Get to know them!

Warm Audio's WA-2A set its target high: the most iconic tube compressor in history. How does Warm do it? Through economies of scale, mostly. They don't cut corners on components (the WA-2A employs a custom optical photocell and genuine US-made Cinemag transformers), but they do order parts and build in quantity, which helps to keep costs down. Like the original classic unit, the WA-2A gives you a completely discrete signal path and the same arrangement of controls. And yes, it replicates the original's coveted warm sound and forgiving nature. Elevate your studio to the next level with the Warm Audio WA-2A.

What can the WA-2A do for you?

Every studio needs a good compressor, and the Warm Audio WA-2A is designed after the mother of all compressors — the legendary LA-2A Leveling Amplifier. With its euphonic, fluid, forgiving sonics and all-discrete, all-tube signal path, the WA-2A is your go-to device for everything from caressingly warm dynamics control to full-tilt squashfest. It's fabulous on bass, kick drum, vocals — you name it. It's lovely for punchy parallel processing on drums, and if you have two of them, the possibilities become even greater.

Top-tier performance — and a stunning value

At Sweetwater, we're all about performance and value, and that's what the WA-2A gives you. At this amazing price, you can double your value and get two. With a pair of these in your rack, you can make that stereo piano sit proudly in the track, punch up your toms, strap them across your stereo bus for some mastering magic, and fortify your mix with serious warmth and glue.

  • Faithful re-creation of the iconic LA-2A Leveling Amplifier in a 2RU chassis
  • Completely discrete, all-tube signal path:
  • Historically accurate 4-tube circuit

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
