How are Mullards supposed to sound?


System: Rogers Studio 7, Prima Luna Prologue One, Marantz SA-8003

The stock (Chinese?) tubes in my Prima Luna Prologue One finally wore out after two years. The stock tubes sounded really excellent.

I decided to "upgrade." First to Electro-Harmonix tubes, which sounded decent but not as good as the stock tubes, and now to Mullards.

I know that tubes take a little while to "burn-in" but these Mullards sound awful.

They have a hard, clangy, echoing (microphonic) quality that none of the other tubes ever had. The soundstage seems to have receded backwards by a hundred feet. Everything sounds small and far away.

Is this how Mullards sound? I thought they were supposed to sound romantic. Is this all part of the "burn-in" process?

Before buying tubes from Kevin, he asked me what equipment I was using, not where I bought it. With that information, he told me which tubes would be best for my gear and I followed his advice. Since I didn't buy my equipment from Kevin, I didn't get the 50% price reduction that Layman would get. I have read both negative and positive remarks directed towards Kevin, but he was great with me and I am glad I bought the tubes from him.
