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.

Thats a lot of cool features for that price.

I think I’m most interested in the imaging and the details on the highs. Theres a little muddiness in the midrange but that’s not bothersome. The AI is very musical and sweet and I do want to keep that quality.

Here's my rig:

Magnepan MG .7
Audible Illusions Modulus 2d
Bryston 4b-st amp
Rythmik f12 sub
Bluesound Node

Your amp requires 1.4vrms to reach maximum power.  Your sources are all digital which means you are already above 1vrms into your amp.

Let me pose the the question of why do you need a preamp?  Adding amplification that will be deamplified via the volume control can only add distortion.   Have you considered using a DAC with a built in volume control or a passive volume control such as a transformer volume control

He just tried a tube preamp (AI) and found that it sounded MUCH better than his passive preamp.
I previously was using the Mod Squad line drive passive preamp. The difference in sound quality astounding. The passive Mod Squad sounded two dimensional  in comparison. And the magical thing was, mind you I have never heard a tube preamp before, was that the  AI connected the note playing with the note that it just passed and to the note that it would it would soon become. It's amazing
