Willsenton R300 Tube Amplifier 300B x2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One

Product Information

But in this case I think the Mundorf Supreme SGO are in a similar size range to those being used - just better quality. I'd get to hear what people are talking about with SET amps and 300b tubes and at a price that wouldn't kill me if I don't like that kind of sound. I don’t see the need to excuse rude and obnoxious behavior. I appreciate that we view this differently and that’s fine.

I've been told that the basics of how one hears volume is that a typical 25W RMS (R8 in triode mode for example) amp has a maximum volume which solely depends on the efficiency of your speakers, the average impedance of your speakers, and finally, the size of your room and where you are sitting in relation to the speakers. What's more, for the ear to perceive a volume that is TWICE the volume which a 25W RMS amp can go to comfortably, an amp would need to be around 10 times more powerful - so around 250W RMS! Now that I have that out of the way, not all amps can drive all speakers at a given efficiency either, simply because some speakers are harder to drive than others. Further, I have also heard it said that out of solid state class D, A, A/B and tube A and A/B designs, that tubes are GENERALLY more capable of driving difficult loads. As your Monitor Audio speakers present a relatively easy load, I believe that you should be fine as even though your speakers are a little on the low side in respect to efficiency, in an average sized listening room, you should be able to reach quite respectable volumes. Of course the R8 also has ultra linear mode which boosts the output to 45W RMS per channel, although I find that triode mode is the more accurate mode. If you use the R8 amp to watch movies, by all means throw it into ultra linear mode where the design of the R8 gives more "presence" to the midrange area, i.e., the midrange comes forward in the soundstage. Ultra linear mode can also sound better for some genres of music too, although this is also reliant on personal preference as well. It is more expansive, more human, and has that true 300B character. The only catch is that t his is an amp made for speakers that are at least 90db efficient. Sure, it may drive some 87db speakers in a small room but do not expect any head banging to be going on. This amp shines with speakers that are easy to drive. Horns are WOW with this amp. if you take the time to research and do further reading/investigation you will find a better capacitor that will contribute to improved sound quality. I’ve had splendid success with the Duelund CAST copper foils. Considerations are available space for a given capacitor and the cost. No doubt there are other excellent choices available. These amps are usually the definition of what most people expect a tube amp to sound like.That is a good thing as long as the speakers have synergy well with the amp. These are a beautiful sounding quad of Mullard 6CA7 (EL34) xf2 and a pair of Sylvania 6sn7GTA angle-plates - both sets circa early 60's.On the Muzishare X7 model I suspect the Muzishare silver label on the coupling caps is covering a Mundorf EVO silver cap. They refer to the cap as Germany in origin and has the same 1200VDC rating. I may have to try to peel the silver label off to see what is underneath. Maybe someone on here knows which caps Muzishare is rebranding? The Muzishare R100 I have had for a while and is already for sale in the local craigslist. Very nice amp but I just do no need that much power or heat of the 845 tubes and it is also a bloody heavy thing to move. But no complaints on the sound quality. Very nice.

Overall the R300 gives the H4’s a sweet expansive sound that when set up right offer up a slice of that three dimensional magic. The Deville’s are more refined and have more of an even top to bottom coherency for sure, but the Heresy’s seem right at home with the 300B tube. The result of all this is just sublime! Compared to my excellent Elekit TU-8200DX (single stage, class A too, but it uses 6L6WGC tubes), it's a totally different musical universe, soft but with analysis, voices and beautiful timbres! Nothing hyper transparent here or lightning dynamics, but on drums, the Wellington surprised me! It is in no way soft and mushy, nor rough and hard.From my understanding the existing non-polarized caps are silver film. I do not think they are junk but for a reasonable cost certainly am willing to upgrade them. Two 5U4G vacuum tubes are used for high-voltage rectification. 1pcs of 6SL7 and 2pcs of 6SN7 vacuum tubes are used for the voltage amplifier and preamp stage. The power amplifier stage uses two Willsenton custom-made 300B vacuum tubes for single-end Class A power amplification. Beautiful music emerged from the Devilles but at first I was concerned as the sound was much too warm. I was missing that treble energy. The bass and mids were big, full and expansive but the treble was rolled off. Hmmm. I realized I had my Cardas Clear Reflection and RCA Cables in. I removed those and replaced them with some (less expensive) Nordost Blue Heaven speaker cables and RCA cables. Some posters blather on about changes without the slightest regard for rigor. To boot, they evaluate whilst intoxicated and at injurious levels. I endured too many sessions with doped up musicians to have any tolerance for audiophools.
