KR 300Bs...I'm confused.

SET Asylum

Single Ended Triodes (SETs), the ultimate tube lovers dream.

KR currently lists on their site two 300Bs and one 300BXLS.

Ignoring the latter, higher-power tube, the only difference between the first two appears to be the bottle shape.

Tube Depot, the official US importer of KR tubes, sells the 'Coke-bottle'-shaped version for $925/pr. delivered.

Some straighter-bottled version is listed on eBay...

...for $1950 (!!!!!!!!!!!!!!) per pair BuyItNow price.

The pics reveal some apparent construction differences between these two, but it could be just the pics.

The sounds of the KRs seem to be well-liked here, and I'm considering a pair for my Coincident Frankenstein IIs.

Any thoughts on the differences between these 2 KR 300Bs?

FWIW, I now have the following 300B pairs:
1. Original Shuguang Treasures,
2. Gold Lions, purchased new,
3. JJs, used, 'nearly new',
4. Sophia Golden Princesses, used with maybe 100 hours, and
5. Psvane TIIs, new, from Grant.
...so I surely don't need more, but, of course, what does 'need' ever have anything to do with this wacko obsession of ours?
