If I’ve repaired or upgraded your amplifier, or you’ve purchased parts or equipment from me, I’d be grateful if you could take a moment to leave some feedback.
Your comments not only help a small independent specialist service, but also provide future customers with confidence when deciding who to trust with their equipment. Genuine experiences shared by previous customers are often the strongest foundation for that trust.
Thank you for taking the time to share your feedback.

Had my PSW2010 repaired that is 22 years old. Decided on a full upgrade of all potential ageing parts replaced. The system now sound loads better, as good as new, if not better. Very good professional service.
Very professional, helpful, competent service at a fair price, repaired a subwoofer and also a Quad pre-amp for me. I can’t recommend Stoyan highly enough.
Stoyan has proved to be a knowledgeable and provide clear advice/diagnosis and for me this led to a great repair on a beast of a subwoofer KEF PSW-5000. I thoroughly recommend his work!
I asked Stoyan to repair my Kube 1, which had completely failed and then a week later perform a full upgrade service on my PSW2500. Both amps have now been returned and are in perfect health. Communication with Stoyan was superb and I can not recommend this service enough. Stoyan is a true professional.
Used this Guy after finding him on some threads back in jan -feb 2019.Posted my subwoofer pcb to london from Scotland. No dramas at all went for the full overhaul & upgrade of suspect components of the Kef PSW 2010.
100% GENUINE GUY HERE.
Bloody Marvellous job
So pleased that I stumbled across Stoyan for my sub repair. He was able to quickly assess what the problem was, provided me a range of options to consider, instructions to pack and send were an added bonus, to top it it off guidance to prevent the issue again. can’t ask for more.
Great, honest and professional service.
From start to finish Stoyan has been very helpful and professional. Very clear instructions and pricing, very responsive on e-mail and the repaired AMP turned up on time and now sounds better than when i first bought it all for a ridiculously low price. Strongly recommend him
Stoyan is TOTALLY professional in the quality of his work, and is extremely helpful and well informed about all aspects of the KEF 2010. He has given me information which I had had no knowledge and although my subwoofer and surround sound system is some 18 years old, only now, thanks to Stoyan, have I been able to set it up correctly. Absolutely recommended!!!!
what an excellent service from a very helpful man from start to finish he puts your mind at rest and i will tell others about you.
thank you very much..

Just collected my KEF PSW2000 Subwoofer speaker from Stoyan fully reinstated and working. I have had this unit for nearly 16 years and it suddenly started buzzing loudly as soon as it was switched on. I found Stoyan from a Google search. He is very knowledgeable and has been extremely helpful. He repaired it successfully and thoroughly. He offered a total overhaul service plus repair which I thought worthwhile. Stoyan has been a great find and I wouldnt hesitate to recommend him. He is also a very nice person to deal with.
My Kef PSW2000 stopped working, found this site on Google an glad I did, he is excellent he gave me option on how to send it to him, plus he confirms it arrives, plus he found problem within days and give you option on how you want it fixed, prices are very reasonable, had it back in and up and working within the week cannot fault that service
Great to see good people still care about what they do
Many thanks top man
My sub was buzzing. KEF could not help and a new one was black (so not matching my silver ‘egg’ speakers), and expensive. Mr Monev was brilliant. It’s now back and working, and hopefully future-proofed, and that’s what’s most important. But it’s all the other stuff that’s so impressive from how to disconnect it through to how to look after it properly. And the service and updates are terrific. Thank you.
Having bought a Kef 2010 from ebay I was dissapointed when it arrived faulty. Luckily I came across Kef repairs in my Google travels. I contact Mr Monev and to say it was a smooth process would be an understatement. The website is exceptionally helpful and transparent. The service and prices quoted was exceptionally. Would wholeheartedly recommend this service. I now have a fully functioning sub for a very reasonable price. Thanks indeed.
I am really impressed with the service I have received from Mr Monev. He did a full upgrade of an old 2010 and made a great job of it. It sounds excellent.
There was a little problem to deal with it when I got it back from him but he was really keen to help and soon had the problem sorted.
He does a good job and is really helpful. I can recommend him.
Just had my PSW2000 returned after repair and upgrade.
Great service, communications and work.
All went smoothly and speaker now better than new – all working great.
Also get helpful advice on all aspects – packing,diagnostics,setting up etc..
Hardest part is packing the amplifier and arranging courier – get advice on this as well.
Very happy and highly recommended.
After a prolonged period without my PSW2000 I contacted Stoyan to see if anything could be done to get it repaired. After a detailed analysis and review of what was needed I was presented with 3 options and prices for the repair. Needless to say that my sub is now in perfect working order.
The level of service provided was second to none. Great communication, care and attention to detail and I can 100% recommended his service!
Keep up the good work and I’ll definitely be in touch if I have any other electronic devices that need fixing.
Thanks,
Marc
Received my PSW2010 amp back today, all working great. The level of service Stoyan provided was second to none, from initial contact, to the detailed work carried out and prompt repair and return. A very professional and rare customer service. Highly recommended for your Kef repair or any other electronic issue.
Many Thanks
Thank you for the repair to my KEF sub-woofer. A prompt & efficient service and now back home working, 10 out of 10.
A pleasure to deal with someone who goes beyond being helpful.
Always prompt in keeping me informed about what was happening with my repair.
Cannot recommend highly enough.
Amp now working like new.
Fantastic service, very knowledgable, repaired and advised of upgrades to prevent future problems.
Very quick repair time.
Thank you.
Highly recommend this service. Very responsive on email, informative, great service and the sub works like new again.
Thanks very much for fixing my subwoofer, and for the quick service, and for all the information you provided. It works like new again. I would highly recommend your repair service to others.
Top guy, top service. Knows exactly what he is doing and no guess work. Would recommend every time.
My Kef subwoofer had been out of action for some time. I found Mr Monev through Google and quickly established that he should be able to help me. He recommended a source for comparing couriers and I quickly had my subwoofer with him.
He speedily diagnosed my problem and gave me a selection of repair and upgrade options. Then quickly had it back to me with a PDF of useful connection tips.
Great service and friendly emails. I’d highly recommend this service.
Thanks very much, sir.
Wow, what a service. Couldn’t believe how professional it was.
Very quick at responding to my emails. Always replied with a smile. An absolute gent.
I opted for the full upgrade service and couldn’t believe how many bits were changed. You get these back with your sub.
Such a pleasure to do business with and so simple. I now have my sub back in perfect working order.
Thank you!
