After a few years of 'managing' with my glass rack I have gone mad and spent a whole £30 on a second hand Atacama rack from eBay. It is an earlier design before that started with all the isolation elements and routed shelves. Seems pretty sturdy though, and heavy, and will fit better with the decor, as well as getting rid of all the resonant glass. The rack originally had spikes but were not included. Normally I would buy some spikes and have a listen with them in place and then not in place, letting my ears decide. However, it will be a PITA to set up the system have a listen and then take it a part to fit the spikes and do it all again, so I am taking the route of seeing what everyones thoughts and opinions are of the difference spiking the rack will make. I recon the best option would probably be AUVA, but it is a £30 rack  . I have a suspended floor, Pine boards on joists. I'm thinking perhaps best not to create a connection between the rack and the floor with spikes as, even with AUVA 100 under my Revelatory 851 there is vibration in the floor when Deep Purple is playing... amongst others! What do you think?  |

Put some Auva 50's on it, in my opinion it elevates everything you place on the rack and stops you worrying about using other forms of isolation.
I know it's 'only a £30 rack' but that's only becasue you got it for a good price. If it's solid enough already and (it looks so) fairly well made, it's worth isolating the entire thing. Again only my opinion, but I tested my racks (albeit a bit heavier) with combinations of Auva 50's/EQ's, neither, both, just EQ's, just 50's . . . . using a set of 50's on the entire rack was certainly the most cost effective way of isolating everything on the rack.
Go for it I say,
failing that I also had decent results just spiking the rack through the carpet to my screed floor underneath. You may get different results spiking them (coupling) to the wooden boards underneath. The 50's also take that variable out of the equation.
Good luck

Interested in what you say about, in your opinion, Auva 50s have as good, if not better impact, than EQs under each piece of equipment. I have been toying with trying EQs but finances have been a little stretched of late! |

I have been toying with trying EQs but finances have been a little stretched of late! Hi Pete, no problem. I must caveat that though by saying I only tested the EQ's for a couple of days before moving things around again, had I allowed them to 'settle' for longer, their effect may have been more profound, who knows . . . Either way I felt they all had a positive effect but the Auva's made the most sense financially. Also some of my equipment (BT2 etc) are quite a small footprint and some of the base has screws protruding out the bottom so I wasn't able to get the EQ's in the perfect positions on all the equipment. Just another small factor that may affect your decision. |

I would certainly say using the Auva 50,s is the right way to go . Remember you only need four so that is a nice saving . Only issue is there are not many 50,s about at the moment . Contact Jason and see what he says . If you can not get a set I currently have four I could send you but would need them back for when my Quads return in a couple of weeks . Let me know .

I am astounded how changing this to this rack has improved everything. It looks loads better and..... a really distinctive improvement in soundstage, detail and lower noise floor... all the usual suspects. I was aware that the rack would make some difference but was not prepared for this. It was £30!! Ok, it is well made, heavy and substantial, but nothing like some of the medium to higher end racks out there. I'm just running it with it sitting on the carpet, relying on its mass. How can additional isolation make it better? How much better will it get. We'll see.

Result Pete, well done, have had my next rack lined up for a while and it's a Atacama - racks do make a difference and there's more to be had by paying attention to each piece of kit and applying even a liitle isolation there. |

Are you putting a turntable on the rack?
If not I'd just leave the rack sat on the floor, vibration won't have any effect on the output of solid state components, not even at earthquake levels.
Don't get sucked into FOMO especially as you say you don't have much spare cash.
If you got to try something get some of the rubber washing machine feet for a fiver.
Spikes never improve anything.
If you are putting a turntable on there then ignore this, everything you do to a turntable and what it sits on changes the sound of it to some degree.

That is on a rack on the wall. The same Sound Organisation one I bought 40 years ago from Audio Excellence in Crwys Road Cardiff. It’s had a coat of paint and panza shelf since then though. |

Sensible option with a suspended floor. Leave the rack as it is then. Looks good and looks neat and tidy - Just accept that you'll already be getting the optimal performance from the stuff that's sat on it and don't give it any further thought. Don't waste money you don't have! |

Just sold my old glass rack. Purchaser was absolutely delighted with it. He was asking about how I used it, so I went into the detail as you would.
I asked him how he planned to use it. Ah, he said, for displaying my sculpture. He is a sculptor, spikes or not spikes was not really something he was bothered about. He took them all the same as he felt they may become part of his work.
I'm just glad that someone has a use for the rack, whatever it may be.
