It's been about a month now, that I started listening to the Psvanes. I don't want to make it sound like they are x or y or z. But the fact is that they have not diminished my listening experience. And I am happy that I can choose to listen to my beloved Mazdas at some later point in time. And I got the Psvanes for $55. These are much neutral than the ART series. The bass is well defined on these tubes. I am going to guess that some folks will take this as "less bass". But I really don't think so.
One negative experience about the previous ART series for me was they lasted just 9-10 months before getting noisy. So keeping fingers crossed, since these cost even less. Hope they last at least 10 months, which will be about $5.50 per month for auditioning these tubes :-(
