Summit Audio TD100 & TLA50

soundonsound.com

The Summit Audio TLA-50 shines as a robust, easy-to-use compressor that marries hybrid circuitry with classic valve warmth, making it ideal for individual instruments like bass guitars and vocals. While it excels in adding tube character and dynamic control, its slower response may struggle with percussive instruments and complex mixes. Despite its higher price point, the TLA-50's build quality and flexibility in interfacing make it a worthy investment for those seeking professional-grade sound enhancement.

there's a lot of talk about what sort of compressor this is, well, I have one and i opened it and looked it over.... this is a vari-mu but instead of using a a triode/duplex-diode tube for gain detection and control surrounded by triodes like vintage units this guy uses a common guitar dual triode for input gain and gain control with a pair of solid state diodes back to back for detection... this is like the SPL iron that uses different cheap SS diode arrangements for detection with triodes but without the transformers.... this compressor sounds excellent on ANYTHING and even with minimal gain reduction it adds weight to mono sources.... it is an absolute vocal champ sitting between an opto LA2A sound and like a gates sta-level but cleaner if you want. Absolutely bad-assed compressor/leveler. Built to WWII military spec, super sturdy. Neve style meter needs periodic recalibration via a trimmer. I intend to purchase at least 1 more and a TLA100 for bus work. Can't go wrong.
