So I bought the Willsenton R-800i


After I bought the Klipsch Cornwall IVs recently it became apparent quite quickly that to make it really shine it needs a tube amp to drive it. (For me at least.) After doing some (=endless) research, considering the options (budget, shops nearby carrying models I´m interested in, etc.) and also asking around on this very forum I decided to go for the Willsenton R-800i. None of my friends here shares my excitement for audio stuff or even has a comparable system, so what´s now in my living room is the one tube amp I know. And I´m delighted. Together with the speakers it gives the music the presence and glow that I so desired.

Of course I can tell that there´s more potential in this amp and I already exchanged some of the stock tubes. There are more on the way and I can´t wait to test them. For now my financial means are a bit limited so I´m not ordering Western Electric and Takatsuki 300Bs just for the sake of comparing them. In fact I´m waiting with those a bit and go for the others first.

Searching online I find a lot of information on English language forums. Somehow tube rolling is not discussed as much on the German forums I checked though – and out of curiosity (and because they were pretty cheap) I went for both West- and East-German ECC83s and a fairly random mix of other tubes from the US and the Soviet Union. I´m waiting for them to arrive and not being able to read about some of them it raises my curiosity how they will sound. Maybe crappy, maybe not so bad, maybe even very good. I´ll see. Tube rolling will take some time and I don´t mind. The amp is there to stay for quite a while.

There´s an exhaustive thread on the Willsenton amps and fitting tubes here but since I found people´s comments on this forum so helpful I´m looking forward to hear from you. I´m open for tube recommendations and would like to hear anyone´s experience with the Willsenton R-800i. Or maybe someone has questions?

As for the tubes:

805 – stock replaced for Cossor
300B – stock
6SN7 – stock replaced for Sylvania GTBs, waiting for Fonon NOS (Soviet, 1979, a bargain for 10€)
12AX7 – stock replaced with current Mullard model, waiting for West German ones from AEG and Telefunken, East German ones from RSD and Funkwerk Erfurt (both used) and also Sylvania JAN 5751 NOS (a military model)
5U4G – stock, waiting for RCA NOS black plate and Svetlana NOS „Coke Bottle“

Yespoke33, but that's a different amp, the less expensive kt88 one  which is also supposed to be very nice.

@2psyop Probably some would argue that „organic“ and „pure“ may be a contradiction, but I think I know what you say. And what @sns says goes for me in the same direction: Event though tube amps have their particular characteristics such as the warmth it doesn´t mean that it can´t handle all kinds of music that have very different sonic signatures. Maybe my comment on tube amps not being able to handle super clean style (such as Alva Noto) or something else was uninformed. And I´d be happy about that. Thanks for the correction! This changes the position of my goal posts. I´d be happy to achieve a warm but still linear sound that doesn´t let its qualities clash with music that may not need them.

Because the setup will not play vocal jazz only. My taste is also pretty broad, from Renaissance Choir Music to Chaotic Hardcore, from Ambient to Classic Rock and so on. So it has to retain some kind of neutrality while being tubey. This tube rolling adventure is about finding out to exactly what extend this can achieved.

@philgo01 All I can say is that whatever question I had was answered within half a day or a day via email. They also asked after I bought if everything arrived safely and if I was satisfied. The amp came double boxed with heavy foamy plastic inbetween. An info sheet inside said that with improved packaging they pushed the return rates because of transport damages to (as far as I remember) about 1%. Returning would definitely be a hassle but somewhere I read they were very helpful once it happened to someone. But yeah, China is not downtown.

@noromance I´m not exactly sure what you are referring to here. As I said my reference is the old Rotel I own, which it easily outperforms. Comparing to other tube amps was impossible. Going to other cities, numerous shops with different setups and rooms, probably even on different days to check out other amps that fit my criteria seemed not a desireable way to compare amps as neutrally as possible. Maybe you see that differently, fair enough. Sure, I could start with a smaller tube amp to get a feel for it. But as I mentioned before, I´m impatient, if this is the right word here. Why not go for the real deal right away. The Willsenton is cheap. Of the models I narrowed my choice down to it was still the cheapest while getting the best reviews. And cheap in this case means no dealer round the corner. It´s something, a gamble you might say, I have agreed on by buying straight from China. And that´s not something I´d recommend to everyone. It´s just what I did. And do I know that it is the best tube amp? I don´t. Does it make me happy and feel like I made a good choice? Definitely.

@ibmjunkman Thanks for the hint. Being able to speak german, english and polish already gives me quick access to far too many offers. I saw that hifishark.com automatically scours some Italian websites. So I may even buy a tube or so from there in the future.

That gives me the idea to set up a tube website list. I came across so many websites ever since I started getting into the topic, I definitley have no overview. I forgot the url of a dealer that just put up NOS tubes on his blog once s/he got new stock in. Let´s see.
There are some nice tube comparisons on websites, blogs and in forums. I wish they were all as extensive as this one about 6SN7s.

@poke33 Thanks for pointing to this, but it´s about the R8, not the R-800i model. They come with a considerably different choice of tubes so there´s only so much info I can take from this. Like what he says about 6SN7s.

philgo01, for those of us with trepidations regarding service after the sale, if you buy these amps through Amazon (including the smaller brother R8 which I've been eyeing after hearing it drive some Lintons), you can buy a 3-year electronics warranty for about $160.  Likely worth it in the long run I'd think, just for peace of mind.  All the reviewers say these Willsenton integrated amps are built every bit as good as the also communist China made Primaluna Evos.  Due to their popularity, Willsenton had to move to a larger factory space recently. Of course, Primaluna has a brand name recognition among "audiophiles" so resale percentage value would perhaps be higher, however if you are only caring about sound quality, the R800i (or the R8) might make sense - with an American company warranty. 

 If one can purchase a legitimately backed extended 3 year warranty for 160.00 USD this is good news and reassuring. It seems that from reviews and word of mouth the Willsenton amplifiers are a quality built product. 

I find it very interesting they can offer a 805 (DHT) output tube that requires high voltage circuit/power supply/transformer and driven by another DHT 300b in pure class A at this price point. And do so in a presumably very reliable package. That’s quite impressive. This is an ambitious undertaking.

Beyond the far more common class AB tube amplifier using pentode type tubes in a push-pull circuit.
