I’ve been an audio enthusiast for over 40 years and the Hattor Big is the best preamp I have ever owned. The build quality is excellent and that includes the very functional and convenient remote. My unit has the AMRG resistors and New Class D opamp. I would recommend ordering your unit with those best quality parts for maximum performance. The Big does everything right….excellent detail retrieval, huge soundstage, great tonality. I leave it on 24/7 and simply make sure the volume is at 0 and the LED lights are completely off after a listening session. The Big replaces a well known boutique 2 chassis tube preamp made in Australia.
At some point, I may order an amp from Arek.
I have paid close attention to A/C filtering in my home, power cords and cables to allow the Big to get the very best performance.
I highly recommend this product!!

I have been using my Big Active / Passive preamp for Almost 2 years and I can say that it is the best Hi-Fi piece that I have every owned in 45 years. Very neutral and accurate without any electronic signature even in active mode with the class D Opamp. Beyond highly recommended, a fabulous product and a very sleek remote control.

Wow! It was a great experience here with Hattor Preamp. Arek has given me some nice advice on the right options. Mine is with OPAMP Active Stage, 64 steps SHUNT- AMRG + VISHAY and dual Mono.
The build quality is superb. And most importantly the sound is fantastic. Much improved sound Stage and separation in comparison with my old preamp.
And the remote control is so useful. Straightforward and it just works.
Thanks Arek and your preamplifier has gotten me to enjoy my music again.
