Pico Binding Post Grounding Blocks (BPGBs!)

Okay, we confess the name is a little confusing, but naming all the different versions of the Pico grounding blocks has proven to be quite tricky.

This version of the Pico grounding block is built specifically for providing RFI and vibration grounding for the amp output and speaker input part of your system. It is, internally, identical to the Pico component grounding block, having the same two independent inputs with internal RFI absorption and acoustic labyrinths.

But externally it is fitted with a pair of universal binding posts rather than RCA connectors, and the leads have a banana connector at one end and a spade at the other. This is an ideal arrangement for use on amp outputs and speakers because it means you can use the supplied leads either way around on the amp or speaker binding posts to complement the type of connectors on your speaker leads. If for example on your amp connections you have spades on your speaker leads then use the banana end of the pico leads into the centre of the amp binding posts and the spade end onto the Pico itself. And of course they are supplied as a pair so you have one for each channel!

And they function in exactly the same way as the other Picos – draining out unwanted vibration and RFI from your amp and speaker terminals.

But looking at the bigger picture, they provide another option in the Vertex range, for dealing with systematic faults in the amp and speaker area of your system. We already have the full Moncayo speaker leads, the inline Moncayo extension blocks and the mini-moncayo speaker links. The Pico BPGBs are not in-line of course, so do not offer the full ‘protection’ that the Moncayos do with their in-line blocks. But the Pico PBGBs can be used with other high end brand cables that you may have already invested in, to add RFI vibration reduction at a relatively low cost.

But Also in a full Vertex context they can add even more performance. During their development we did extensive listening tests at The Right Note, in Bath, England. We had various very high-end main components in the system, fully rigged with HiRez Vertex power and cables, and all on a full LeadingEdge rack system.

The sound was incredibly good, but when we added the BPGBs to the output binding posts of the amplifiers it got better again. In particular was clearly a further improvement in phase accuracy, timing and scale. The image and sense of space, whilst already exceptional, improved dramatically. Images on some Roger Waters tracks, that were already around at the 9 o’clock and 3 o’clock position, moved even further back. On The Ballad of Bill Hubbard, the old man’s voice was now coming from behind my left shoulder! The cicadas were all around me and the soaring guitar notes were strong and central but originated from a great distance. The whole experience was as if one was in a huge space but also with certain elements very close – almost talking into your ear.

On some acoustic guitar tracks the sense of changing tempo and sheer speed of some of the playing improved considerably. Delicate passages drew you in for their subtle, intricate detail, then amazed as they built into the strong yet accurate playing at the crescendos.

Whether you have other Vertex products, or want to sample what the Vertex technology can do for the musical performance of your system, we strongly recommend you consider trying a set of the BPGB Picos. We think you will like them – a lot.
