ΠΡΟΕΝΙΣΧΥΤΕΣ:
Classic 300 - US$2580
With continual improvements over the years, the Classic 300 has finally reached the stage where its performance is on par with that of the top model, DIVA M-7.
The Classic 300 sounds different, that's all. This is mainly because the Classic 300 uses 6SN7 tubes instead of 12AX7s in the M-7.
The main difference is the significantly lower price, from the use of partial circuit board, instead of point-to-point hard wiring throughout. This significantly reduces the amount of labour needed to build the preamp.
The Classic 300 comes with an external, solid-state rectifier power supply. (Note: Picture shows the wrong power supply, which should be just a small black box. A correct picture will be updated later.) Although less costly than a tube rectifier, this is NOT a cost-saving measure. The Classic 300 (and Classic One) circuitry favours a solid-state rectifier and this is confirmed by listening tests.
DIVA M-7 - US$2980
The DIVA M-7 is a replica of the the legendary Marantz-7 preamplifier, using 3 pieces of 12AX7 tubes, or equivalents such as the 5751 or the 8167.
This circuitry was developed during the 1950s. Yet no audio designer has since been able to improve on it All the great preamps in recent decades are either copies or variations of the Marantz-7. Hence Lims worry that he may not be able to improve on it either.
What Lim has done, however, was improve the implementation of this circuit by:
Greatly simplifying the circuit, removing unnecessary functions such as treble and bass controls, balance controls and so on, leaving only a volume control.
Paying careful attention to the mechanical aspects of amplifier design, such as chassis resonance and the centre-of-gravity. This is a secret unknown to the designers of the original Marantz 7 and still unknown to many audio designers today.
Careful selection of components to ensure that every component works in harmony with every other component.
Incorporating a separate tube-rectifier power supply with an over-sized transformer, for clean, pure power.
Employing full point-to-point hard wiring, doing away with circuit boards.
Most importantly, by using his set of very discerning golden ears to fine tune the preamplifier.
The result a vast improvement over a legend.
Do not hesitate to compare the DIVA M-7 with the most exhorbitantly priced preamps you can lay your hands on. Just be prepared for a rude shock! The DIVA M-7 is truly one of the best preamplifiers in this world.
DIVA phono preamplifiers feature a proprietory RIAA equalisation circuitry developed by T S Lim.
It's our trade secret. All we can say is that it is based on a very simple idea. And that it works extremely well, achieving near-perfect linearity across the entire audio spectrum.
The rest of the phono preamplifier continues the DIVA tradition of offering exceptional sound quality - the result of T S Lim's ingenious design, careful selection and matching of components and high quality craftsmanship with point-to-point hard wiring.
All DIVA phono preamplifiers come with a separate, solid-state rectifier power supply, using an excellent-sounding, European made rectifier. Our experiments with tube rectifiers suggest that they do not work as well in this circuitry.
Gain on the phono stage is high enough for moving magnet (MM) and high-output moving coil (MC) cartridges of down to 1.2 mV. (With a good-sounding phono preamplifier like the DIVA, it may not be necessary to buy costly, low-output MC cartridges. We have customers who achieve very good sound with relatively cheap MM cartridges.)
For lower-output cartridges, we provide a step-up transformer, custom-wound to T S Lim's specifications by a leading European transformer maker. This comes in a separate box, with Van den Hul connecting cables. We do not install an MM-MC switch as it badly affects sound quality.
