So let me start out by saying that this purchase was years in the making. I had seen several tube amplifiers that could use both EL34 and KT88 tubes and one in particular that also had triode and ultralinear operating modes. My end goal was to replace several tube amplifiers including my ancient yet beloved Dynaco Stereo 70 (ST70). It should be noted that several years ago I purchased a Yaqin MC-100 amplifier but my ST70 was simply better sounding so I sold it and started my search anew. For better or worse, I'm not a wealthy audiophile but I am a very good technician so I've been able to buy most of my audio equipment broken for pennies on the dollar and then over months or years, repair it as I acquire parts. This time however, I wanted something new so this was like buying a new major appliance since it cost the same as my washer and dryer. That notwithstanding, let me tell you about this amp. When the Willsenton R8 (R8) arrived, I was pleasantly surprised to find it was triple boxed. Given the weight of this amp is over 70 pounds it needed to be well protected for shipping and it's clear from the weight this is not cheap amp. My ST70 is light as a feather in comparison. One thing I found interesting is that it shipped with the tubes already installed but there was sufficient styrofoam and tape to keep the tubes in place. Nothing was broken and my poor body survived lifting it onto the audio stand (I still got it!). On the features front, the amp comes with a high quality machined aluminum remote. The remote has no power button but does have an oddly large mute button (huh?). The amplifier itself does not have a VU meter but features a large easy to use bias meter. Keeping with the quality theme, the power and volume buttons are machined aluminum with LED illumination (red for power and green for volume) as are the selector and TR/UL buttons. A tube cage is included and the vacuum tubes are Willsenton branded so clearly a lot of care was taken to continue the quality theme. Even without having heard a single note from this amplifier, I knew I had a beautiful piece of audio jewelry for my listening room. My first impression of the amplifier was positive when I turned it on and heard nothing after hearing the startup relay click on. No hiss, no hum, just silence. The amplifier defaults to triode mode when powered on and my first listen was Introit from Faure Requiem (Naxos). Playing through my Infinity Primus 363 towers, the opening pipe organ chord filled the room with power and authority rivaling some of the best tube amps I've heard and certainly better than any I've owned. About three weeks in, I had used the amplifier enough for the tubes to settle in and now there is a greater smoothness to the sound (it was never harsh) and I can easily hear a stark contrast between triode and ultralinear modes. It should be noted that I had a Yaqin MC-100 amp and the difference in the modes was barely audible. In comparison to my ST70, the R8 is a very different sound which is to be expected since they use both different types and brands of tubes and the ST70 uses tube rectification while the R8's rectifier is solid state. I cannot say that one is better than the other as I enjoy them equally. In conclusion, I must say that the Willsenton R8 is a fine amplifier. While it is by no means inexpensive, it is certainly a value leader as it is less than half the price of competitive "brand name" equipment while yielding uncompromising build and sound quality. While sound quality can certainly be improved (or diminished) by changing vacuum tubes, the buyer of the R8 can rest assured that the branded tubes that come with the unit are by no means a cheap add-on. I'm pleased to say that the engineering and care that went into the build and parts selection of this amplifier are worthy of the best brand names. Thanks for reading! ... show more

I don't write reviews but this is an exception because this amplifier is exceptional. It definitely needs the break in period. The manufacturer recommends 100 hrs. I'm approaching that now and I can say that the amp is coming alive! I've been skeptical about audio products that claim a break in period. This amplifier did not overwhelm me upon initial listening. But oh yeah, it's morphing into sonic bliss. I'm in my 50s and still own The ADCOM GFA-555 that my dad bought me for my birthday in 1984. I love that amplifier. I've tried other amps over the years but still use the ADCOM as my main. The other amps got reassigned to center and rear channels for Home Theater. I've been swapping speakers in and out on the Willsenton and it sounds great with all of them so far. Everything from low efficiency bookshelves to high efficiency Klipsch's. It takes their strengths and makes them better. I haven't tried my Magnepan MMG's yet. I should have done so before writing this review but I am listening now and couldn't wait to write this. The Maggie's are hard to drive with an impedance that drops to 2 ohms. The Willsenton has 2 sets of output taps and I'm hoping they are a good match. I read a lot of Audio Reviews and sometimes feel like the reviewers get a bit Audio snobbish with their flowery language. You know, "this amp has a relaxed presentation with excellent pace, rhythm and texture reminiscent of the BBC sound of the 60s blah, blah" Well now I'm the snobby reviewer. This amp is holographic! My high efficiency speakers aren't normally the best at imaging but holy cow! They image pretty damn great with this amp. Instruments are very distinct and separate in the music in a way I've never experienced before. When I was young my dad would take me to HIFI stores. His budget was NAD, ADCOM etc. but I could see him itching to own products like Conrad Johnson, Audio Research, Mark Levinson etc. I can say without hesitation that this Willsenton amplifier reminds me of those 80s iconic high-end products that my dad dreamed about. I'm using the Stock KT-88 tubes in both Triode and Ultra-linear mode. Both are fantastic with the main difference being that it drives woofers with more authority in Ultra-linear mode. But I can hear the benefits of Triode mode with small ensemble acoustic instruments and vocals. I'm officially an Audio Snob. And finally I can afford to be one. Thank you to my father for giving me the opportunity to dream. ... show more
