Carver Raven 350 Amps

erichgs,

Well its nice to know that we both hear the same noise (hiss).
Bob Carver doesn’t really believe me. He thinks there is something wrong with the DEQX.
Oh well, at least with using the RCA outs on the DEQX to the Carver it is dead quite.

BTW, have you mastered the DEQX?

If by mastered you mean have it hooked up, then yes I have mastered the DEQX.

Swapped the Telefunken ECC801s pair in for the stock 12AT7s.  The improvement is larger than when I swapped the Telefunken ECC83 pair in for the stock 12AX7s.  Really happy with the sound improvements from these changes.

erichgs,

There are a lot of settings in the DEQX and it can be difficult to master. The instructions make you jump back and forth. I was just wonderin’ if you have it figured out yet. I have found that my main DIY speakers sound best without any DEQX adjustments but the sub crossover, delay and mixing with the main is valuable.

On the tubes, is it the sum of both of the Telefunken tubes or is one slot better than the other?

ozzy

I haven't tried swapping the stock 12AX7s back in, but I would have to imagine it is the sum of both.  Also, the improvement for the ECC801s was very noticeable in the highs which was too bright before.   The ECC801s did a lot more to mellow that than the ECC83 did.
