True Recreation Of A Studio Classic Revered For Warm And Balanced Tones

Balance & Character

The WA-251 is a true recreation of a studio classic revered for its warm and balanced tones. The WA-251 delivers the same sound profile of the original mic, easily considered to be one of the greatest condenser microphones ever created. Known for its natural, rich sound reproduction so often used on vocals and acoustic instruments, the original was used by a long list of legendary vocalists including Adele, Ariana Grande, John Legend, Neil Young, Stevie Wonder, and many more.

A Studio Favorite For Warmth & Depth

The WA-251 captures natural sound with controlled bass and smooth high-end - just like the vintage 251-style microphones. Looking at the frequency response, the WA-251 essentially has an “always-on” 50 Hz high pass filter. With most usable bass frequencies running from 60-250 Hz, the WA-251 is a great choice for capturing lows and mids that sound “tight” in the mix vs. muddy or boomy. The 5-10 kHz dip in cardioid mode smooths out the highs to deliver a smooth top end that never sounds harsh.

Like the original 251-style mic, the WA-251 includes all the features that deliver a complete and professional recording experience.

The WA-251 uses a true reproduction of the CK12-style capsule in the original 251 tube mic. Perfect for recordings where vintage vibe is a must.

Three polar patterns (cardioid, omni, and figure-8) give you a variety of options to choose how you want to capture sound and reject noise.

The WA-251 uses a premium 12AY7 vacuum tube to complement the CK12-style capsule for smooth tone and vintage warmth without harsh high end.

The custom USA-made CineMag transformer drives the bold sound captured by the capsule, delivering the tight lows, present mids, and smooth highs out of the WA-251 circuit.

CK12-Style Capsule

The all-brass CK12-style capsule provides the performance of the vintage original, by smoothing out the top-end and delivering a pleasing, rich tone to the transformer. Unlike later nylon iterations of this capsule, the WA-251 faithfully replicates the clear open top end of the original all-brass CK12 capsule.

Cinemag USA-Made Output Transformer

The WA-251 utilizes an American made CineMag USA transformer. CineMag has a rich history of manufacturing some of the most sought-after American-made transformers. CineMag products date all the way back to World War II (as Reichenbach Engineering) and were pivotal in creating some of the most legendary audio products in the last 100 years. This transformer helps provide the present top end and the LARGE bottom end one would hope to get from a 251-style condenser microphone.

Premium Tube & Capacitors

The WA-251 uses a premium 12AY7 vacuum tube that adds warmth and depth to the microphone’s signal. The WA-251 proudly uses polystyrene coupling capacitors, WIMA film capacitors throughout, and an imported Solen French capacitor on its output.

Hand-Tested, Elite Build Quality

Every single WA-251 is meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.

Great shoes that are well made, lite weight, and comfortable.
Size: 12, Color: Brown
Just received my 2nd pair of shoes from Bruno Marc in a size 12. These are really lite and comfortable. It can be dressed down to be a casual shoe or dressed up with a nice suit. These run true to size so I ordered my usual size 12 and the fit was perfect. Being my 2nd pair of Bruno Marc's, I like the quality of their shoes and each shoe is described appropriately on fit and comfort. Insole of these shoes were awesome and provided soft comfort on the feet along with a slight arch support too. Will definitely consider ordering more Bruno Marc shoes in the future.

Cushioned, comfortable, stylish and a rubber sole!
Size: 10, Color: Brown
These shoes check multiple boxes for me, comfortable, cushioned, rubber sole and stylish. As my feet grow old and worn out, I'm on a constant search for comfortable, cushioned shoes that are suitable for work and dressier occasions. I have tried many expensive shoes that look great but either lack cushioning, arch support and or comfort. One of the nice things is these shoes have a rubber sole, where most cushioned shoes have the foam soles which are great, but they tend to lack grip particularly when its damp/wet. They have average arch support, but the insole is removable and I put my own cushioned arch support. Love these!

OG Style
I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.

Size: 8, Color: Brown
Just buy it! I have put in roughly 15,000 steps in this shoes in 10 days and I can't believe how comfortable they are after this much rough use in short amount of time. I highly recommend this shoes to anyone looking for comfort in casual style.

WIDE Dress Shoes With SUPPORT
Size: 10.5, Color: Brown
I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.
