I haven't heard any $1500 tube preamp that can compare with a "tweaked" Tubes4hifi's SP14. By "tweaked" I mean put some better parts in it - Duelund/Jupiter/V-Cap output caps, good quality resistors in the signal path, better components for the PS, good attenuator, Shuguang CV181 tubes, etc. The price would go up from $1500, but you would have a preamp that can easily compare with a lot more expensive preamps. If you are into DIY you can buy the kit from Tubes4hifi and upgrade components yourself. Otherwise you can go to Don and get his version.
Are there any $1500 tube preamps that that can compare with Tubes4hifi's SP14?
Reviews on the Tubes4hifi's SP14 are consistently positive and so many people are blown away by them. I haven't heard one but I want one. I want to upgrade and would like to know if there other ones that can hold up against the SP14 at the $1500 price point.
