HiFi Cave just posted a video on his 2nd try with the R300. Once again, speaker pairing is paramount, but overall very positive.
Ordered a Willsenton R300
Everything I have read about this 300b tube amp has been very positive, particularly Steve Huff's review on his website. I have always thought I would love the sound of 300b tubes and this is my chance to get one for a very modest price. It ought to drive my Spatial Audio M4 Triode Masters very nicely. I will report back my impressions of the amp when it is fully revealed to me.
