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!!!

Sounds like your problem is with ARC dealer in Australia.  An Ayre MXR-20 owner in Australia is having similar issues so these are the brands to avoid in Australia.

When a power tube blows, bias resistors were blown and need to be fixed.  ARC told you ... so why did you use the amp with a new tube without fixing the resistors?   Tube probably ran too hot and caused more problems.   If this is the case, then it's your fault.
The resistors are visible so if blown, why bother trying a tube?

It appears the problem is with his Australian dealer.   I always try to buy from manufacturers in my country to avoid these types of issues.

knghifi, this thread is irrelevant to you. But to someone that may have thought of buying a new ARC amp, the fact that the company is so rigid that you have to buy tubes from them for a warranty repair is a non starter. Especially since it is well documented their tubes sell at rip off prices. I know, you get what you pay for, yada yada.
It's obvious reading your posts you don't have any personal experience with ARC in NA so not going bother.

Is it also part of their policy to keep the customer's tubes?
I have no plans moving to Australia but for educational purposes, why don't you contact the Australian Distributor and let us know.

This thread is IRRELEVANT if living in North America.  ARC service is 2nd to none!
In the USA if you send in an amp or preamp to ARC they replace all tubes with ARC tubes before they fix the amp. They send back the non ARC tubes.

Remind me never to buy ARC.  While there may be some justification for charging more for tubes due to their testing process, there is no justification for requiring the purchase of a completely new tube set in order to get a warranty repair done.  None.  Full stop.  Imagine if the fuel pump burned out while your car was under warranty and they told you you had to buy four new tires, new wiper blades, an oil change, and brake pads to bring it back to factory new condition in order to get it fixed?  Tubes are a consumable.  That policy is nonsense.
Not 100% accurate.   They test the tubes and inform you the number that doesn't meet spec before replacing them.

I also have a friend negotiated with ARC in purchasing tubes from Upscale and ship them to ARC.  All these rules are negotiable case by case. 
 According to my information, your unit is out of warranty and was damaged by corrosion caused most likely by a fluid being spilled onto the main board.
Since the unit is USED, is it possible previous ownerS spilled fluid in the amp?
AR did NOT say they would do the upgrade with your supplied tubes. To draw an analogy to automotive repair, reach your own conclusion that they should is YOUR problem, not theirs.
SE is ARC transition to KT150.  The SE upgrade includes a complete set of ARC tubes and I believe a fresh warranty.   Another words, you can't get the upgrade without the tubes. 

Also warranty is not transferable so don't understand why you believe it's a warranty repair since it's used? 

Your initial problem sounds like replacing 2 or 3 $5 resistors so don't understand how it escalated to replacing board.

OP doesn't understand how the amps works, company policies ... I suggests do some homework before your next purchase so you don't blame the company for your ignorance.
This is slowly making sense. Tube arc and took out 2 to 3 $5 resistors. Technician opened the amp, found corrosion from spilled fluid and also wants to replace the board. It's an USED amp but OP never considered the possibility past ownerS spilled fluid in the amp.  
OP blames ARC ... blah! blah! ... ARC haters piling on drawing conclusions failed tube caused board failure ... over price, rip off, point to point wiring ... blah! blah! ...

I feel vindicated!

I bet this is a typical ARC bitching thread.
I bought the amp second hand from a guy in the US when the Aussie Dollar was higher.
thazeldean, I guess you meant preamp?
@jea48 

Thanks for all the posts guys but some information to clear up some misconceptions. Firstly the amp failed with the original tubes. I could not see a resistor blown when I opened the amp to see what had happened. I replaced the fuse in the amp and tried other tubes but the amp wouldn't power up so I couldn't have damaged it by trying new tubes. I was accused of pouring water into the amp by the Brisbane repair agent etc. etc. etc.

Compare this to my experience with Allnic. I have an Allnic L-3000 that was upgraded to L-4000 by the manufacturer. I bought the amp second hand from a guy in the US when the Aussie Dollar was higher. I left the batteries in the remote for too long and they leaked and wrecked the remote. By the way the preamp has worked faultlessly since I purchased it second hand in 2011 and it is the best sounding preamp I have had in my system.

"I bought the amp second hand from a guy in the US when the Aussie Dollar was higher. ..."  After OP mentioned amp is bought new, I reread and think he meant "preamp second hand ..." and not his REF75.

I can't imagine a company owner promoting his products in an open forum by trashing another company.  Wow!   Who's next?

Current Carver products are very good.  My brother bought a 'Black Magic' VTA 20S Tube Amplifier for his Avantgarde.  ~100 hours 2 power tubes arc and took out fuses.   Carver was in middle of Emotiva so no luck getting power tube replacements under warranty but overall he's happy with the amp.

fmalitz, you're doing disservice to Carver with your actions.  
It’s no longer unusual for a high-end company to be sold. As fmalitz has pointed out, many big names have been sold multiple times.
tomcy6, You are making clearthink point. Life time warranty is only as good as company in business.

My brother got caught in one Carver’s reincarnations. He understands business and nature of tubes so did whine and whine and just bought replacement tubes.

So please lighten up. With 14 posts to your name, it might be a good idea, to lurk for a while until you get a feel for what is helpful and what isn’t.
Curious, how do you formulate length of lurking by post count?  Did you steal one of Almarg's slide rulers?
