Current Best Value In A Pair of Quality 300B's?

The Psvane Acme WE300B are in the middle of the price range and highly regarded by many. Probably the best bet in your price range.

If it was me, I'd spend an extra $300 on the US made WE300B.

Western Electric 300B Pair

I haven't heard either but have read that the US made WE300Bs sound slightly better. In addition, unlike all others, they come with a five year warranty, something I value.

I did have a pair of Kansas made 300Bs many years ago and they sounded fabulous in my application.

Thanks for the recommendation for the Electro Harmonix. There clearly appears to be  a large gap in pricing between the handmade and machine made. And nothing, really, in the middle. 

I've seen a few comments that the Cossors, which are very affordable, may outclass the other machine made tubes? Does anyone have any thoughts on that? A forum member here said they were clearly better than the Gold Lions, and several others. 

There is a break between handmade and machine made.  So it is in essence Inexpensive Russian, Chinese and Czech (JJ) vs much more expensive hand made tubes like KR, EML, Elrog, etc…

the best value at the low end is probably the Electro Harmonix 300B.  These are not cheap and will give you a good idea of what a 300B will do in your amp.  

I would expect Tube Depot to have these in-stock.  

I appreciate everyone's perspective. However, as I noted before, once I have tried a pair of 300B's in my DAC and IF they provide the sound I want, I'll willingly pay $1000, or a bit more for a pair. However, initially, when I am simply trying them out,  I'm not interested in spending anywhere near that much. Everything that's been mentioned has been in the $1000.00 per pair and up pricing. 

There must be some solid values for less money? 

I finished building a pair of 300B parallel SET monoblocks a few weeks ago. I started with a set of relatively inexpensive Linlai tubes but decided I wanted to really hear what these amps are capable of so I ordered a matched quad set of Western Electric tubes.

I’ve only had them installed for a week, but fresh out of the box, there was no comparison to the cheap tubes. Way more detail and mid-range sweetness. Vocals, guitar, sax, and jazz trumpets sound fabulous.

I have no regrets for the expensive purchase and can’t wait to hear how these sound after a few hundred hours.

I just ordered WE 300b also.....   im having a 300b built , so why not?

I recently upgraded to Psvane Acme from Shuguang Black Treasure in my custom built 300B monoblock amps. Acme in different league from Shuguang. Much higher resolving and far more natural timbre. Haven't tried any other premium 300b up to this point, but based on my research and observations of 300B's, I don't think you can go wrong on any of the boutique 300's. Slightly different flavors, all will resolve and have refinement you won't find in lower priced 300.

For me it was sort of like throwing darts, whatever came up winner I chose. If reliability paramount, EML XLS and WE only 300B's I''ve yet to see any failures with. The Acmes are really extremely nice tubes, aprox. 75 hours and getting better!

When i got my Eddie Current Studio B amp, I got Gold Lion 300B's for them. I'd been recommended the JJ's, but they were out of stock everywhere at that point.  When they came back in, I did get the JJ's for about the same price, and they were an improvement, but I wanted to hear my amp as best as it can be, so I forked out $1400 for a pair of new US-made Western Electric 300B's - still breaking them in, but so far they are wonderful - in another league than the previous ones I'd been using, better in every aspect, as you'd expect. If you want to spend time researching, you could probably find some that were less expensive and just as good, or maybe even better, but I decided to skip all that and just go for the WE's.
