Hi
@displayname,
I've had my Okki Nokki (I think mine's just called the version 2) since February 2019 and had a similar consideration set as you. I went with the Okki Nokki for the following reasons:
- Small Footprint. Between the VPI, Pro-ject, and Okki Nokki, the Okki Nokki was the smallest. I knew that if mine wasn't easy to use, I wouldn't use it since I know how lazy I am. It was also the nicest looking out of the three and I didn't want to tuck it away somewhere, since again, knowing me, I wouldn't use it if it wasn't as easy as possible for me. However, I think I might build a stand for mine at some point.
- At the time, the Okki Nokki was the only one (out of the three) that wasn't made out of MDF. I've had aquarium stands made out of MDF and no matter how careful I was, I'd always get water spills so I think that's just ingrained in my head that MDF around liquids is not good. It probably isn't a huge concern for an RCM, but I have seen pics of leaking VPIs and the MDF getting damaged, so I wanted something made out of something other than MDF. Using it now, it seems like there's not a huge chance of large enough amounts of liquid spilling, but I've also read of RCM reservoirs leaking....
- Sound. I found a YouTube video somewhere comparing the sound levels. From what I remember, the VPI was pretty loud (I remember reading somewhere the guy wouldn't clean like an hour before listening sessions 'cause he felt like it affected his hearing). The Okki Nokki isn't quiet, but I also don't feel like I'm going to lose my hearing after using it. I'd say it's about the same loudness as my Miele vacuum cleaner and definitely not as loud as a shop vac. I can take dB measurements if you'd like.
- Vacuum tube. I read a lot about vacuum tubes breaking or ease/cost of replacing tubes (I think the VPI requires the whole tube to be replaced?). It's $10 on Amazon to replace the vacuum tube strips for the Okki Nokki.
I also happened to find it at a good price at Turntable Lab...they had 'em for $450 (and it included the $50 lid for free and free shipping, plus I got another small discount for some promo they were running at the time). I approached it as a tool that'll eventually wear out so thought I'd give it a shot and I'm really happy with it.
My only gripe with it so far is that the acrylic lid has seams that are coming apart. It should be easy enough to fix with some acrylic glue, but still a little annoying since it seems like it was just a sloppy job from the factory. Oh, also, I don't use the included brush (bought a MoFi brush and only use the included brush for the occasional rinsing step). I use the TTVJ gold for the washing fluid.
As a disclaimer, I don't have as large a collection as most of the people on this forum, so I'd say I'm a pretty light user (I only have maybe 100 records, and I only buy new). It was also one of the first accessories I bought for my analog setup. Not sure how this thing would hold up to much heavier use, but I don't have any concerns. I'll also admit I was a little on the fence about buying from a company I hadn't heard of (especially compared to VPI & Pro-ject) but I'm still really happy with it.
Hope this helps, and good luck!
