Musicophile;
My eperience ( my system ) with the SED Cryo'd El34 is that they do not sound the same ( or as good ) as the stock SED El34..Point being they sound warmer ( quite a bit ) and not quite as much air..If you need more warmth,thats a different story,but if you systems tone is where you want it, the Cryo'd El34 would not worth the extra fee.. Some tubes do sound better after Cryo treatment but my experiance the SED El 34 isn't one of them..Keep in mind this is to my ears and my system..
System:
Thor Audio T1000mk2 Linestage W/Mundorf Cap Upgrade.
