van den hul Grail SX

van den hul, phono stages, analog

The van den Hul Grail SX is the successor to the Grail SE and is the company's new flagship phono amplifier.

A new model, a new circuit board
In developing our flagship phono preamplifier, we have also redesigned the circuit board. With the new circuit board, the overall sound quality has significantly improved. The Grail SX delivers notable enhancements, particularly regarding soundstage and airiness.

Mixed operation for input and output
The new Grail SX allows for mixed-mode operation of the inputs and outputs. When receiving a symmetrical (XLR) input signal, the output can be used simultaneously in symmetrical (XLR) and asymmetrical (RCA) modes. The same applies to the asymmetrical (RCA) input, where both outputs can now be used independently and simultaneously.

Automatic load impedance
Similar to its predecessor, the Grail SX features automatic load impedance adjustment for cartridges, ranging from 10 Ohms to 400 Ohms.

Designed and made in Europe
Like all other van den Hul products, the Grail SX is designed and manufactured in Europe.
