Hm maybe a mismatch in the components.
I owned a 34,44, the complete 22 System and in the living room is a 66/67/606 System working.
I always liked the 34 and I owned a Rowland Consonance II at that time, too.
I used it with Quad 22 tubes, but for these I had to replace a resistor for higher gain. Quad service did that. It sounded also very good with the 606 amps. I think, there is something in your System which makes this dissapointing result.
