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.

Powerful easy to operate but splashes
Color: Black
Excellent frother--Very powerful and easy to turn on/off with one button. The only downside is it requires a deep container in which to froth. The frothing pitcher I had was too small and milk splashes everywhere. There is no lower speed so it works fast. I am using a deep insulated container now for frothing. Otherwise, very quite, easy to operate no pushing down on the top like other frother wands. I love it as long as I can control it to limit the splashing.

Froths Milk in Seconds
Color: Black
Frother I had for a couple of years broke. Based on reviews I bought this. Love it being rechargable. The POWER! It froths milk in seconds. Also great for that after workout protein drink. Also is a little longer than my last frother so it works great with larger glasses.

Best kitchen device!!
Color: Black, Color: Black
This frother is absolutely amazing such power behind it . Quality is just as amazing made very rugged. And I love the stand and the best thing about it is no more batteries to change now we just charge it up. I HIGHLY RECOMMEND this product to everyone and I will be buying more of these for gifts and more for our winter home also. You won’t be disappointed at all.

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds. I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges. Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.
