Rogue 88 problems

Well I can tell you that I spent about 1 month trying to get rid of the arc issue. I tried everything from switching out tubes to moving my components around. I finaly took the approach of cleaning up the mess of power wires in the rear. I made an effort to isolate every power cable and make sure they were all quite a distance from each other. Problem gone. I was giving up but it worked. The sound is better now also. I have since ordered a naw power cord.
I have no problem with my fan. I can only hear it if I get right down next to it.
I have had mine for 9 months and for the first time last night I put it in UL mode. Definate difference in sound. A little lean for my taste but it is there. Maybe because I have been listening it triode mode for 9 months that now I prefer that sound. Sometimes if you haven't spent time with the sound and you switch back and fourth you might not catch the difference right away. Give it some time in one mode or the other.
Next, don't listen to this guy about reliability. He appears to be one of these wannabe experts that needs to spread his opinion around. You have a very good amp, and there is not another builder around that is as nice a guy and as helpful as Mark at Rogue.

Well. I have to add this. I had my Magnum 88 for 9 months like I said earlier. I tried everything to make it sound the way I expected it to. Cables, tubes, power cords.
Well I just got my M-120 Magnums. There is an amazing difference between these 2 amps. Finaly my system sounds the way I thought it should after spending many thousands of dollars. Unbelievable, It is like I replaced the whole system. If you ever get tired of the 88, give the M-120's a try. You won't be disappointed.

Everything !! First of all, I am using a pair of Proac Studio 250 speakers. They aren't the most efficient in the world. 89db I believe. The M120's have gobs of power compared to the 88. Every note seems presented effortlessly as compared to the 88. The 88 ( after looking back at the sound as compared to the 120's) seemed strained and maybe a little congested compared to the 120's. I felt happy with the 88 for a little while. Maybey 7 or 8 months. But then I grew tired of the presentation. I am not the most electricaly technical person here so I can't explain the theory of operation but, there are 4 KT88 output tubes per channel as opposed to 2 with the 88. That has to count for something right? Not only that but, the 120's are great heat source for a cold room :-)
I felt that I couldn't go wrong. I traded my Magnum 88 and $900 for the pair of 120's and I haven't been happier.

I run in triode. I prefer it over ultralinear

Without question the 120's will provide those qualities and more over the 88. I had the Magnum 88, and now the Magnum M120's. Just leaps and bounds above the 88. I also use the Magnum 99 preamp. I wasn't thrilled with the 99 matched up with the 88. I knew I spent a lot of money. I new I was running tubes. I knew I was running in triode. I just wasn't wowed. I was also going to sell my 99. After I hooked up the M120's, the 99 sings. I love the combination. I traded my 88 and $900 for the demo pair of 120's. No looking back or any regrets.
