  MAOP 7.2 matched pair (£181.00 Excluding VAT)

  Finally got the MAOP 7.2s up and running.
  ​A bit of context: I’m a recording engineer, not an audiophile, and wanted a compact, engaging system for casual lounge listening. Since I’m averse to ported designs and prefer keeping crossovers away from the vocal band, a full-range driver seemed like the ideal route. Going against the grain of typical large, vented builds, I mounted them in very thick, 3D-printed sealed enclosures with an internal volume of just 3.5 litres. The goal was to relieve low-end excursion using a dedicated sub rather than chasing sub-bass from the drivers themselves.
  ​Because the satellites were finished first, I initially ran them full-range. I used to be skeptical about driver burn-in, but these completely changed my mind. Out of the box, they sounded harsh and mid-forward, reminiscent of vintage Auratones. Around the five-hour mark, however, they loosened up significantly, and the bottom end fleshed out enough to make me wonder if a slightly larger sealed box might have sufficed on its own.
  ​Now the sub is in place: a matching dual-opposed Tang Band 5.25" sealed enclosure, integrated at 100 Hz with a 12 dB/octave filter (24 dB felt too disconnected).
  ​At around 60 hours in, the MAOPs are performing brilliantly. They are ultra-revealing and precise, but post break-in, that detail never feels fatiguing. Given the listening distance and high-frequency beaming, I run a slight 6 kHz shelf boost, though that may come down as the top end continues to open up.
  ​They are remarkably capable drivers that uncover subtleties in mixes I’d never noticed before. Highly recommended, just be prepared to give them the mechanical run-in time they genuinely require.

  Hypex Nilai500 Mono Kit (£690.00 Excluding VAT)

  A long term review as purchased in Jan 2025. No problems buying from Stefan at KJF. An excellent service to be honest. The amplifiers namely Nilai 500 mono blacks have been exemplary. Absolutely no problems with them whatsoever. The build can sound a bit daunting but in reality just follow the instructions. There is nothing that complicated in the build. It's only a case of assembling the kit. I don't have any standby trigger out on my pre-amp so I've used a 12V wall wart via a remote controlled power plug to activate the amps via the 12V trigger input. Works a treat as I can power everything up by remotes now. The sound is something else. But I guess anyone would know that if they where going to purchase. Superb I can't say more. Thanks.

  MAOP 10 matched pair (£260.00 Excluding VAT)

  I purchased one from the very last batch. At first, the sound was completely terrible, but after 400 hours of burn-in, it now delivers fantastic sound. I have housed it in a 9-liter cylindrical sealed enclosure, crossing it over with my DIY subwoofer around 100 to 150 Hz using a DSP, and the integration is absolutely flawless. I feel incredibly lucky to have acquired such an amazing driver.

  Hypex Nilai Stereo to dual mono adapter kit (£75.00 Excluding VAT)

  Same story as the users above: more grip/control, more air between the sounds, more stable and deeper soundstage. Thought the stereo was already great, but the diff was bigger than expected, luv the upgrade!

  Loudspeaker Crossover Design Service (£95.00 – £120.00Price range: £95.00 through £120.00 Excluding VAT)

  Thanks guys at KJF Audio for the great crossover design. After realizing that designing a real good passive crossover for my project, being high quality / high power mid high tops wasn't a thing I'd bring to a good end myself, lacking experience and the right software and equipment I decided to ask KJF for help. Within a couple of days after submitting the ZMA files, datasheets of the drivers, baffle layout and my wishes I received the design including the vision of a very experienced audio specialist and the simulation graphs of the impedance, frequency response, delay and spreading. Started building the crossover right away and after measuring finding out that the real thing was almost exactly the same as KJF's simulations. The mid high tops with each a JBL2123H and a Beyma TPL200H crossed around 2k sound as I only could dream of: flat response within the intended range, insanely fast and direct, perfectly smooth around the x-over frequency. And that from decent living room volumes to an insane spl without getting screamy. Simply said, couldn't be happier!

  Hypex Nilai500 Stereo Kit (£1,030.00 Excluding VAT)

  I purchased this Nilai amplifier to drive the front L/R speakers in my system & partner the 8 channel MA-01 I already own, which drives the 8 surround channels.
  The Nilai sounds absolutely neutral, doesn’t get hot, even after hours of use & was a pleasure to assemble, everything fitted together perfectly.

  The service from KJF is always first class too, I ordered this in the afternoon & it was still delivered the next day.
  I highly recommend this amplifier & KJF Audio.

  Frugel-Horn Lite DIY speaker kit (From: £239.00 Excluding VAT)

  Impressed.
  The build: with care the build - even on the kitchen table - is straightforward. Unfortunately I saw the older instructions first so bought a range of clamps (£200) but these are now unnecessary. It is a pity that I was "not permitted" to know the name of the tape used in the video because I think it would probably be better than the tape I used (Scotch blue). The method works well and the results are good - I used a bit of wood filler for the inevitable gaps but when sanded and varnished the birch ply looks super.
  The sound: these are good speakers. Clear, precise and enjoyable. As one would expect, not great for loud, bass-heavy tracks. Certainly genuinely exceptional value for money. I have the MAOP drivers.
  The Look: (if important) to me they look super in the room. The curved cabinet adds a certain "je ne sais quoi" and there is definitely a sense of "I built those" pride.
  I intend to build the XL version next - interested to hear the differences!
  If you're tempted - give in and get a pair.

  Alpair 5.3 - Gold/Grey (pair) (£70.83 Excluding VAT)

  These were built into the compact multichamber enclosure in 15mm oak. At first use fabulous detail and some bass. After a month of intermittent use the bass really came alive. These are now in use on my studio mixing desk in preference to Beyer closed back cans or LS3/5A 15ohm. Amplification for nearfield with Naim Nait 1, around 15 watts is more than enough to fill a medium room. Stunning
