This chart (based on using MM inputs with 47k Ohms impedance setting on phono stage) is not accurate for Denon Cartridges.
Note: Where 2 numbers appear, either can be used.
Why would you buy a step-up transformer instead of just sticking with a high-gain phono preamp? Because, with exceptions, transformers offer better sound--providing more drama, more color, and, especially, greater touch and impact.
The CineMag Mono features newly designed ultra high quality laminations, lower inductance and superior sound! The transformers for the CineMag Mono SUT were specially designed and tested with several low-output moving coil cartridges. These are very difficult transformers to construct and require a precision manufacturing process that can only be done by David Geren at CineMag.
These specially designed transformers are wired to connect a mono moving coil cartridge (on a turntable) to a phono preamplifier, phono input of a receiver, or your preamp's phono input. The Mono is switchable for 1:10 (LOW) or 1:20 (HIGH).
The grander point, of course, is this: If you own an Ortofon SPU or similar low-output MC cartridge and you're looking for a giant-slayer of a step-up transformer, this may be the product you've been waiting for. The Bob's Devices Sky 40 won't make serious phonophiles forget all about the Hommage T1--or the Audio Note AN-S8, or the Western Electric 618B, or any of the other transformers that might lay claim to the title The Best--but it will give hobbyists of less-than-extravagant means a chance to wring even more enjoyment from their favorite records.
In listening to the Cinemag Sky 30, I was distinctly aware that this device is not an emotional instrument. It is, rather, a transparent, analytical, and musical device that reveals a tremendous amount of information in the details of a recording. The Cinemag Sky 30 is extraordinarily good at opening up a soundstage and placing instruments within that space with a clear sense of the air around them. Imaging, detail retrieval, intimacy, resolution are all qualities the Cinemag Sky 30 has in spades. With multiple versions (Sky 20 and 30), it offers versatility for use with many different cartridges and phono stages....I would highly recommend Bob's Devices Cinemag Sky 30 if you have the budget to accommodate it within your overall financial allocation.
All connections are Resistance soldered using the American Beauty system which avoids heat damage to the delicate insulation on the hair-like wires of the transformers. Test equipment is very low current to avoid saturating the transformer cores. You can count on a premier product that is state-of-the-art.
This unit includes a grounding post that can be used to connect your turntable ground and your preamplifier ground. It also includes a ground "lift" switch. In all modes, the transformer cases and faraday shield internal to the transformers are connected to the ground screw. In the "ground" mode, the phono system minus sides (negative sides) are connected to the grounding lug. This configuration works well for those systems where the turntable ground is connected to the negative leads coming from the phono cartridge or where the negative inputs to the preamp are internally connected to ground. In the "lift" mode, none of the conductors in the RCA jacks are connected to the case, ground, or shield and there is no electrical connection between channels. This design allows you much flexibility to mitigate for ground loops regardless of the configuration of your other equipment.
