PLEASE NOTE: The Lusso will be discontinued by January 2018. Taking the place of our top reference preamp will be the Verita, a single chassis, single power supply version of the Lusso.
The Lusso series preamplifier is a twin chassis design featuring a matching external, dual mono solid state or vacuum tube power supply to further guarantee interference-free performance. True Dual-Mono design. Each of the two channels operates completely independent of the other. Each channel has its own choke filtered power supply included a dedicated, highly regulated DC supply for each of the two tubes.
The Lusso is specially designed for devoted high-end audiophiles who want nothing but the best. With the use of highest quality parts and components, the Lusso is simply the best preamplifier that we have ever built and a true contender for any <$20K preamplifier.
The Musica Bella preamp models are quickly becoming known as having exceptional performance to price ratio. What you are getting is a custom "built-for-you" true reference level, Class A tube preamplifier at direct from the manufacture prices.
The Musica Bella Lusso linestage is a true reference quality linestage that was brought forth to provide reference quality performance at factory direct pricing. All units are custom built to order. The Lusso is voiced to offer solid state speed with vacuum tube soul. Bass is deep, tight, fast and authoritative with just the right balance of body and warmth from the Class A tube stage. A clean, crisp yet lively midrange and upper end with an uncanny sense of air and detail brings emotion back to your listening experience. The use of quality components throughout allows for a great sense of detail, transparency and resolution while maintaining the musical purity true music lovers lust for.
The gain stage circuit is based on a single 12AU7 or 6922 tube per channel and is designed with a constant current source topology. Signal path components include high precision Carbon Film resistors, DynamiCap output capacitors feeding balanced output transformers that provide transformer coupling for both balanced and single ended outputs and high quality cryogenically treated silver plated copper signal wiring with Teflon dielectric. Balanced input transformers provide transformer coupling for both XLR balanced and RCA single ended inputs. A GoldPoint step attenuator is optional
Front panel options: The Lusso comes equipped with a few options. HT Bypass, Stereo/Mono, Tape Monitor and High/Low Gain. While some may desire these options to fit into their system configuration, there are many, including myself, that do not need or want the extra circuitry. You can choose to keep or leave out any combination of these options for a more pure signal.
Remote Volume w/Mute
This includes a high quality motorized volume control. The driver board also has Mute function. A complete, dedicated power supply is used including a dedicated transformer to keep the remote system completely isolated from the circuit's power supply.
A high quality relay based selector board is used and receives its own dedicated power supply.
The Lusso's noise floor is exceedingly low due to our well thought out choke filtered power supplies which helps it uncover the lowest level of detail in a way that's unmatched in any product in it's price range. Coupled with this is a very forceful, immediate presentation that makes for exceedingly wide dynamic range. There is also a forcefulness, especially in the bass, which has great depth, power and speed, that will have you pulling out some of your favorite recordings, whether is be digital or vinyl, just to hear what emotions the artist was truly trying to portray.
The low output impedance of the Lusso allows it to drive most any solid state and tube amplifiers. The versatility of Musica Bella preamplifiers make them suitable for any amplifier, both solid state or tube.

Within the power supply chassis there are two separate twin choke filtered power supplies. Each with it's own high current toroidal transformer, 10 pieces of polypropylene filter capacitor (20 pieces total) and 2 chokes (4 pieces total). Fairchild 8A/1200V Ultra Fast diodes.
Each tube has its own highly regulated DC filament supply.
Why so much polypropylene in the power supply? Found in the power supplies in almost all audio equipment use electrolytic capacitors, the worst quality capacitor made today. So why do they use them? Simple....size and cost. Electrolytic capacitors are small and cheap. Often time, an electrolytic power supply can be 1/10th the size and cost of the same design utilizing polypropylene capacitors.
OK... so why are polypropylene capacitors better in tube audio components? A polypropylene capacitor discharges faster and more completely than an electrolytic capacitor. What this does is to make reserve power more immediately available providing lightning fast speed and dynamic control. This allows for tighter and faster control throughout the entire frequency range.
Standard chassis' are 1/8" black anodized brushed aluminum. 16" W x 10" D x 4.25" H
