I used the EH 6550's in a Rogue Audio Tempest Magnum and they are great, very transparent with great bass control.
Has anyone used the Electro Harmonix 6550 tubes ?
I currently have the Svetlana 6550 's in my VTL & think they are great . Someone suggested the EH 6550's and said they are the best 6550's . What do you guys think ? Thanks!
