Excellent for a cheap preamp

I purchased this little amp as the output from my computer was just a tad under powered for my Sennheiser HD 598SR headphones.

Delivery was quick (despite ordering over the new year) and was well packaged, noteworthy that the valves supplied are Chinese.

At first i was slightly disappointed with the hiss, crackling and popping i got through the headphones, however this is my first time using valve amplifiers and of course after some research i learned you are supposed to let them warm up first! the sound gets better and better with time and after about 10 hours of play time the hiss, crackling and popping has almost gone (apparently takes 20 hours for new valves to "burn in" completely)

As of this review the sound is excellent, i am no audiophile but this is the clearest sound i have ever had, the bass is 10x better with the amp and the volume is now able to go well beyond comfortable listening and as a bonus it also looks excellent! especially in the dark.

In summary if what you are looking for is a cheap amp that makes things louder, this is an excellent option!Read full review

Terrific value and unexpectedly good sound quality

My AKG K702s sound great through this tiny amp on stock tubes but even better after Mullard M8100 tube swap. It drives these headphones with so much more authority and musicality at 10 oclock volume compared to 12 oclock volume on my ifi Zen Dac V2 even with true bass on. It's a no brainer purchase especially at this ridiculously low price. A great entry into hybrid tube amps.Read full review
