We are long term Audiophiles some 50+ years, and we are somewhat new to tube rolling.

We've owned 3 different types of 300b tubes:
Western Electric 300b for about two years at $1,499
Wathern CryoTone 300b (in a complete set) since August 2023 at $1,196 for the 300B tubes
The new Decware 300b Tubes for 2 days for $299

Each 300b tube is fantastic in its own right, we are Restaurateurs so let us give you a food comparison. There is ice cream you can buy, and there is super premium ice cream that is a much better product than inexpensively made ice cream. One might like vanilla bean, one might like chocolate, and one might like strawberry. They are all better than the lower quality tubes, but one couldn't tell someone else what they should like.

These tubes are like that, all we can say is the Decware 300b @ $299 represents a fantastic bargain for a super premium tube. We've only had it for two days, but it sounds real good so far!

"These tubes are like that, all we can say is the Decware 300b @ $299 represents a fantastic bargain for a super premium tube."

I have a pair as backup of Linlai 300B tubes that were inexpensive and surprisingly nice sounding--so I don't have any doubt that the Decware version would sound great.

Everything we've bought from Steve at Decware has improved our system  300b Amp, Zbit, ZRock II, all of our cables, all of our plugs, and the Decware Reference Speaker Cable ZSTYX.

We feel everything we bought is of the highest quality at a very reasonable price, you just have to be patient. We waited 2 years and 2 months for our Sarah 300b amp and after having it for a little over a month... we would do it again!

Now that being said, the ZRock II really is great, everytime we roll tubes we just tweek it a bit and the super premium tubes get even harder to tell the difference between them.
