Tube Amplification

This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components.

Versatile

You can connect two turntables at the same time & easily set everything on the front plate. Each input settings are stored in the memory. Large ranges from 40dB up to 65dB are possible. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your Hifi system, matching the volume levels accurately to other sources like CD players or streaming devices. Load impedance can be set continuously via potentiometer, a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust the impedance during playback and immediately assess the impact of different loading options. This is necessary to find just the right load impedance for your cartridge. No other manufacturers implement this feature in this extreme way.

B is for Balanced

Some turntables offer balanced or RCA outputs. Connect your turntable either with the 5-pin mini XLR cable or standard XLR cables & profit from the balanced signal transmission. Symmetrical, also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. The Tube Box DS3 B can extract the final musical information out of the +/- signals and remove all noise that was potentially added along the transmission. All components including tube output and polypropylene capacitors are audiophile grade and guarantee a breathtaking sound experience.

Peacock Blue
Size: 6.5x10ft, Color: Lake Blue
Not out yet because of weather, but it looks good, unusual point that some of the spokes according to the directions need to be put on yourself, but at least this way they not bent in box. Note when I bought it - it used the color Lake Blue but the picture was a Peacock Blue - I took the chance and it is a Peacock Blue- I would not call it Lake at all or sky or any of those colors. It worked out for me as it matches perfectly with my Peacock Blue cushions and other umbrellas, It defintiely seems like it is sturdy and the size looks as it should, it has a nice weight as i did open it in house to take a look, the material has a slight sheen which makes it appear a little different than my others, but not something most people would notice.

Attractive and seems like it will hold up
Size: 6.5x10ft, Color: Blue-Green Stripe
Seems sturdy enough. Tilt button is difficult to retract to straight, but maybe just my finger strength, or it will loosen up with time. The color of one of the stripes is off from the photo. I was hoping it was turquoise as shown in picture, but is actually a much deeper blue. Doesn't coordinate with my other patio colors like I hoped it would, but it will do.
