My system is tri-amped, the Aksa 55's (1 of 2 assemblies shown)
running top and mids - as can be seen, transformers are remote with local regulation.
The TLP is running Multicaps as (output) DC blocking caps.
Audibly: stunning. Visually - still working on it.....

Chris Wronski; Chicago IL, USA  

The chassis I used is made in the US by BUD.
The two stacked boxes for the chassis worked great for me. I don't know if I really needed it, but this was cheap (relatively) and easy to do.
The rest of the system is always under construction with some minor change.
If I ever get done building speakers I will look into playing with a new or
modified CD source.

George Cherhit; Sacramento CA, USA  
The chassis is a DIY design measuring 17"w x 12"d x 3 1/4"h, the same design as Dan Schneider's amp as featured on Hugh's former web site, only with brushed stainless front and rear panels.
Andrew Gartside, Sydney, Australia  
The amp is an early 100W model, upgraded to Nirvana spec in early-2005. Caps are Siemens, by-passed (out-of-sight) with SCR-fastcaps. I suspect Hugh's own PS design would sound better, but I already had these. Chassis is marine-ply. This is the most musically consonant SS amp I have heard and one of the outright best amps, full-stop. Other amp favorites are Audion Silver Night, VTL225 and Audio Matiere Atmosphere

I went for the monobloc version because of the space constraint I have with placing my equipment in the center/between my speakers. Also I can use a shorter run of speaker cable. Internal wiring is Cardas throughout. Beside the magical midrange and dynamics, the great bass definition and control have great influence on my decision to use it for driving my basshorns in a bi-amp setup.
Nels Sorenson, Beverly WA, USA  

My system includes 55W Aksa w/ Nirvana tweaks, Foreplay pre-amp with stepped attenuator, Anticipation and Auricaps,
IPL S3tlm speakers - incredible bass, great fun to build
I'm REALLY enjoying this system. Like the simplicity and clean, detailed, liquid, POWERFUL sound. Highly recommend all the kits in the system.

The case is a cut down 2U 19" rack case with the transformers and regulators on a full-floating sub-chassis. I'd like to get a brushed and anodised front panel at some stage to replace the powder-coated one.
The amp has the Nirvana upgrade installed. It sounds amazing!
Nicholas Dunand, Melbourne, Australia  

The case, transformers and Caps came from an old magazine 100W Kit amp. The E.I. trannys have copper EMI shields and have posed no hum problems at all. I built the soft recovery rectifier onto tag strip (pic, centre) and added the Nirvana upgrade.
Definitely worth the extra!

Ian Miller, Adelaide, Australia  

Layout was planned by physically laying out the major components on the desk and working out chassis dimensions required.

This resulted in an AKSA built like a brick outhouse which of course is the ONLY way to build anything to last!

The AKSA exhibits undetectable levels of hum, hiss or anything else even with an ear up against the speaker.

Sean Dwyer, Bourke NSW Australia  
The AKSA case is 3mm steel folded into a U shape. The amps are mounted to a 13mm MDF base plate which slides into the steel case. The front panel is a 25mm slab of Sydney Blue Gum (Euclyptus saligna) cut from my families property and is attached to the case by four M10 bolts. Not only weighs a ton but looks like a warehouse and sounds like an opera house!

The 100W AKSA I helped to build with a friend. We were so proud of it we secured a perspex top so we could admire our handiwork inside!

The TLP case is my own design, and uses perspex and a few industrial design concepts. It sounds wonderful!

 

Rick Krzywniak, Melbourne Australia  
This 100W AKSA enclosure was built entirely of timber. The mains switch and all terminations are at the rear; the front has only the level control (a 20K ALPS) and two blue LEDS, left and right, to indicate power on.
Andrew Redwood; Melbourne, AUSTRALIA
 

AMPLIFICATION:
AKSA 25w/55w/100w modules per side. Two-box construction with power supply case behind amplifier case and connected by 13 wires (+/-/earth to each amp module, 3 speaker return wires - connected back to the PS star earth - and the amplifier case earthing connection).
Phantom Audio MC phono stage. I am waiting for Hugh to release the GK-1 line stage preamp… I still have my original Naim 12S preamp (all my other Naim gear having been traded in on the phono stage and a new arm, after being trounced by the AKSAs).

SOURCE:
LP12/Lingo turntable. Currently with a Dynavector DV505 arm and Benz Ruby 2 cartridge. The Dynavector is shortly to be replaced by a Graham 2.2.

The turntable sits on a DIY "Vibraplane" acoustic isolator (see enjoythemusic.com).

CABLES:
Interconnects (except the cable from arm to phono stage) are all made up from Allan Wright's "Super Cable Cook Book".
Speaker cable - currently nothing special but soon to be TNT-Audio's UBYTE-2 cable.

 

 

John Banas, North Carolina USA  

Both AKSA amps are now up and running! So far they sound fantastic after just a few minutes of running in. I have used a lot of high end gear like ARC 100MKII, BATVK200 & VK60, Conrad, Hybrids, ASL, and the list goes on. I must say that the AKSA is one of the best I have heard. Smooth and detailed without any solid state glare. Soundstage to die for. My next project will be to build either two more 55 W stereo amps or one 100 W stereo amp to run the base of the Orion dual bass drivers.

 

 

Lyndon Brown; Newcastle, AUSTRALIA  

My Aksa 55 is my first major DIY electronic project. Construction is straight forward as long as you follow the instructions. I had some problems understanding the testing phase but managed to work my way through them. As for technical support, I can only restate that it is A1.

My Aksa is built into a 2U rack unit from Jaycar, a local supplier. Toroids are from same supplier. I wanted the layout neat, and tried to keep the AC wires away from the PCBs and signal path. I cut the heat sink in half and came up with the layout you see.

Sonic Impressions? I must preface my comments by stating that this is my first foray into quality HiFi, but I do however have a clear idea of what I like and have listened to quite a number of systems in my audio journey. Clean, transparent ,tight is what I am after. So how is it? I received the “Big Phat Band- swinging for the fences” DVD-Audio in the mail yesterday just in time for testing. Slipped it in, selected track 9 “There’s the Rub”, and proceeded to sit there with a stupid great grin on my face that just wouldn’t go away. It is all the above and the bass !!!. My speakers are not that great (B&W DM220) at the moment so I can only imagine what It will be like when I finish my Aksonics and do the Nirvana Upgrade.

 

Tore Martensson, Malmoe, Sweden  

Although my AKSA is new, my impression so far is that the 100W N+ amplifier is absolutely amazing. My AKSA 55 (stock) is good, but the 100W goes at least one step further.

I expect even better sonics when the electronics is thoroughly burned in. I am especially satisfied with the bass tones from the amp, just the way I like it. (October, 2005)
