The Ferrum ERCO Gen 2 is a landmark evolution of Ferrum's entry-level DAC/Preamp — now rebuilt from the ground up with a completely new firmware architecture and crucial analogue circuitry upgrades. The result brings ERCO one giant step closer to WANDLA, Ferrum's flagship converter, at an unprecedented price point. If you want flagship-level performance without the flagship price tag, ERCO Gen 2 is the answer.

A Complete Reimagining, Not Just an Update

ERCO Gen 2 goes far beyond a standard firmware update. Ferrum's engineers ported the full SERCE software stack — the same platform powering the flagship WANDLA — directly to ERCO. This means ERCO Gen 2 behaves exactly as if it were built on SERCE, bringing 768 kHz support, DSD512 playback, improved DAC performance, and WANDLA's most-loved HQ Apodizing digital filter to an entry-level product. An extraordinary achievement at this price.

Analogue Improvements

After designing WANDLA's advanced current-to-voltage (I/V) converter, Ferrum's engineers applied everything they learned to ERCO Gen 2. The updated I/V stage delivers a more detailed, natural, and engaging sound signature — a fundamental improvement that goes well beyond what software alone can achieve.

Digital Improvements

With the full SERCE software stack now running on ERCO Gen 2, the digital improvements are substantial. The HQ Apodizing filter — WANDLA users' most preferred filter — is now included. ESS filters are bypassed for non-MQA signals, intermodulation and intersample distortions are reduced, and output levels are adjusted to meet Red Book standard on the line output and maximum output power on headphone outputs. USB playback of 768 kHz signals is fully implemented.

Key Features

SERCE-based firmware
The full SERCE software architecture from WANDLA runs natively on ERCO Gen 2, delivering a level of digital performance previously unheard of at this price point.

Updated I/V converter
Analogue stage improvements informed by WANDLA development give ERCO Gen 2 a more detailed, natural, and engaging sound signature.

768 kHz & DSD512 support
Full high-resolution playback up to PCM 768 kHz / 32 bit and DSD512 via USB.

MQA Decoder & Renderer
Full MQA decoding and rendering on USB, Optical, and Coaxial inputs.

HQ Apodizing digital filter
The same filter preferred by WANDLA users, now available in ERCO Gen 2.

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26

My pit bull loves them.
Color: Purple
I picked up the Frienhund Tough Dog Toys 3-pack for my large, heavy chewer, and overall I’m pretty impressed. Right out of the box, the toys feel solid and well-made—definitely more durable than your average chew toy. My dog usually destroys new toys within a day or two, but these have held up significantly longer, which is a big win. They also do a great job of keeping him occupied. The shapes and textures seem to keep his interest, and I’ve noticed less destructive chewing on furniture since introducing these. That alone makes them worth it. The only reason I’m giving 4 instead of 5 stars is that while they’re very tough, they’re not completely “indestructible” (despite the claim). After a couple of weeks of heavy use, there are some visible wear marks. Still, compared to most other toys we’ve tried, these last much longer. Overall, a great option for medium to large dogs that are aggressive chewers—durable, engaging, and a solid value for a 3-pack.

Great Toys for Chewers
Color: Purple
Love these dog toys, they are so well-made and keep my Golden Retriever busy for hours. The variety of sizes is nice too, they aren’t heavy at all, but they sure hold their shapes , even with the constant chewing. The price was very reasonable, too.
