Bottom Line:   
I have owned my Baron 5881 for over two years. In this period I have never had any problem with this stock amp. I have not even changed a single tube. The only maintenance neeeded is adjusting the bias and balance which is so easy and troubleless.

The biggest advantage of this amp which overwhelms any other amp available is the flexibility. You can adjust it to play any kind of music, even with the unit turned on. I prefer to listen rock with one pentode per channel on, one feedback and the rest in triode. Classic and jazz is incredible with all triode and no feedback since it just puts you together with the musicians. The more wattage you put (more pentode), the further back you are put. I think that the full power (160 Wats) puts the listener in the far back rows, which I do not like.

As for the quality of the music produced by this giant I must say that I just love it. Clear, solid or intimate when necessary. I simply stopped looking for other amps and do not inted to change it for any other, unless it be another updated Baron.

Since i live in Costa Rica I do not know how good is the service, anyway, I have not needed it.

I use this Baron with a pair of Sonus Faber Extrema and no preamplifier. Good cables and interconnects are indispensable conditions to achive a good sound. Believe it or not I use a pair of affordable Apature silver cables combined with Spectral 500 interconncts with excelent results.

Bottom Line:   
options in setting negative feed back and triode/pentode mode make initial set up time consuming but rewarding. i'm powering paragon jubilee/jems which are dynaudio speaker based systems and i found the best setting at 1 triode/2pentode with a 2 stage negative feed back. (this coincides by accident with randys recommended setting.)i have rolled tubes but ended up using mesas 5881s and yugo's for 12ax7a. this gives me a very neutral stage for very different sources, i.e. bat d5 cd player, cal audio alpha/delta cd, and and oracle/mit/glider turntable. each is very involving in its unique way. bat for orchestral, cal for jazz an vocal. very detailed and very involving. if i want to read i hook up the sf80. this amp isn't an answer to solid state problems for those who want solid state, nor is it a warmish tube amp which will solve problems of speakers with bright high ends (or upper mid-range), but with the right speakers it can be a good foundation for the rest of your system.

Bottom Line:   
Man are you guys serious about this product. It is a love it hate it unit. Very industrial which I like. Very well built. Great service when it was time to replace original tubes. Some have indicated problems. I found Mesa folks polite and helpfull. The bass is very good but not great. Very tight and clean but not in the best of solid state class. The more triode you dial in and the less NF you use and of course the bass will become weaker. Full triode is not where you set this amp for PF Dark side of the moon. Full pentode should not be used on Natalie Cole. This amp is for someone that likes to get involved with their system and when set correctly it is quite good.

I won't get into associated equipment. It does not matter with the Barron. You can make it sound like whatever will float your boat.

Problem with a product like this is the stupid factor. If you are not a tweeker buy a good push pull tube unit and enjoy the music. Even for a tweeker the Barron can at times drive you nuts.

This amp has great value for the money. It is industrial however. If you like lots of chrome, inch thick faceplates and rosewood trim buy something that will make you happy. It will cost a bit more but we only go around once.

Some of the best sound I have recently heard was this amp Cal audio Alpha/Delta CD and a MFA A3 preamp through a pair of classic Klipsch speakers. The full triode of the Barron made those horns sing on some old Mel cuts from the 50's. When more pentoid was used the results were not nearly as good. Those old Klipsch and Altec horns were used to Mix the old 50's vocal stuff and they still sound pretty good. It was fun anyway.

Bottom line to all this is keep it friendly. It's all about having fun.
