Modern EL34s VS NOS Winged C - and return policies?


A couple questions for the tube veterans here:

1. If I buy a new set of premium tubes and they sound fine but just don’t have the magic I’m after, can I usually return them?

2. What current-production EL34 comes closest to the NOS Svetlana SED Winged C?

My setup:

• Sonore ultraRendu streamer

• Gustard R26 DAC

• PrimaLuna EVO 400 preamp

• PrimaLuna EVO 300 power amp

• PureAudioProject Trio15 Classics

I’ve rolled Tung-Sol KT150s, KT120s, Gold Lion KT88s, the stock PrimaLuna tubes, and NOS Svetlana SED Winged C EL34s. The SEDs absolutely destroy the others in soundstage and holography — it’s not subtle. I often struggle to hear big differences between DACs and streamers, but the SEDs are jaw-dropping.

I’m tempted to sell off all my other tubes and double down on EL34s, but I worry a new set might not have the same magic. I’m also willing to pay for another set that does.

Any thoughts on modern EL34 alternatives or experiences dealing with tube dealers who are sympathetic to nutcases like me? Thanks!

Besides, tubes take time to burn in and sound optimal... anywhere from 50 to 250 hours depending on the tube.
 

@pdreher This has not been my experience. Not even close. Even if it was, there are 720 hours in a month. Plenty of time to determine if the tube works for you and return it in 30 days assuming that’s what the return policy is.

new stock tubes, particularly Tung Sol KT150's take a long time to settle in... at least that has been my experience

I can't disagree with you. My only experience with Tung Sol KT150's was in an overpriced, crappy, US made integrated. It was red. Not that I'm naming names:)

The best they sounded was they day I boxed them up to trade it in.  

Conversely, the best power tubes I've owned were NOS Shuguang 6L6GC "coke bottle" (circa 1970's I believe). They did sound great as soon as they warmed up.

All fun stuff but I've simplified things with a SS amp and tube sources; DAC and phono stage that both use 12AX7's.
