Description

Il Synthesis Roma 510AC is a integrated tube amplifier Stereo designed and hand-assembled in Italy. It delivers 80 W RMS per channel into 6 Ohms, a high power output for a tube integrated amplifier, allowing it to drive even insensitive floorstanding speakers.

The final stage works in push-pull pentode with a pair of KT88 per channel, replaceable with 6550. At the input there is a double triode 12AX7 (ECC83), while a 12BH7 plays the role of inverter faseThe result is a dynamic and detailed sound, with a full midrange and a more controlled bass than you would expect from a hi-fi valve amplifier.

Operational silence is achieved on several fronts. All signal tubes have their filaments powered by stabilized DC , a solution that reduces hum to almost imperceptible levels. The high-quality ferrosilicon output transformers are attached to a very rigid frame, which limits the vibrations transmitted to the tubes.

Which tube amplifier should you choose for a system with multiple analog sources? Roma The 510AC offers five RCA line inputs, enough for a CD player, streamer, external DAC and separate phono preamp. The output pre-out It tracks the volume and allows you to connect an active subwoofer or a second power amplifier. Volume, mute, and input selection are controlled using the included remote control.

This is a line-only integrated amp: it doesn't have a phono input or the balanced XLR inputs found on the Signature version. Vinyl listeners will therefore need an external phono preamp.

About the brand

Synthesis is an Italian brand based in Morrovalle, in the province of Macerata, in the Marche region. Founded in 1992 by Luigi Lorenzon, it specializes in the production of handcrafted tube integrated amplifiers, power amplifiers, preamplifiers, CD-DAC players, and high-end hi-fi systems. The name Synthesis reflects the company's philosophy of a perfect synthesis between Italian valve tradition and advanced technological research, with the motto "Art in Music" expressing the intent to blend technology, design, and musical passion. Synthesis They stand out for their elegant and distinctive Italian design which combines fine metal and lacquered wood with visible valves, and for the excellent construction quality which derives from the experience inherited from the FASEL, a company founded by Luigi Lorenzon's father in the 60s for the production of transformers for professional music amplifiers.

What are DACs and Streamers and when are they really useful in Hi-Fi?

If you listen to music from Spotify, Tidal, or Qobuz through your computer or smartphone connected to your system, you've probably wondered if you're truly exploiting the potential of your speakers. DACs and streamers are the two digital components that…

What is a DAC and why does it exist?

DAC stands for Digital-to-Analog Converter. Its job is to transform the bits of a music file (the zeros and ones of the digital world) into an analog electrical signal that the amplifier can amplify and the speakers can reproduce.
