Heritage Audio OST-4 V2 5-stars Reviews

Awesome lunchbox!

Very quiet and stable! I'm buying another one! Recommended!

Sturdy and with enough power

Very solid and provides more than enough juice to feed a couple of preamps with transformers and a stereo compressor with transformers and valves.

I'm very happy with it.

Ideal size for Vocal Signal Chain

Having my first 500 Series is a good experience.

The unit is a neat and tidy size, solid unit, secure slot fit for each unit also.

Great to have rear buttons to send signal rather than rely on patch leads - although still totally easy to patch out to DAC at any slot.

Have not detected any unexpected noise as yet in the signal, so happy with the purchase. Recommend for 4 module signal chains.
