Description

HC1 High Current Headphone AmpThe HC1 is an expandable, high powered headphone amp designed specifically for critical studio monitoring. The HC1's circuit employs parallel amp stages for greater power and lower distortion. This parallel opamp concept has been known in theory for decades and was put to practical use in Douglas Self's "5532 OpAmplifier" power amplifier. As a result, the HC1 sounds clean and clear even at high gain and when driving low impedance headphones. Because

The HC1 is an expandable, high-powered headphone amp designed specifically for critical studio monitoring.

The HC1's circuit employs parallel amp stages for greater power and lower distortion. This parallel-opamp concept has been known in theory for decades and was put to practical use in Douglas Self's "5532 OpAmplifier" power amplifier. As a result, the HC1 sounds clean and clear even at high gain and when driving low-impedance headphones.

Because everyone's monitoring needs are different, the HC1 is designed to be customized. The power and audio input connectors are screw terminals, so you can attach whichever jacks you need without soldering. You can also daisy chain multiple HC1s to make a multi-channel headphone amp.

The HC1 is a great project for intermediate builders who enjoy the challenge of choosing their own chassis and inputs.

Perfect suit for boys
Color: Navy Blue, Size: 12 Years, Color: Navy Blue, Size: 12 Years
So thankful for this! This suit was perfect! My son wore this all night playing and the durability of this fabric is on another level. Wasn't too thick, looked really nice, and fabric was really soft. It also blended really well with the suits from Mens Warehouse.

Perfect!
Color: Royal Blue, Size: 12 Years, Color: Royal Blue, Size: 12 Years
I was nervous about purchasing something like this at the last minute. But based on the previous reviews I decided to take a chance. The suit is nice and the material feels really good. Not thin or cheap at all. My son looked so handsome and grown up. He’s on the slim side so he does have extra room but I don’t mind it because he can definitely grow into it. I did purchase a separate tie because I wanted a pattern to complement the blue. I’d definitely purchase again!

Big in waist
Color: Grey, Size: 12 Years
Very nice suit, the material was nice. My son is an average build, the suit fit on the length but unfortunately the pants were huge in the waist. Even with the inside waist adjuster and a belt he couldn't wear them. Which was disappointing because overall the rest of the suit was perfect!

Perfect
Color: Royal Blue, Size: 8 Years
The tops fit perfectly however my 6 year old is very tall and slim so the pants were a little big but at least the adjustable straps on the inside will help..love the color
