Doug,
It appears that the upgrade from Level B to Level C involves not only the addition of the output transformers, but also a new analog board based on the 5687 tube (Level B analog stage designed around the 6922 tube). The 33:1 output transformers made by Audio Note are not listed as being compatable with the 6922. Therefore, upgrading the analog board is also required.
A cost comparison of the options being discussed suggests that going directly to the Level C kit is the most cost effective and hassle-free approach.
Cost of the Level B Signature kit: $2000.
Cost to upgrade to Level C Standard: $475
Total: $2475.
Cost of the Level C Standard kit: $2100.
Total: $2100
If you plan on going to Level C Signature then the cost breakdown is as follows:
Level B Standard kit: $1700
Cost for a parts upgrade to the Level C Signature: $675.
Total Cost: $2375.
Cost of Level C Signature kit: $2400
The costs are much closer in this case, but their is more work involved going from the Level B Standard to the Level C Signature (build and install the Level B board, then take the Level B board out and install the Level C board and output transformers).
I am sure a person would WAY not be 'slumming' with the Level B Signature. It's a fine DAC in its own right.
Regards,
Bob
