With the Sunilda, Audio Valve is building some of the finest and affordable tubed products available. The Sunilda is a great example. Loaded with features, beautiful sonics, and a price that makes this phono stage a veritable bargain in the context of its' competition. The Sunilda uses two 12AX7 and 6922 each making it a tube roller's delight.

Inputs for 2 MC or 2 MM cartridges at the same time; ideal for the enthusiast with a 2 tables or a table with dual tonearms. Front panel controls for loading and capacitance. External power supply for superior isolation and on and on. The Sunilda is one terrific value.

Sundila is a three stage phono-preamplifier, based on 6922 (ECC88) and  12AX7 (ECC83) frame grid tubes, suitable for two MM- and MC-cartridges at the same time. Independently for the two phono inputs, impedance and capacitive load can be set separately and 'on-the -fly' while listening. Thus the user can easily configure the unit to match the features of the cartridge by selecting the optimal input resistance and capacitance for each input separately!

A view of the compact and absolute wireless electronic - RIAA module from SUNILDA. There is no hum, bee or any noise - only music. The design on a double side pc board is constructed in double mono technology, use best and selected components and guarantee high stable and high-end vinyl re-productions.

Switches in front are found for: MM/MC mode for each input; input 1 or 2; selectors are used to select different resistor and capacitive input loads.

In MM mode the gain will be 23 dB lower than MC and at a fixed input-impedance of 47 K.

In MC mode the preamp will have 20 dB higher gain and switchable input resistors and condensers. The RIAA de-emphasis is passive and split between the first and second stage. Dividing the RIAA network over two amplification stages lowers the insertion losses of the passive network dramatically. Furthermore, the design holds a total absence of feedback, thus increasing the overall dynamics.

Power supplies are solid state regulated. This is the best way to obtain a low noise and supply line with a very low impedance that will increase the performance in the lower frequency range. The power transformer is housed in a separate aluminum case.

Sunilda comes in an laser cut, 3mm thick steel, chassis in black or silver finish and has a case similar to the Eclipse line-amplifier. It is, therefore, physically impressive for a phono stage in terms of bulk and heft.

Audio Valve Sunilda Mainboard

With the beginning of Autumn 2013 Audio Valve launched a new improved version of the SUNILDA phono stage. Mr. Becker - the designer - had the desire to increase the musical and technical features with some realy interesting improvements almost into perfection.

The complete layout has been re-designed and overworked with the following impovements :

First of all the 2 copper sides - bottom and top - the layer thickness increased to 0.1mm on each side. Thus, significantly reduces the resistance per unit area on the PC board and little "power islands" on the main PC board can't built up any more.

At all measured points on the PC board you will find a realistic potential of 0 Ohm.

The total ground level of the PC board became more homogeneous, and so disruptive external influences will have no chance.

But we wanted to have the copper of the PC board even thicker. To reach this we used a special technical feature, called the "MULTI VIAS". By the help of the "MULI VIAS", which connects the top side with the bottom side , we doubled the thickness of the copper again, almost as if the PC board would have been built out of one complete piece of copper.

Another positive feature of this new PC board is the simultaneous improvement of the shielding effect against any kind of disturbing electromagnetic fields. Also the s/n ratio is improved so that any electromagnetic interferences or stray power supply currents will be completly absorbed. We are sure, that in the near future also our " NEW" Sunilda will find its place in the TOP Class of High-End.

The screen from the Oscilloscope show you the maximum produced noice from the amp in the MC mode - its an absolute fantastic result for a tube phono pre amp.No hum no bee - simply nothing to hear any ground basics noises. It's AudioValve's SUNILDA!

"...Germany's AudioValve is building some of the finest and affordable tubed products available today. The Sunilda is a great example. Loaded with features, beautiful sonics, and a price that makes this phono stage a veritable bargain in the context of its' competition. The Sunilda uses 2 (two) 12AX7 and 6922 each making it a tube roller's delight. Personally, I've used Telefunken, Siemens, Mullard, Amperex, and RCA among others. The many different combinations of tubes make for an unlimited number of possibilities you might find satisfying. I've been listening your Sunilda you'll be hard pressed to buy more for its' price and perhaps even a couple thousand more. Inputs for 2 MC or 2 MM cartridges at the same time; ideal for the enthusiast with a 2 tables or a table with dual tonearms. Front panel controls for loading and capacitance. External power supply for superior isolation and on and on. The Sunilda is one terrific value...."

"...the AudioValve Sunilda is one of the most enjoyably tube-based phono preamps I’ve heard..."

Ken Kessler for Hi-Fi News:
"...the Sunilda pours forth the detail, the air, the sense of a 3-D space and the kind of control that's hard to fault..."

"...as you can imagine, competition in this sector is tough: really tough. I recently bought the AR PH5, and - love it though I truly do - I have to admit that it's shy of adjustability, and lacks the facility for a second turntable; this makes a pain in the arse if you like to fiddle about with cartridges and decks. Conversely, it's the choice if you don't fiddle around. EAR's phono offerings are always magical, from the least expensive to the sublimely dear; Quad's new valve phono amp is even more of a bargain than the Sunilda; Sutherland's PhD is the quitest phono stage I've ever heard. AS any show-goer will tell you, there are countless other superb phono amps to consider as well. The Sunilda however is genuienly special. It manages the combine the best balance of all of the above phono amps' virtues, sonically and practically, then doubles them up and sells them to you for a sane price...."
