Sovtek had made a decent living producing the worst sounding tubes in the industry. The surprise would be if you didn't find you're happier now with something else.
A lot of OEMs, who keep the brand in business, use Sovtek because of the pricing and their general reliability. Of course, these are not the worst as they are a KT88 - 6550s beat them in that regard.
