This might be the single biggest recommendation I have ever given on this channel.
Meet the De Cillia Single 25โan amplifier that looks polite and safe on the outside, but hides an absolute monster within. Get more info here - elkqr.link/DeCilliaSingle25
I actually tried to review this amp previously, but I forgot I was filming, called the builder, and bought it on the spot. It features a KT-150 tube (usually found in high-end Hi-Fi systems, not guitar amps) which allows it to go from pristine cleans to massive grit without ever falling apart.
Hand-delivered by the builder Arnaud from Vienna, this amp is expensive, rare, and completely "almost perfect". Let's break down why this was my "No Price Limit" Amp of the Year.
Recorded with a Lewitt 440DM and a Lewitt LCT540
