As things don’t stay in one place and whole universe is in the move ,it is not a surprise that we got some latest news from The Home of Absolutor as well . There are new version of this fantastic preamplifier available now. After trial period new preamp with a head amp on the board is available to customers now . The build in head amplifier is based on SE design ,which is an absolute rule with Mr. Absolutor. The valves employed in this design to hold the duty are well known and beloved EL 84 penthodes.
Please have a quick look on final trial units.Pictures show inside and back of the regular balanced Pre and Head amp equipped units for the best comparison.
Amplifier offers mighty 8 Watts of power per channel ,hence additionally had been equipped with speaker terminals ,to be used as a full functional integrated amp for high efficiency speaker units. Amp shares the same double chassis as regular Absolutor preamplifier .Recommended sensitivity is 90db and more ,so all single driver and horn designs apply . But some dynamic spkrs doing equally well with this amplifier. For example our own Hurricanes from Cube Audio sounded great on listening tests with Absolutor amplifier with absolutely no driving issues.
Suggested manufacturer price for this model is £ 3.200
The lampizatOr DAC generation 4
-by Lukasz Fikus
High End – Hand Made in Poland
What I offer you is my time, talent, experience and passion to build the most exciting DAC today known to me ! We are an established company, with two facilities for manufacturing and a team of 6 people.
I have arrived at the Lampizator 4th generation DAC though a lengthy process. 8 years of everyday testing different DAC chips – over 100 conversion chips tested with the same lampizator circuit to hold the analog part as constant, practically all available chips have been tested. I have narrowed down the choice of dac chips to just 5 and then I used 4 different types of digital receiver chips and tested them with DACS in all kinds of permutations. In the end, the selected “couple” was subjected to tests of various operating modes, clock frequencies, sampling rates, oversampling, upsampling, and other options.
This stage was the longest and most challenging because the circuit of the digital part is extremely sensitive to even the smallest variations, and there are countless traps and problems.
Putting my reputation on the table, I do believe that the 4th generation DAC is a very musical, transparent and analog- like product. I sell it in the worlds’ most competitive market and so far the reviews are enthusiastic.
The sound quality of my DAC is already on another level, compared with my earlier DIY projects like Lampucera,Behringer and Buffalo. Customers across the globe are very satisfied.
DAC Generations and levels:
The generation number means a significant step in improving the DAC technology and sound. Gen 1 was a prototype, Gen 2 is a more mature and stable design. Since its introduction in July 2010 I made some progress, qualifying for the title of Gen 2,5. Namely I upgraded the dac microchip to the newest 2010 model with 32 bit resolution and upsampling. Second improvement is a discovery of new caps for digital section which surpass the oscons, blackgates, tantalums and MKP’s. They contribute to the ultra transparent and pure sound. Third is the employment of new lampizator output scheme – differential summator. It utilizes the balanced differential DAC outputs and it takes the very good sound to awesome level. All the improvements combined – starting from October 1 2010 result in a major step forward towards the best sound in the world.
We started shipping out Gen4 DACs starting from march 2012, yet without formal announcement.
Serial numbers 205 and higher are Generation 4 already.
Currently we ship Generation 4 DAC on 4 quality levels.
The levels simply reflect the technological sophistication versus the retail price.
Some technical overview:
I use the best D/A chip known to me and selected from all the World’s DACs by endless tests. The generation 4 digital PCB is a fixed project. It took 6 years of everyday testing to arrive at this PCB design so it is very unlikely to change by much anytime soon. The design is NOT based on any known product; it is not even loosely inspired by any kit or DAC. It is a genuine original design, based on chips previously not used together and in a configuration un- tried before . The chips are current production, latest models and not nostalgic 16 bit units. It is a multi bit top model with fully differential balanced outputs and 192 kHz capability.
I pay fanatical attention to the analog stage, using tubes and no silicon. No op-amps. Purity and simplicity of single ended triode amplifier between the DAC and the output is one of the key ingredients.
I designed and engineered the box from the ground up to be a unique and quite handsome housing: your choice of silver or black faceplate. What is common is the lampizatOr’s ring LED button and the tubes being mounted upside-down under the “belly” of the DAC.
You can order from options like multiple dig inputs, XLR balanced outputs, Tos-Link, volume control with remote, Preamp functionality with inputs, one of the best if not THE best USB solution on the market. (32 bit asynchroneous and up to 380 kHz)
From Level 3 and up – I build a tubed power supply which is at least 400% oversized to provide the unheard of purity, authority and grunt. Every supply has built in both 230 V and 115 V windings. All GND is star topology. Everything, except the tubes is stone cold. In Level 4 and 5 the power supply is electrolyte-less. In Level 5 the power supply is also fully dual mono.
The use of approx. 10 times oversized capacitor bank effectively means that the DAC board as well as tube anodes are supplied by caps for 3 minutes of operation without need to recharge. This is a quasi battery operation but without the hassle of real batteries charging. The lampizatOr DAC does not “see” at all the AC influence, its quality, fluctuations etc. The custom made massive chokes separate the electronics from any AC residual history and the Fikus Power Supply is as pure as it gets. You can hear that, let me tell you.
Everything is made by hand by myself or my 6 employees. The process takes 3 full days of preparations, assembly, testing, burn-in and music listening in my Nirvana system. Every unit is numbered and documented. Nothing is outsourced except metal work.
I use parts of MY CHOICE and I make absolutely no apologies for it. I don’t accept any pressure to change the parts to any other than my own. All parts are over-specified, usually old stock, mostly military, preferably Soviet made or Warsaw Pact. (Disarmament is a part of my mission). Remember – every lampizatOr DAC or kit – means that ONE MORE missile or MIG is grounded. “Make Mozart, not Nukes !”
V-Cap Copper and Jensen Copper caps are available at extra price.
I offer 7 days comfort of a full money refund for testing (excl. shipping cost) counting from the day you receive it.
I offer 5 years warranty for parts and labour excl. tubes.
I already got these news from Lukasz and I am pleased to announce that, as it took some time to happen, that GM 70 valve based amps Mr. Lampizator was working on for a while now passed all tests and are just about to be launched. Only some finishing touches are necessary to match an appearance of DAC and TranspOrt units and I will be proud to offer first pair for an audition.
Expected retail price for a pair is 5.000 Euro.
Please take a quick first look at the prototype :
Here we have got some technical highlights :
*Three separate transformers, 800 watts in total.
*Fourth speaker transformer sourced from Israel with ultra thin laminated audio grade steel.
*Choke supplies for big tube and for small ones too.
*Tube rectification for small tubes and for big one as well, separately.
*Manual bias by a pot with analog meter installed.
*ECC88 input tube and 6N6P driver tube in paralleled cathode follower mode.
*Silver point to point wiring.
*8 Ohm output matching
*Output power : 30 Watt max
*30 kg weight per monoblock.
As it is always an issue with Lukasz ,he managed to step forward again and offer to the customers whole range of bespoken DAC units available ,depended on customer taste and personal choice only. Here are some pricipias of the offer pointed below with rough price guide too. So here we have just a few ideas – others can be always discussed ;-]
PRICES: prices are negotiable, depending on request. As a guidance 15% of list price will be added, depending on the Level of the DAC.
Following Albedo interconnets had been restocked:
Beginning ,Flat One ,Geo .
Please ,contact us for a loaner or demo.
I have been waiting a moment fo Human Audio TABLA digital interface review to come and complete the MUTO DAC one .Now they are both published ,so it is time to announce an introductory sale for those in agreement with HA sales department . It should help to set up a modern source for all of us who are using computer unit as an exclusive sound source to get the best possible for the money. HERE we have TWO excellent intro offers then ;- ]
Both ,Tabla and Tabla Pico are basicaly the same units.The only difference is that the pico one sports smaller box which can accomodate only one battery ,when “big” Tabla has two and sharing design with Muto Dac making them perfect matching pair for those who want to keep it neat. A battery run time is same then ,when pico offers only half of Muto run time. Please go for all technical details to Human Audio web site. Any questions ,please ask about on phone or email. We will answer all enquiries as soon as possible ,txs ; – ]
AN OFFER IS FINISHED NOW. THANK YOU ALL WHO TOOK A PART OF IT ; ]
