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.

Nice Firm
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
So I don’t love this body pillow but I do like it. This is a great pillow for anything the only downside is that it’s super heavy. It’s not something you would throw around the house that’s for sure but it does do its job when I’m sleeping and need something in between my legs my knees. It’s nice and firm not floppy, it’s perfect for a body. It’s perfect height, I’m 5’4 so it is perfect length wise. If you’re looking for something fluffy and lightweight I wouldn’t suggest this pillow but if you’re looking for something you can use for say menstrual cramps or a bad back and simply just to have between your legs than this is the pillow you want. I recommend it to anyone who doesn’t mind a little weight while making your bed. I give it 8:10.

Love this pillow!
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
Love this pillow. I bought 2. No weird smell and the cover is half cooling and half bamboo. It is also removable so that it can be washed. The inner pillow insert has a thin permanent cover on it to keep the shredded memory foam enclosed, this is standard compared to other memory foam pillows I've bought in the past. I got them on a used like new discount, and they were still vaccum sealed and truly like new. I couldn't be happier with these pillows, I am so glad I got 2.

So Comfy
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
I'm obsessed with this pillow. Been looking for a good body pillow but could only find the kinds that have that polyester filled from the stores and usually they flatten out easily. But found this out and its filled with memory foam and the casing has a nice cotton feel and the other side is a cooling side which I love. Its so comfortable and can easy be reshaped back from the memory foam. It's worth it.

Wish it was more “cooling”
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
The pillow is somewhat comfortable, I don’t find it “cooling” it does hold its shape and it gets really fluffy. I am a hot sleeper I was hoping it would help with the cooling but I find it no different than any of the other body pillow’s I have bought
