Carver Raven 350 Amps

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?

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.

I am just using the cords that came with the amplifiers. No issues, so no reason to change

I bet replacing stock PC will yield bigger improvement over tube rolling.

FYI, there are 2 types of Telefunken 12XXX tubes, ribbed and smooth plates.  ribbed plate is more neutral with higher resolution.  I always prefer ribbed plates.

has anyone try PSVANE tubes in their 350

To those that own these amps, I just installed a couple of the SR Blue fuses in them and it really adds to the smoothness of the soundstage.
Highly recommended.
