Inexpensive Tube Amps


Anyone have any experience with the following?  I want to try one just to see how the sound compares to my Yamaha and Denon solid states.  Since the Denon is living on borrowed time I will likely have to replace it this year anyway.  Looking at the Nubsound and noted a Germtune that is identical to the Nubsound but costs a bit more.  Reviews are largely good including those on other forums.

The "where I wound up so far" story: I became enamored of the sound of my Had amp used with a pair of new 93db Sonist Recital 3 speakers until I put my previous Silverline Preludes (supposedly 91db) back in the system just to see how they sounded with the SEP amp. Sold the Recitals as the Preludes sounded more to my tastes, and that got me thinking about efficiency generally which led me to a pair of Klipsch Heresy IIIs. The Heresy IIIs at 99db are perhaps the most efficient 3 way around without getting into large horn loaded boxes, and they are a surprisingly coherent and clear speaker. I say surprisingly because I assumed I was too hip for a silly Klipsch speaker that had been around in some form since the steam power era, and man...these things are great, but need a sub or two. 
Will62...I'm not trying to talk you into anything and hey, I get it, and even mentioned that I thought your amp seemed pretty cool. I'm into inexpensive gear with high value and great sound as I think it's simply more fun to seek out that stuff.
I had never heard of the TubeCube7 although I've bought tubes from "the depot" from time to time...interesting. Note that my World Class "El Fabuloso" Dennis Had Firebottle SEP HO (It's a HO...says so right on the front panel) cost only 1100 bucks used. His new stuff is around 1500. Cheap but amazing, a good fit for any fiscal conservative. "Get what you pay for" absolutely does not apply when poking about in the morass of audio gear, but audiophile research does.
Primaluna and Hegel…(maybe somebody already mentioned this) they're made in China. 
I owned a Jolida 502P for years and only replaced it as I became interested in Dennis Had's little hand made amps. But the Joilida was amazing for less money than any comparable tube amp out there when I was shopping around, but was sorted (and had a parts "upgrade") after manufacturing by the Maryland Jolida techs…so maybe that makes a difference. I also currently own a rarely used but well made Chinese $50 "Bravo" tube headphone amp…it's cute and sounds great with the better-than-stock 12AU7 tube I put in there. They immediately sent me a free new power supply when the original failed…whoever "they" are...
