ARC Quality Issues Ref75 Ref5SE Ref10


Over the past two years I had several issues with ARC Ref gear and am wondering if I'm the only one out there having so much "bad luck"?

My issues started when I bought a Ref5SE plus Ref75.
The two meters in the Ref75 had a noticeable different color and had to be replaced by my dealer.

Two of the Ref5SE tube sockets were soldered crooked to the board. I found a loose screw bouncing around inside the chassis when I unpacked it and found that the two crooked tube sockets were not even bolted down to the metal support on the main board. ARC apologized and replaced the brand new Ref5SE.

The replacement Ref5SE blew up after 600 hrs of use. A small component in the power section exploded with a single loud bang with smoke following.

To not end up with a nearly new but repaired preamp I upgraded to Ref10. The Ref10 power section also blew up after two months and only 390 hrs of use. One or more of the smaller white caps in the power section exploded (four or five significant and loud bangs with smoke). My dealer just informed me that ARC is going to replace the failed Ref10 against a brand new one.

I can not believe I am the only one having repeated problems with ARC's new gear!?

Feedback and comments will be greatly appreciated !

Aisip, the Ref75 is a wonderful amp. Besides the power meters I had no problem with it so far (appr 1800 hrs). If your speakers have a decent efficiency and are not too hard to drive the Ref75 will impress you (I use Coincident Pure Reference speakers). It combines many positive attributes and simply gets out of the way. The Ref5SE was much better than the Ref3 I owned as well - but the Ref10 is simply in a class of it's own (as long as it works ;-)). I just hope the replacement Ref10 (expected to arrive on Tuesday) does not blow up on me again - because I don't see me looking for another preamp anytime soon.
Feel free to email me if you have more questions about sonic performance.
I don' use power conditioner but have dedicated power for each device. I can hardly imagine that the usual power swings of a few Volt are able to blow up capacitors ...?

In regards to ARC's QC card - how can a preamp pass a thorough QC check with twoo loose and crooked tube sockets - plus be boxed up with a loose srew bouncing around inside the preamp? The QC card is a piece of paper - and has NO value if the people who sign it don't live and breathe Quality ...
Thanks to all for your responses on this subject. It seems we share both - good and not so good experience with ARC gear. So far ARC and especially my ARC dealer have reacted very quick and obliging. I hope ARC simply had a bad run of components and gets the problem under control.
What seems obvious though is that cost savings at ARC are more important today than a few years ago. While the Ref3 was double-boxed at it's time - Ref5SE and even Ref10 are shipped single boxed - held together with one layer of paper tape. I believe this is the wrong place to save money when shipping sensitive and quite expensive audio gear. Esoteric for example even triple boxes their gear. I like that!
@Bifwynne,
You are not alone. A couple of weeks back I began to sense a slight imbalance between channels, lo and behold, V5 was down to 61mA , V7 On spec, V9 ON spec, V11 down to 62mA.
V5 biased back to spec and remained as such over the next couple of days, on the other hand I could not manage to persuade V11 to re bias beyond 63mA. Substituting with KT150/V7 indicated A problem with the bias circuit to V11 as that valve promptly dropped 5mA.
I advised my dealer of the problem and as I am still under warranty collection was organised PDQ.
The snake in this tale will see me without the Ref150 until after the Holidays. The ladder? Well that has manifest in the form of the Distributers own GS150 in situ For the duration!
Unfortunately, the GS has just the 60 hours on the clock, and whilst hinting of great promise, is still quite 'tight' ergo déjà veu with break in on the Ref150, however I am hoping to rack up enough hours on the GS in order to make some sort of valid comparison.
