Anyone own a Red Rose Preamp?

I own the Hovland HP-100. I have not heard another preamp at any price that compares in many ways. Certainly there are some that are better in some ways, but not the important ways. There is the difference. I have heard Red Rose equipment at Mark Levinson's store on Madison Ave. in NYC and at Home Entertainment. I cannot remember if I heard the piece you mention specifically. I am a fan of his former Connecticutt company, not among the impressed with the new NY based firm.

Just a quick note,

I also own an audioprism mantissa and I am almost positive that the silver signature while much costlier did not come with the upgraded power supply(for the cost of the silver mantissa you would think it would have).

the upgraded power supply is 3 times the size of the standard one.

My buddy here has a silver mantissa and the PS is identical to mine.

aloha!

How many wpc?  Is the Mantissa the same thing as some forums call Mana?

@geworthomd The Mantissa being spoke of is a preamp. My best, MrD.
