    The cable cooker uses a 12V DC power supply and no transformers - this means that output voltage will be less than 6Vpp - the cold tubes will happily ignore them.

    However, the REF6 has a lot of other capacitors that also must be burn-in, such as plenty of decoupling capacitors. And part of burn-in is applying the 90V DC or more to the capacitors - this only happens when the preamplifier is on! Do not connect the cable cooker without taking the power cable from the connector, sometimes a mains transient can switch the preamplifier on!

    Has anyone heard the Coincident Statement Linestage compared to
    the Ref 6 ?

    I just placed an order for a Pass Labs 250.8 to
    go with the Ref 6

    My question is if my DAC is single ended going into the
    Ref 6 is it going to really matter if I use the SE or BAL
    out to the Pass Labs ?

    You will still benefit running balanced from your preamp to amp.

    Summary: Yes, the REF6 is deriving an inverted “leg” out of the single-ended signal and thereby converting it to balanced. That is why the balanced output from your REF6 is 6dB higher than the single-ended output. Truly balanced products should sound better when run balanced. Your Pass Labs amp should sound better run balanced rather than single-ended.

    Over the weekend, I swapped out the svetlana wing C 6550 with a KT88 in the ref 6. Initial impressions was a tighter bass, slight improvement in soundstaging and a faster more at ease presentation. Highs was abit more refined as well. However I do find that it lost out very marginally in bass extension.
