The PrimaLuna ProLogue Three

"..Âm thanh của ProLogue 3 hoành tráng đúng với nghĩa đen .."
Ken Kessler Hi-fi News

The 3000 usd preamp for those that don’t want to spend 3000 usd !! Think we’re kidding? We want you to study it carefully. Let’s look at the ARC LS-16 mkII which weighs in at 11.9lbs and is not dual mono, and uses circuit boards, all for 3495 us.
The ProLogue Three is true dual mono with 2 toroidal power transformers, choke-regulation, point to point wiring, and premium parts including an Alps Blue Velvet potentiometer and Solen and Swellong capacitors. Five coats of hand-rubbed finish, removable tube cage, and ceramic tube sockets. It weighs in at 23.5 lbs, almost 50% more than the 95 preamp and sells for less than 60% !!
But it’s not about money. (Well….maybe a little)
The glory of tubes will breathe life into your solid state amplifier. The ProLogue Three boasts tube rectification using TWO 5AR4 tubes, one for each channel. No negative feedback and no cathode followers for a vibrant midrange that creates the kind of three-dimensional soundstage rarely encountered. Running it with a tube amp? Perfect. You will get wide bandwidth and real bass and a top end that is not bitey, but goes on forever. If you have noise issues or use high-efficiency speakers you will love it because it is so quiet. Only 11.5dB of gain and the tube heaters are DC so it will be less picky of tube choices. The power supply is perfectly de-coupled with an ultra-wideband (several MHz) constant source impedance and low corner frequency of over two octaves below the audio bandwidth (4Hz).
The ProLogue Three is non-inverting, and has two pairs of outputs so you can easily bi-amp or add a powered subwoofer. Optional ProLogue Phonostage can be added at any time.
Available with optional MM phonostage.
