Fixed Gain Pre - Booster Box

The newest addition to our Black Box series of products is the fixed gain preamp otherwise know as a booster box.

Although many Digital Audio Players and DACs claim 2volts RMS out, measurement of their sustained output shows them considerably less. By utilizing the Booster Box we are able to get the analog output of a DAC/DAP to true line levels with significant performance improvements as a result. 

Think of this as a full fledge preamp without the volume control. Gain is modest at 2.2 but in practical terms this means a 800mv output from a USB DAC is boosted to 2V and your tube headphone amp has the input with dynamic headphone. 

At ampsandound we try to build bespoke products that are purest in execution. As a result, all our headphone amps have volume control, the booster box is the perfect companion allowing Your amp to reach its fullest potential. 

Single ended, single gain stage tube amps love robust/hot front ends and digital sources rarely provide the voltage swing, this box is meant to solve this problem. 

In short, add your DAP or your entry level DAC and you'll be blown away but what's possible when coupled to a true analog pre. 

The circuit is simple, right out the NEC Op and manual, the magic comes from pairing a linear regulated PS and an over specified power transformer with great regulation. Rock solid power supply and modest gain equates to ultra-wide bandwidth and low noise floor.

Very nice style and material
Color: Maple Leaf Wf157, Size: X-Large, Color: Maple Leaf Wf157, Size: X-Large
This top fit perfectly. I liked the v-neck. The material was so nice -- a tiny bit silky and not clingy. I loved the colors too. But I returned it, because for me (and I know this is really picky), the leaves and flowers were too big for my liking. I felt old in it.

Comfortable
Size: 8, Color: Natural Snake
These shoes are cute, and go with most everything. They are comfortable and can be work for while without having any issues. I was a bit worried they might rub blisters but have not had that problem with these. The heel and fit of them are perfect. And they are versatile. Worth the price.

Small toe box BUT SOO cute
Size: 8.5, Color: Natural Snake
Very cute but if you have wide toes and typically require a wider toe box you’ll end up with blisters if you walk a lot in them.

Cute but uncomfortable
Size: 6.5, Color: Black Leather
I’m usually a size 6. I got a 6.5, they fit perfect. Super cute, but just from trying them on and walking around my fit we’re already turned red. Still going to wear them to my event but I’m in for one lol

Comfy and perfect heels for the summer!
Size: 8.5, Color: Chestnut Suede, Size: 8.5, Color: Chestnut Suede
Love these heels! I’m 5’5”, 120 lbs and size 8.5. They were comfortable from the moment I put them on and I have somewhat wide feet. They are the perfect summer heels!
