MAKUA Pre with Tambaqui DAC

We have a traded back Makua Pre-amp with the Tambaqui DAC for sale. This is a one owner Makua/Tambaqui that I originally sold when new and it is excellent condition. It comes with all originally casing and boxing so can be shipped interstate. Australian Shipping is included in the asking price.

These Makua's don't come up very often as most are purchased by discerning Audiophiles as their end game Pre/DAC and for good reason. One has to spend a significant amount more to even come close to find a dollar Pre/DAC that is even close to this Pre/DAC combo.

This unit is priced well below RRP and there is the option through us of sending it back to the factory to have the much acclaimed Phono Stage fitted.

 for those who know how good Class D amps can be I will soon also have a pair of the very rare in Australia demo Mola Mola Kaluga 400w Mono-blocks for sale.

If you are interested in this Makua please either message or call me on 0419448452.

cheers,

Terry

Mola Mola components are now available in Queensland and Northern NSW, please call Terry at GC HiFi on 0419448452 to discuss the various models we have in stock or to arrange a private demo.

ANALOGUE DESIGN FOR A DIGITAL AGE

With the knowledge in hand to design minimally invasive electronics without needing to be minimalist, Mola Mola decided that their preamp should be complete. Very complete.

Finally Mola Mola Amplifiers, Dacs and Pre-amps including the Makua are available for audition on the Gold Coast, please contact us at GC HiFi to arrange a private listening session.

The basic Makua is an extremely transparent gain stage and a programmable routing matrix. The chassis has ample room to fit optional extras, most notably a DAC and a phono stage. The 6 preset buttons are programmable via USB or Bluetooth to access any combination of channel, processing and routing. In a system with mainly digital sources, the preset buttons would be programmed to select between them. Vinyl lovers on the other hand might want to use several buttons to select the same turntable but with different EQ settings to suit their large collection of historic LP's. All five inputs are switchable between XLR and floating RCA connections, and all can be assigned as either phono or line.

All stages in the Makua use discrete amplifier modules in a little known topology called “single-ended driven differential”. Compared to doubly executed signal paths, this structure prevents noise from propagating all the way through. The Makua is amazingly immune to influences like mains quality and choice of interlinks. The relay-based volume control directly controls the gain of the output stage. Dynamic range and linearity of this arrangement is much greater than those of stepped attenuators. Operation is smooth and entirely glitch free.

THE MOLA-MOLA MAKUA DAC: FUTURE-PROOF BY BEING FAR AHEAD.

You probably know the frustration of discovering your DAC has suddenly gone out of date because some new super chip has hit the market. Mola-Mola decided to stay out of that cycle and design, from the ground up, a discrete DAC whose unbeatable staying power results simply from being more than 10 years ahead of the performance curve. There's room enough for improvement: today’s best DAC chip claims no better than 22 bits’ worth of dynamic range and only 20 bits’ worth of linearity. High resolution music deserves better than that. Mola-Mola’s DAC is designed from the ground up using circuits and digital algorithms that were entirely developed in house.

The converter is a three board stack that fits in one of the option slots in the preamp. On the first board, all incoming digital audio is upsampled to 3.125MHz/32 bits and converted to noise shaped PWM. The two remaining boards are mono DACs, in which a discrete 32-stage FIR DAC and a single-stage 4th order filtering I/V converter convert the PWM into analogue with a breathtaking 140dB SNR. This is near the theoretical limit for 24-bit files and far beyond that of even quad-speed DSD. Uniquely, distortion remains below the noise floor even for full scale signals. A quick look at current and historic trends of high-end IC’s indicates that for the foreseeable future this kind of performance will remain unavailable to manufacturers forced to rely on the same “chip du jour” that also powers their competitors’ products.

Even by today’s exacting standards, extraordinary care has been taken deal with jitter. Mola-Mola’s DAC uses a home-grown asynchronous upsampling algorithm whose input frequency measurement slows down rapidly until after a few seconds of lock, the frequency ratio measurement is frozen. Frequency stability is then wholly determined by the internal clock, a laboratory grade 100MHz SC-cut oscillator. This is effectively an atomic clock sans the physics package (which contributes nothing to spectral purity but quite a lot to cost).
