Aric Audio Super 2A3 SET


It just arrived just about a week ago, but I feel inclined to write a few words about it since my level of satisfaction with this amplifier is immense. I have nothing but praise to give in regards to the level of customer service I have received starting with a curious inquiry to having the amplifier in my home. Since I'm no expert in the world of tubes, I had quite a few questions.

It started with me asking about the 2A3 amplifier listed on his webpage and Aric got back to me with a suggestion. He said he had been waiting for the next order of a 2A3 amplifier and was eager to revise the product and put some new ideas and upgrades into it.
Me being a novice only understood half of the improvements he listed, but it all sounded good to me. I told him about the 2A3 amplifier that got me into looking at a 2A3 based amp and he was very familiar with the one in question and described in detail what he would do to make his version "better". I was sold, and I pulled the trigger, and oh so happy I am that I did.

It is a dual-chassis design that has an all film-capacitor power supply with toroidal filament transformers, DC filaments using Schottky diodes, and film cathode bypass capacitors. Audyn "true copper" foil coupling caps and a choke-filtered power supply, Vishay wire-wound resistors used throughout. 6SL7 SRPP driver stage and 2A3 single-ended output stage producing 3.5 watts per channel into 8 or 16 ohms. I'm running it with the supplied rectifier tube (CBS 5U4GB) and a pair of NOS Tung-Sol 6SU7GTY "Super 6SL7" and a pair of PSVANE WR2A3.

The amp from Aric replaced my old trusty Audio Space Galaxy 88 that produced 48 wpc in ultralinear and 24 wpc in triode. My first impression was that this feels like way more power! at only 3.5 wpc. The bass is deep, tight and "meaty", I hear midbass like I never did before. It's so clear and well defined and when I turn the volume up my walls are shaking, with 3.5 watts(!). Vocals sound like they are floating around the room and with an acoustic guitar I'm just there in front of the stage. It has speed and a level of transparency that is on a completely different level compared to my old amplifier. It also has a completely dead black background.

This amplifier just plays in another league compared to my previous one. I can only recall from memory another comparison of a much more expansive 2A3 SET that got me interested in the first place, I heard it for a lengthy session at a friend of a friends house and it blew me away. This amplifier beats it if my memory serves me right.

I can't imagine a better amplifier at this price and I could use a bunch of more superlatives to describe it.
My current speakers are a pair of Zu omen plugged in on the 16 ohm taps and it seems for now to be a match made in heaven.

Congrats tby,

I have had the great pleasure to review numerous pieces of Aric's and they have all been superlative music makers.  I'm sure your two piece 2A3 SET is a honey of an amp!  Aric is a great designer and builds reference level gear, regardless of the price.  On top of that he's great person.
@tby,

Congratulations on your purchase! I can relate to your experience having switched from Audio Space Reference 3 (805) mono’s to Aric’s Super 300B mono’s. Your amp is only going to get better, wait till you hit 200 and 300 hours mark. What preamp you’re using with 2A3’s amps?

You may read about my 300B project with Aric here once you hit toggle details under Components.

Aric is super knowledgeable and his expertise in building/designing tube electronics is exemplary.
Enjoy!
Congrats tby!I'm a very happy Aric Audio customer also.Enjoy!
Congratulations on your new amp! The 2A3 tube is one of my favorites I love the detail and clarity you get while still retaining SET warmth. Enjoy!
Thanks for all the kind replies!


@teajay your mentions of Aric’s gear is actually how I found him in the first place. :-)

@lalitk Thanks! Interesting to hear you also switched from Audio Space. Sounds very intriguing that it will only get better from here. Amazing system btw! I am using a passive preamp called icOn4. I made an attempt of adding my office system where I use the amp to the systems page where you can find a link to it here: https://systems.audiogon.com/systems/8714

@jtcf Thanks, happy to hear that. Checked out your system it looks great!
