Hi-Fi tuning & upgrades
Want to hear true Hi-Fi for sensible money? Most likely you don’t realize what your everyday DAC, CD player, streamer or converter is capable of.
Why an upgrade works
Manufacturers always engineer for cost. Their designers are forced to simplify circuits and save on parts in every stage — regulators, filters, capacitors. That is why a proper upgrade means: premium audio components instead of stock ones, sensibly increased filter capacitance, reinforced power subsystems and corrected circuit design — true to the original engineering intent, and often beyond it. The device finally delivers the potential its designers built in.
Why an upgrade beats buying new gear
There is no point selling your DAC at half price to overpay for a bigger model: what you already own can deliver a gain that outweighs both the unit’s cost and its nearest rivals.
How a job runs
Diagnostics
I analyze your exact model from its service schematics before even seeing the unit.
Forecast
You get a predicted quality gain up front — you know what you’re paying for.
Plan & quote
A circuit-level plan with a parts list and full quote. Where possible — tuned to your listening preferences.
The work
Only after your approval. Only genuine parts from authorized distributors.
Warranty
Every job: 3 to 12 months depending on complexity.
What I work with
My profile is digital audio sources: DACs, CD transports and players, streamers and network players, converters. Also power supplies and routers inside the digital chain, plus HELIX digital processors for car audio.
Shipping
Gear can be shipped from anywhere in Ukraine and from abroad — EU and worldwide.
Frequently asked
How much does an upgrade cost?
It depends on the model and the depth of the work. After diagnostics you get a plan and a quote — work starts only once you approve. Ballpark figures for the authored lines are in the OLX listings.
How long does it take?
From 2–3 days for compact DACs to 14–20 days for reference platforms.
I’m not in Kyiv. How do I get the unit to you?
Shipping works from anywhere in Ukraine and from abroad — EU and worldwide.
