300B or 2a3 SET Class A for Heretic Model A?

I can recommend:

1. 300B integrated Allnic T-1500. I listened to it in Montreal Audio show and it sounds really great. It has 6sn7 driver loaded on choke - LC coupling.

2. Aric Audio Super 300B. It should be even better because it has 6v6 powerful driver tube with inter-stage transformer. That is very important for difficult to drive 300B.

3. Coincident Audio Frankenstein - mono blocks. It is also has inter-stage transformer and powerful driver tubes. I listened to this amp in my friend's system.

Hi @pdreher ,

What is a size of your room?

In room smaller than 250 sq. feet 300B amp should be enough. I had opposite experience with McIntosh MC 30 and DIY 300B amp with my Altec 604E. But the room was small and probably 604E is a little bit more easy to drive versus model 19.

But I liked a lot MC 30 with Spendor 2/3 in the same room.
