Does anyone run Vak 330-340V for 2A3/6B4G ?

The output power is 4W. 2A3 is a direct heated triode, but unlike 300B, the sound of 2A3 is more transparent, dynamic and fast...

What is the price of this integrated amp?

Hello,

The new price for the 2A3 single end integrated amp is USD750+shipping cost. The price included high quality tubes such as Psvane 2A3B, GE 6SN7GT and GE 5U4GB rectifier.

Thanks,
Tony.

OK...I have a few more questions. Does this amp sound better than a 300B tubed amp? Do you offer an Integrated 300B amp?

I see you also sell speaker kits. Are the prices for the kits just for the cabinets? Are the speakers efficient enough for the amps?

Right now I have 88db at 1 watt speakers. They probably are not the best for the either the 300B or 2A3 amps right?

Thank you,

Blake

Just asking...has anyone else purchased these amps? They certainly look nice. And with them being integrated it sure saves with trouble of needing a preamp, interconnects, etc...

Do these amps sound good and is the build quality good too?

And how are the speakers....Musik007...pardon me for asking other forum members...but I'd like the opinions of other customers. I really am looking for something that sounds cleaner than my Dynaco PP amp.

Thank you,

Blake

Hi Blake,

As 2A3 ad 300B are different on their sound characters, it is very difficult to justify which one is better on sound performance. Depends on personal tastes, someone like 2A3 and someone like 300B. Basically, 300B is more powerful than 2A3 on technical specification. The output power of 300B class A single end is 6-8W and 2A3 class A single end is 3.5-4W. I also offer integrated 300B amp.

The price of speaker kit includes drive units, cabinets, binding posts, connection wires and acoustic materials. As they are full range drive units such as Markaudio and Fostex and no cross over needed, both 2A3 and 300B amps can drive those speakers well.

If the speakers at 88dB are two-way speakers with crossover, there is no problem for 300B or 2A3 amps to work with. If you like to listen orchestra, 300B amp would be able to perform wider and deeper sound stage and smoothness than 2A3 amp.

Thanks,
Tony.
