Musica Bella Harmonia Explained
What is the Harmonia
The Harmonia is not a buffer. A buffer stage is simply a zero gain (<1dB) Cathode Follower impedance matching device and can be tube or solid state. There are several applications where a buffer is beneficial to your system as it can add some tube richness to the presentation.
You can think of the Harmonia as a DHT source selector. This allows any source components hooked up to it to benefit from an active DHT (45,2A3,300B) stage, not a cathode follower, as the output stage.
Imagine your CD Player or DAC having a 300B/2A3 as the output tube.
Applications:
- Between source components and preamplifier (as shown below) with or without a volume control.
- Connected to the tape loop of a receiver (two channel or home theater), integrated amplifier or any device that has a pre-out/main-in with its own volume control.
- If equipped with a volume control, it can be used as a preamplifier but please note there is the potential for noise when connected directly to a power amplifier.
