When I changed tubes with Raytheon, new sound made me very happy. These tubes produce more dynamic, detail sound with wider stage.<br /><br />Thanks, Mr. Koray.scaltinkayahttps://www.blogger.com/profile/02360524166242316867noreply@blogger.comtag:blogger.com,1999:blog-7987345819908076211.post-80131390289071274582014-06-17T05:40:23.973+03:002014-06-17T05:40:23.973+03:00Lively, detail, balance, and a very good sound sta...Lively, detail, balance, and a very good sound stage and wonderful 3D image. They give a bit energy on top. Bass is deep and tight. I first listened to CDs, I feel the sound a little too bright for me. But when I spin LPs vinyl - BINGO ! A sweet vocal, airy and silky high, and never sound bright at all on the LPs. And what most impress me is these tubes are very very quiet. I like them more than PSVANE 12AU7 new production tubes that I was previously using. And cheaper than the PSVANE. I am ordering some more now.Anonymousnoreply@blogger.com
