Excellent and boxed.


His new P6100M monoblock power amplifier is an attractively styled thing, but we're not quite in Devialet territory – yet that's not the point. Once again, it's what's under the hood that counts, and here we have a 100W RMS amplifier that's heavily biased into Class A. It uses reliable and rugged MOSFET output devices, and when sold as a pair costs just £3,500. That's the sort of money that serious audiophiles routinely stretch to, providing the product gives the desired result. “Each amplifier runs 400mA of bias current, and so is good for about 10-15W of Class A before moving into B”, Nick tells me – so in most people's listening typical listening conditions, they'll rarely get out of Class A.

He's a serious tube amp fan, but real-world enough to know that this technology isn't a universal panacea. “When I originally started the design work, I wanted to make something that sounded like a good 2A3 direct heated triode valve amp in the midrange and treble, but with solid-state power in the bass”, he told me. That's why he chose a particular type of MOSFET output device, to get a claimed 100W RMS per channel into 8 ohms, and 190W into 4. Instead of using multiple arrays of output devices paralleled up to achieve its rated power output, this amplifier sports true single-die, high power MOSFETs, run in complementary pairs to give a balanced output stage. Before this, a special driver stage feeds each of the two MOSFET output devices in each amplifier.


The 100M part of its this amplifier's name refers to its output power and the fact that it's a monoblock; however, the naming system actually appeared with “the parent that produced this offspring”, a 200W monoblock which was downsized to create this but never productionised. The P6 part of the name refers to the fact that it's a small push-pull amplifier; Nick says it's, “push (driven by push, pull), pull (driven by push, pull) – so that's six Ps…”


The thick aluminium fascia panel sports a sturdy backlit metal power switch. Round the back, you'll find chunky binding posts for one set of speakers, an IEC mains inlet plus RCA and XLR inputs; a small switch lets you toggle between the two. Inside there's a large capacity power supply with help from, “as big a UK-wound transformer as we can fit in the case”, Nick tells me. Non-ferrous casework is used, and extra care has been taken to manage thermal memory effects, he says. This amp comes in a choice of silver or black finishes, and the overall standard of build is very good for a small manufacturer. Vital statistics are 430x110x260mm and 8.5kg per amp.
