There's a better way to think Industry 4.0! SUPRATEC Engineering combines human talent and technological expertise to improve production performance. This is expressed through the development of new technologies, the industrialization of new products, the integration of turnkey solutions. A SUPRATEC brand. The owner was unbelievable friendly and knowledgeable, he put on a lot of great music, from jazz to classical and everything sounded sublime, very realistic and also very impressive bass, the speakers he said was about 89db, not a brand I know much about but they sounded bigger than they looked, 2 x 6 inch drivers, seamed to go very low when.

The power supply sports a 5AR4 rectifier (GZ32/34/37 or 5V4G may substitute) and 5881s (or 6L6GCs or KT66s) drivers. The signal tubes for the mid/treble circuit are current production TJ 101D globes. Bass is handled by 6SN7s.

I've owned the Lipinski L-505 speakers with matching subs for must be 15 years now.

A newer version of them is still available, and this model is used in recording and mastering studios throughout the world. Highly sought after, and snapped up when they come on the market.
They were also very highly regarded in the audio world , a number of magazines gave them high ratings and awards. They weren't cheap, costing over $10,000 around 2000.Drivers Supratec
You'll notice the tweeter arrangement is phase compensated physically, with the tweeter set back from the front baffle and the foam 'steps' acting as a wave guide , and to help with diffraction.
The result of this is excellent phase performance, the best explanation of phase performance is that the better it is, the better the speaker disappears. Imaging becomes very precise and sound-staging is wide and 3 dimensional.
They are also very accurate, which explains their use in recording studios, but not in an analytical way, they are still very involving and very pleasant to listen to.
They really do disappear, leaving the music just as 'live' as you could hope to hear.
Phase coherence is something the Supratek tube preamplifiers are famous for, they bring a 'big' open sound , something they have been engineered for.
Quite a few years ago I built a special preamp for the Lipinski's.
It uses 6SN7 input driver tube and 71A DHT (directly heated triode) output tube. Transformer coupled output, and with direct coupling (no capacitor) between the 6SN7 and 71A. This is to increase the phase performance of the preamp.
It works very well, and enhances the overall performance of the system .
Also included in the preamp is a 24dB subwoofer crossover for the dual Lipinski 15' subwoofers under each speaker. Of course it is tube based, using 4 x 7N7 tubes.
The crossover frequency is 70Hz, the Lipinskis speakers have good bass , so the subs are only required for low bass use.
They are non-boomy, and articulate, yet have good depth and power.
The preamp is quite old and quite ugly now, but circuit wise it's as good as new , and it is still a very good up to date design with the fabulous DHT sound. The 71A DHT tube is one of my favorite tubes. Seperate over-engineered power supply.

I've partnered the preamp with a Parasound 4 channel high current amp , 2 channels for the speakers and two channels for the subs.
There are level controls on preamp and amp to adjust balance of speaker/subs.
The Parasound is an excellent DC coupled amp, which again helps with the phase response of system.
The complete system sounds as you'd expect- world class audio components that combine to make a very synergistic , and capable sound. Extremely musical, foot-tapping , and hard to turn off!

In order to complete the package I'm including a quality Geek Pulse PCM/DSD dac, with optional power supply , and a simple mini-pc based music server with hard drive- everything you need to get going.

Free lifetime service on the preamp, but not on other components. However they are all well engineered, quality components and will last forever.
