Willsenton vs Billie MK 1

Sorry......Using Parasound as pre-amp......B&O sub. 95% streaming vis Node 2

It seems to have a decent impedance profile (though I have not seen a curve):
"The sensitivity as reported by Merlin is 87dB/W/m, and the impedance is 8 Ohms nominal with a 6.5 Ohms minimal rating."

I'm not sure what you can spend, but the Quicksilver Mid Mono might be nice:

@troutbum - What are your feelings about the Billie amp and why do you want to change?  

I have had the Billie Mk2 in service for the last 2 years.  Driving Golden Ear BRX monitors.  It sounds good, not great.

Curious to your comments.

I was interested in the amps made by Willsenton. I was not particularly put off by Chinese made tube amps since I have a Line Magnetic integrated tube amp now. The R8 was getting rave reviews and I was Iooking hard at the R800i. Then I saw a YouTube audio tech who reviewed these amps and found faults in the design of both amps. Upon looking further I had decided against the brand.

A friend of mine had the Billie as well, but he moved on and didn't look back. But, he has more expensive tastes than I. Actually, I like the Billie. I had been thinking about upgrading from my Merlin TSM MMs, but most advice said keep them and upgrade components. That's where I am.
