JJ 300 B tubes or others ?

Hi Reb,
I will agree with Swampy. I started out with the same tubes as you in my kit, and the Black Treasures would be hard to beat at that price. I put in the originals just for the heck of it recently, and they sounded anemic by comparison. Less body, and thinner bass notes, plus more of a feeling of left, right, center, as opposed to a more filled-in wall of sound.
I know from Charles and others that the higher end tubes like Tataksuki and others are considerably better, but again, at this price, it's a great upgrade.

Swampwalker and Roxy, thanks for that tip. I'll price those out!

I agree, the Black Treasures would be hard to beat at that price. I own a pair in addition to many others.

Pretty much any tube that replaces the JJ will be an improvement. I was very unimpressed with JJ300B tubes. The Shuguang BT represent the best value for the $ right now and are well made, unlike the JJ.

Rebbi,
At your stated price point you won't do better than the Black Treasure tubes(BT) IMO. When the BT was first available for sale they were 600.00 per pair from Grant Fidelity. Given their performance at that time(2009) they were worth it relative to the 300b market then. They sound very good and are quite reliable with very good construction. The JJ is in a lower tier.
