Aric Audio 300B SET Monoblocks

Hey mac48025,

Congrats!  Aric builds beautiful sounding equipment and I know you and he went " full monty" on your pair of amps.  

Thanks for putting this up Tom! Also thanks for the kind words @teajay ! I’m stoked that Tom is enjoying these monoblocks as much as I was for the several days I had them running. I have never heard that kind of speed, purity and control over the bass as well as extended highs from a 300B. This is really a combination of all of the upgrades we decided upon, but the weight of this voicing is due to the C3M driver. The C3M is an extremely linear tube, and has the current and voltage needed to over-come the 300B’s Miller Factor and also to push it’s grid when the grid becomes positive (both of these things are what are typically associated with the common "rolled off" highs or "wooly bass" people here from most 300B amps). The 300B and most DHT’s are all capable of extended frequency response on both extremes- provided the driver can avoid slewing. On the tech side of things, some of the other upgrades not mentioned in the original post include (but are not limited to): A full film capacitor power supply. Hexfred diodes in a hybrid rectifier circuit (what this does is runs a tube rectifier in parallel with the ultra-fast diodes so that there are no switching pauses in the rectification and virtually no voltage drop (common with tube rectifiers)). A low impedance power supply using a very low DCR choke for fast rise/decay times and no over-hang or bloat. Schottky diodes for the well-filtered 300B DC filament supply employing a choke. Tube damper plates which de-couple the C3M’s socket from the chassis. All film-capacitors used for cathode bypass. In fact there are no electrolytic capacitors in the signal path in any way, shape or form. This includes the power supply as the power supply IS directly in the signal path. Also, this amp is DEAD QUIET- meaning no tube rush, buzz, hum, etc. is present even with your ears right up to the speakers. With these "all out mods" and the 4 chassis design we employed (with umbilical cables), the price is $11,900 for this build (tubes included).

Hi Tom,
Congratulations  on acquiring the custom built 4 chassis SET mono blocks. I'm glad to read that you're so happy with them. I have no doubts that these are outstanding in their sound quality.  An all out design/effort from Aric Audio . Terrific upgrade choices/decisions by you.and Aric.

Tom they sound like amazing amps and I am sure they sound fantastic. And congrats to Aric on a great build with premium parts! I am sure they sound amazing and you will enjoy them for many years to come.
