Considering switching from Audio Research to PrimaLuna, troube with VS115 amp


Hello everyone, I have question that I hope some of you either can answer or have an opinion on. Ever since I was 17, I have always wanted to own Audio Research equipment. I’m 56 now, and finally was able to fulfill my life long dream. My first acquisition was an ARC LS15 pre-amp bought here used in mint condition. I paired it with a Vincent 331MK hybrid amp also bought here used in mint condition. The resulting sound was impressive. After that, I started looking for an ARC amp I could afford. The resulting search found me an ARC VS115 amp also here in used, awesome condition. This is where my problems and my doubts started. Upon hooking up the amp to my system, a tube in the left channel arced and blew a resistor. I had to take the amp to an ARC dealer and he installed a new resistor and suggested I buy all new tubes from ARC for the amp. I did and when I got back home, I again hooked up the amp and immediately upon turning the amp on, I started to hear thumping sounds coming from my left speaker, then, two left channel output tubes started to glow a very bright orange, and then white smoke started to rise from one of the tube sockets. I immediately turned the amp off. I called the dealer and he suggested I mail the unit back to ARC. I did and I am now waiting to see what they say.

During this time, I started to search out other brands and came across one called PrimaLuna. I have watched their videos and seen them compared to ARC equipment. Their build quality seems to be superior to ARC and the reviews are over the top. I am looking at their Dialogue Premium HP amp and their Dialogue Premium pre-amp. For what they cost, considering how they are built and supposedly sound compared to units costing 3 to 4 times their price, they almost seem too good to be true. Anyway, my bubble has been burst, and in simple terms, I am considering jumping ship and going with another company instead of ARC, despite all those years of drooling and waiting.

My main question is this, is there anyone out there that either owns PrimaLuna or has had experience with the equipment and can give me their opinion on owning and using it. Then, my second question is how does PrimaLuna really compare to other high end equipment such as ARC. Kevin Deal in his videos on PrimaLuna makes a very compelling case for the equipment. In one video, he compares an ARC LS17SE to the PrimaLuna pre-amp.

My last question is in regards to my ARC VS115 amp problems. Anyone have an opinion on what is going on with my amp or a VS115 in general. For those of you who want to know what else is in my system, I am using KEF 104ab speakers, a Cambridge Azur 752BD Blu-ray player as my CD player, Morrow Audio Cables and I am considering getting the Sony HAP-Z1ES music player for my digital files.

I greatly appreciate all who take the time to comment and give their opinions. I will be glad to answer any questions you may ask or provide additional. Thanks for your help. Steve.

would agree with Pokey. Have 4 PL amps, as well as numerous copies of tube amps from other mfgrs.

The PLs sound good right out of the box, and as Kevin noted, all point to point wiring which you do not get with most of the US mfgrs. who use circuit boards to save on labor costs)

The PL amps offer a great starting point to cap upgrading tube rolling etc.
And the PL amps don't run the tubes right at the design limits so you are not replacing tubes every 6-12  months with a PL amp.




I am far from an expert. When I was looking for an amplifier, I noticed that compared to the number of units sold, there are few used PL amplifiers out there.
Between that and discussion with Upscale Audio I took a plunge and got a Dialogue HP integrated.
I got the KT150 from the start.
I could not be happier.

Guy, great forum.  New to the industry, however my 85 year old dad is a veteran playing reel to reel parties in his day.  His biggest complaint is that what he paid 250.00 for in his day is now 5k to 8k.  That is a lot of inflation.  Saying technology of the old day still relevant today.  I like everyone wants to upgrade to a retirement system.  With my Tannoy Turnberry GF and my Delphi-Oracle MKVI turntable maxed out with a HANA ML MC I too want the best sound and money value for my tube amp upgrade.  Have the Cronus Magnum ii and have eliminated all thumping, humming, etc by moving my WiFi to different location.  Volume all the way up, NO distortion!  So in the spirit of finding my best integrated tube amp, I ran into Raven on the net and they offer a Free 45 day trial with no questions asked.  If you don’t like you spend 40.00 to ship it back.  Wish more people would offer this.  In defense I do have a high end audio store around 30 miles away but they too only sell limited brands based on the market interests and their ability to invest.  I will check out all the other brand mentioned and thanks for the honesty.  In defense of Kevin (I live in New Orleans) who else spends the time to make these informational videos that are a great resource for education and information.  The TANNOY speakers I purchased are a wonder upgrade from my Golden Ear Triton 2.  The sound gets my heart into the music and I dance to that sound, a lot.  Thanks Kevin, you give us a great bench mark no matter what we decide on....
