Hi Anthony I just wanted to take this opportunity to thank you for all your help over the last few years as I built my home theater system. The subwoofer amplifier has been running smoothly now for a couple of weeks and my system is now completed. All the equipment you have sold me over the last few years is running with faultless precision. Thanks so much for responding to every enquiring email I sent.The attached photo shows the main guts of the system all of which I've built myself apart from the black processor on the rack. All the aluminum front amps are full of your gear.Thanks again. Steve Happy Customer Auckland New Zealand

Hi Anthony, I have finished the modification and it's magic ... the speakers never sing like that (focal elektra 1027 be) the sound image is open, soft and very precise, all the little details are there, nothing is aggressive and the bass is firm, just punchy. these amps give me chills, the musicians are in my living room and I rediscover my music! Anthony you are a music magician. thank you for your presence and your work. Merci beaucoup ,portez vous bien vous et votre famille au plaisir Christophe Henri ,  saint michel sur orge France    

  I recently purchased one of Holton Audio’s  One-Zero-Zero Supreme power amplifiers that I had been keeping an eye on for some time now and very glad I did. I’m not a sit down and take notes type of  bloke, but paired with my Osbourne Epitome loudspeakers, a whole new level of sound has opened up. Sounds like I’ve moved the speakers further apart but they are still in the same spot, not sure how that works. Hearing a lot of small details in my favourite tracks that weren’t there before, and a lot of extra punch in the bass, many apologies to the neighbours.  I will have to revisit my music collection now to see what I’ve missed. Will be an enjoyable chore. Anthony was a pleasure to deal with, and I can’t recommend this little marvel of an amp highly enough. Troy P Victoria, Australia
