Hey guys, I’m interested in buying the new clone of the EAR 825 eq. I have been talking with the builder, but I would like your help understanding some things about it.
In both units the mains transformer is very close to the output transformer. The original EAR, however, uses a toroid encased in metal (see pics). The clone uses an IE transformer with no case.
The builder says that they were able to: “achieved impressive results exceeding: Signal to Noise Ratio, reference to +4 dBu, 8Hz-40kHz: 95dB. It's amazing result BTW.”
I recently watched a video where EveAnna Manley details Manley’s upgraded switching power supplies and that it drastically improved their noise and hum performance. The Manley site quotes the Massive Passive’s signal to noise performance as -92db. This figure is worse than the EAR clone, despite Manley’s “This is Massive audio excellence which starts with this superior power supply. All lines are super-quiet in this low radiating high frequency design”
The EAR clone builder states that only input transformer placement matters, and that output transformers are immune to EMF. This is new to me. I really want to buy this thing, but I don’t want to get it and hear a ton of hum in the output, and have to send it back. What do you guys think? Should I start placing my output transformers right next to the Mains transformers in my new builds? You can browse the original thread on Gearslutz in the “New Product Alert” category if interested.
