PS106-DC as reviewed on top; Purist 108 version below which, by eliminating the central filter block, can accommodate eight outlets instead.  

Would you have that again?

When my wife and I eat out and order unfamiliar dishes, that's what we ask each other afterwards. It's far more relevant than whether we liked it.

After my review of the British Puritan Audio Labs PSM156 flagship active line conditioner, my answer was an unequivocal yes. But what if your budget were only half its £1'450 ask? Sometimes eating out wants kebab or burrito. Rice with refried beans can be most satisfying when rolled up with some guacamole, cheese and hot sauce in a grill-striped tortilla. No need to get all poncey. Starched linens don't fill empty stomachs.

To find out what today's £675 power strip with less intense filtering leaves under the table versus the range topper, I asked Mike Lester for a loaner whilst his big boy was still in residence.

"All of its output sockets now have the same 15A path to them, with 15 amperes being the overall limit for all outputs combined as its big brother. The supplied power strip also has the new non-sacrificial gas voltage spike clamps. The current up-rating is not yet reflected on the top print as we are awaiting fresh front-plate metal work."

Lifted straight off its web page, today's entrant packs multiple cumulative sympathetically-tuned stages of purification with 19 independent elements; 6 x 15A outlets each with independent re-filter stages to eliminate cross contamination between connected equipment; direct maximum power routing to all outputs to realize full dynamic performance; cleansed earth to remove noise from the earth; star earthing to eliminate ground loop hum, reduce the noise floor and improve definition; massive 30'000A of three-dimensional surge protection; internal silver-plated OFC copper wiring with PTFE insulation; C14 type IEC; electrically and magnetically shielded casing of 43 x 23 x 11cm WxDxH and 2.7kg; available with all common output sockets (UK, Schuko, France, Belgium, Switzerland, USA  etc).

The companion power cord must be terminated with a 20A plug to fit. Obviously Puritan's own which comes with it is.

After my same-brand comparison, I could then set up a proper strip joint with our 6-outlet Furutech RTP-6 [€800 at its time] and e-tp80 [€650] passive power strips. Zen purists, greet British puritan. Who would have the last laugh? If the PS106-DC were only as good as the passives and no better for adding active AC/DC filtering, just one lightning strike as we once had in Cyprus would settle that score. As building contractor, our landlord had overspec'd our mains circuit breaker. That clamped down fast enough to protect all of our electronics. Three telephones and two answering machines weren't as lucky, however. The deafening strike which left my ears ringing for hours had melted them over the phone line. At our small local computer repair shoppe the next day to buy replacements, the guy behind the counter grinned. He knew exactly what had happened. Regular lightning over Coral Bay was good for business.

Active version on top, passive 'purist' version below.

To properly understand PAL's no-nonsense approach on the power delivery subject, read my first review. That dispenses with more formalities to let us go straight for sonics.
