SUTHERLAND

SUTHERLAND - puritatea simplitatii si esenta designului unui produs cu sunet natural.
Fabricate in Statele Unite, phono stage-urile SUTHERLAND au cucerit rand pe rand
pietele din USA, Asia si Europa.
Renumite pentru naturaletea sunetului si adaptabilitatea la orice tip de doza si pick-up,
uimesc prin simplitatea designului exterior si extraordinara calitate interioara atat a
componentelor folosite cat si a viziunii castigatoare in asezarea lor.

Ron Sutherland, nimeni altul decat inventatorul si fostul proprietar al Martin Logan,
este unul din primele 3 nume grele la nivel mondial atunci cand vine vorba de desen,
inovatie si sunet aferent phono stage in general.

Incepand cu 1 Martie 2014, STEREO PLANET ESTE ONORAT SA AIBA UN ASEMENEA
PARTENER ILUSTRU, IN EXCLUSIVITATE, CUM V-AM OBISNUIT.

The short story is:
The Sutherland DUO MM/MC Phono Stage is derived from the cost no object Sutherland Phono Block
and the cost-optimized 20/20 Phono Stages.

The long story is:
No expense was spared in the design and construction of the Sutherland Phono Block Phono Stage.
The Phono Block is at the pinnacle of phono preamp performance! It just doesn't get any better.
The Sutherland 20/20 MM/MC Phono Stage was designed to get the most performance possible at its
predetermined price point.
To get there, extra was spent to get premium parts and circuitry into the signal path.
Consequently, some expenses were squeezed out of less important areas.
Those trade-offs have worked very well.
The 20/20 has delivered an extremely high level of performance at a reasonable price and is an incredible performance value.

What if all the price constraints in the Sutherland 20/20 MM/MC Phono Stage were lifted?
The price goes up, the performance goes up.
The 20/20 starts looking a lot like the Sutherland Phono Block.
The actual signal path of the 20/20 is quite good.
It uses a circuit very similar to the Phono Block.
In critical positions, it also uses the same premium quality (and high cost) components.
Very little was held back in that area.
The opportunity for upgrade is focused on a more refined power supply, improved circuit board
properties and dual chassis construction.

Power Supply:
The Sutherland 20/20 uses external, bench-top power supplies.
They are cost effective, reliable and offer good performance.
Each supplies output is extensively filtered and regulated into one +/- 15 volt source for both of the gain stages.
The Sutherland Phono Block has built in AC power supplies.
There is an IEC power inlet on each chassis to accommodate the user's personal power cord choice.
Two completely separate power sections (each providing isolated +/- 15 volts) are provided for each channel.
One for each of the two gain stages.
Each is independently filtered and regulated to provide the ultimate foundation for the gain stages.
Each Sutherland DUO MM/MC Phono Stage has a built in AC power supply.
There is an IEC power inlet on each chassis to accommodate the user's personal power cord choice.
The shielded power supply module has one output.
That output is split into two branches.
One for each of the two gain stages.
Each of those branches is independently filtered and regulated to provide a substantial foundation for the gain stages.

Circuit board properties:
Circuit board dielectric properties can introduce detail damaging artifacts into the signal.
The Sutherland DUO MM/MC Phono Stage mitigates circuit board dielectric properties using the same
approach that has worked so well in the Phono Blocks.
Circuit board thickness is doubled from the standard 1/16" thickness to 1/8" thickness.
Not only is dielectric absorption addressed, but further advantages are realized with an extremity rigid
platform for component mounting. It is the cost-no-object, preferred way to go.

Discussion:
Anytime two conductors are at a different voltage potential, there is an electric field generated between them.
The dielectric (the insulation between conductors) within that field become involved in charge storage.
If not carefully considered, that extra charge storage can time smear details of a musical signal.
Circuit board material is a dielectric.
With normal double-sided construction, there are copper conductors on each side of the board.
Unintentionally, a new capacitor is introduced into the circuit, formed by top surface copper, bottom surface
copper and the circuit board dielectric sandwiched between the two.
It is NOT the quality of capacitor we want to have in a high-end signal path.
Some manufactures make the situation even worse by going to multi-layer boards in the analog audio sections.
Instead of two layers of copper, there are four or more layers of copper.
Even worse than that, the dielectric between layers is much thinner and the undesired capacitive effect is
inversely proportional to thickness.
At best, some manufactures make small, incremental improvements by using exotic board material.

The Sutherland DUO MM/MC Phono Stage addresses the issue of circuit board dielectric by doubling the
thickness of an FR4 fiberglass circuit board.
Just that one choice reduces electric field strength by one-half.
Additionally, the area of copper interacting with board dielectric is also reduced in critical regions.
Signal lines are kept narrow.
Power lines are extremely wide.
Such choices get us refined performance.
Good solid advantages based up the application of good solid physics.

Dual chassis construction:
A sense of space and dimensionality is conveyed by the difference in the left and right channel information.
To preserve those auditory clues, each channel must be isolated from the other and not spill over.
Both the Sutherland DUO MM/MC Phono Stage and the Sutherland Phono Block use a stack of two mono phono
preamps for stereo.
Absolutely nothing is shared between the left and right channels.
Each channel is a completely free standing mono phono preamp.
That is the ultimate in channel separation.
The ultimate in spatial listening involvement.
