RAKK question

K&K Audio / Lundahl Transformers

Welcome! Need support, you got it. Or share youe ideas and experiences.

Hi Kevin
Referring to your suggestion:
'Why not use an LL1674 (1+1:4+4) in the manner of the passive transformer output stage after the DAC board to get DAC gain, do I/V and do the input phase splitting for the "rest" of the line stage circuit; and for all other inputs (like tuner, phono) switch in a different LL1674 configured for the normal 4:1+1 of Dave's line stage circuit.'
Is the reason for configuring the DAC LL1674 as a step-up purely driven by gain requirements?
I'm inclined to try the DAC board into the normal 4:1+1 of Dave's linestage and see if I have enough gain, in my system. I'd hate to go to the cost/complexity of the switchable step-up transformers, and then find I had the volume knob turned way down. Since I'm not building a standalone DAC, I don't need to meet the 2V rms output spec.
Or is there some other reason for using the 1+1:4+4 configuration after the DAC board, like impedance matching?
Many thanks
Max
