Spirito 2A3 Linestage

The Spirito linestage is meticulously crafted for discerning music aficionados who value simplicity without unnecessary features. The Foundation Spirito 2A3 prioritizes pure auditory delight, utilizing high-quality components that immerse you in the essence of the music.  

There are now a few Directly Heated Triode preamplifiers available today from exceptional manufacturers. However, these pieces usually carry a heavy price tag of $15k-$20k or more. Milled aluminum chassis, advanced digital technologies, and rare NOS tubes look and sound amazing.

Musica Bella is here to provide you with that DHT sound without all the bells and whistles or the big price tag. 

We have integrated new technologies into our tube products to ensure a smooth and noise-free listening experience, characterized by the alluring warmth of a Directly Heated Triode (DHT) tube. The 2A3 tube sockets are secured using Vibration Isolating Shock Absorbers mounted on the chassis, reinforced with solid brass standoffs to enhance stability.   

Additionally, the input board for the 6SN7 tube benefits from similar Vibration Isolating Shock Absorbers, ensuring optimal performance. The power supply board is also mounted securely to the chassis with these innovative shock absorbers.  

To address electromagnetic interference (EMI) and electrostatic interference (EFI), we have implemented a combination of Faraday and copper shielding, further enhancing the overall performance and listening experience.

The chassis is all aluminum with aluminum front backing plate with a laser engraved acrylic front panel. The chassis itself uses extensive bracing to help eliminate any resonance from the chassis to get into the signal.
