Hello! Thanks for admission! I have a mid-fi system comprising 5.1 Hales Revelation 3 speakers, Parasound 5 channel amp, Bluesound vault, Oppo 105, Tubes for Hifi preamp for 2 channel music, and an Outlaw LF1 and Emotiva processor for home theater. Cables are all Blue Jeans. I roll 12au7 tubes and always looking for budget improvements to my system. I mostly listen to jazz, folk and alt country. Looking for a good deal on a music sub and thinking about upgrading my preamp.
