four years ago I purchased an AR Reference 75 power amp.  It was on special at the time and I bought if from a dealer in Brisbane, Australia.

I used the amp for the rear channels of my home theatre system which I only use occasionally because I travel a lot for work and I mainly listen to music.

One night I switched the amp on and a white flash and burning smell came from the amplifier and it didn’t power up.  I thought it may have been a tube, and because I had no spares, I reported the problem to my Brisbane dealer and via email to Audio Research.  A copy of the reply sent from AR on the 5th March 2016 follows:

'Thank you for choosing Audio Research and the REF75. I suspect you had an internal tube arc. The internal tube short can also take out a plate or screen resistor. So just replacing the tube will not fix this problem. The resistors also need to be replaced. You can confirm this by checking the bias for this tube. If the bias reads zero, a resistor is open.  This is an easy repair that our distributor in Australia can do.

The SE update for the REF75 comes with a complete new set of tubes including a new set of KT150s.  This is the only way it is sold. If you so choose, Our Australian distributor can also install this SE upgrade for you while the amp is in for repair.'

I then proceeded to order some more tubes to see if a replacement tube would fix the problem.

I ordered the following tubes:

2 x Electro-Harmonix 6H30Pi Gold with Matched Triodes (Balanced)

4 x KT150 Power Vacuum Tube - [Matching (10+ tubes)]

4 x KT120 Power Vacuum Tubes - [Matching (10+ tubes)]

When they arrived, I tried the new tubes but they didn’t fix the problem as the amplifier failed to switch on.  I then contacted my dealer and freighted the amplifier to Brisbane for repair.  This was done in June of last year.  I included all of the above tubes in the package in case they were needed.  I also would have liked the amp to be upgraded to SE status using the tubes supplied if possible.

In September/October last year I enquired about the status of the repair and before Christmas enquired again. After again emailing AR, I was contacted by the Australian Distributor who told me that the service agent in Brisbane had been trying to get parts for the wrong amplifier and that the amplifier would be transported to Melbourne for repair.  I asked them to get me a price for the upgrade using my tubes.

In January/February of this year, I was contacted by the Australian Distributor and had to supply proof of purchase because there was a dispute over whether the amplifier was in fact under warranty when the fault occurred.  I again asked about getting the upgrade using the supplied tubes which were still with the repair agent in Brisbane.  Eventually I was told that I could have the upgrade using AR tubes only, for the heavily discounted price of $3,000 Australian.  Nothing like gouging your customers!!!!!!  Especially when I could have bought a small car for the original cost of the amplifier in Australia.

I chose to just get the original amplifier repaired under warranty which I was told needed a new main circuit board.  This week my amplifier finally arrived back home after nearly 12 months away for a repair under warranty.  The original tubes have been put in a box with ‘Faulty Old Tubes,’ written on the box.  The tubes I sent with the amplifier have not been returned, and no replacement tubes have been included.

I am amazed that the initial fault destroyed six tubes, so I have asked how the Distributor tested the tubes to determine that they were faulty.  I am now left with an amplifier that doesn’t work and 10 expensive vacuum tubes missing somewhere in Australia.  I am also left with a conundrum, if when I finally get my tubes back and use them to ensure the amplifier works, what happens if it doesn’t.  Will AR then blame me for any fault that occurs on power up because I haven’t purchased tubes from them at their heavily marked up prices????

For me I will never touch another Audio Research product for as long as I reside on this planet.  I will be telling all my audiophile friends and putting this report on every forum that will publish it.  Best of luck for the future Audio Research and may you drown in your policy mess!!!

kalali, You realize you just did (i.e. make a hostile post to this thread) what you are criticizing others for doing?

I’ll go first. There is nothing particularly up with me, I was just advocating for letting manufacturers and dealers have a say as long as they disclose their affiliation with any equipment being discussed. I am listening to my not so uber system right now (Metheny/Mehldau Quartet, I highly recommend it). I don’t compare power cords.

Now your turn, please answer your own questions.
I think both dealer and location (i.e. closer proximity to the manufacturer) can be determining factors.  I live in Canada and with my first ARC preamp I had one of those glitchy "ghost-like" issues that would only happen once in a while.  Both the dealer, Audio Ark of Edmonton, and ARC were very supportive.  Eventually the dealer took the preamp back for full value (after two years) and ARC gave me the upgraded model for a discount. 

Now let's talk replacement tubes.  Buyers also need to be weary of some non-OEM tube suppliiers who supposedly do tube testing and matching or say that their NOS tubes came from a "good" source.  Yeah sure.  ARC is not the only component in my rack.  I have Octave MRE 220 mono's for amps.  I can tell you that manufactures design their components around a particular tube that they determine to be the best match and are reliable and can be supplied from source by the tube manufacturer.  In my experience tube rolling has never rendered a better result than original when one is dealing with a main stream high-end manufacturer whose design platform is based on tubes. 

I would not recommend getting replacement tubes from any source other than the original manufacturer for such equipment.  Sure if you have kit pre's and amp's or products from manufacturers that are intented for those who love to t-swap.

I just got replacment tubes from ARC for my Ref 10 and, yes, you pay a premium but all are perfectly matched (to the board) and marked for insertion.  Also when one of the tubes started to hum after a month, it was replaced immediately - no cost, no hassle.  That may not always be the case with non-OEM's.  Also, when you get tubes from ARC - are they ever packed well.  I got some tubes last year from a well known tube store that were thrown in a box with a bit of bubble wrap.  After three months I went back to the original tubes.
KNGHiFi,
Had you or your brother spoken with Bob directly at that time, he would've been delighted to send out free tubes. Unfortunately, with the Emotiva situation being stillborn, Bob had little to say about anything. The company never came together.

Given the circumstances, I would be delighted to provide your brother with free tubes. I'm sorry he had to go through this. Have him contact me.

Incidentally, we will be introducing an upgraded version of his amplifier in about 60 days with more power. Despite it being 25% of the price of its bigger brother, we will extend the same warranty-- 10 years amp and tubes.
Please stop with  the Carver propaganda or at least wait until my Phase Linear 700 amp quits smoldering - I am out of marsh mellows to toast.
Feel free to start a new thread about your company !
