A scratched that was itched? Yes, Jim. It probably isnt far away enough to make any real difference in all honesty. Annoyed my cable broke though. Typical with people visiting over the next few days!

Just slap them back together for tomorrows listening Oli if that's possible.? It is, but it's the cable from the SSD to the Pi that's broken, and that's the issue.

Been thinking of converting my 686 amplifier into a dual mono. Trouble is, the case is a bit tight to really get any transformers in there so i thought maybe put the PSU in a separate box. I have a box that was earmarked for a different project but it is suitable.
Any opinions on that?
Interference? Voltage drop?

I think a separate box would minimise interference. Unless you go a fair distance away, Voltage drop should be minimal.

As a temp fix, could you play to the pi using upnp? Think I remember you saying you used jriver and I’m not sure if that will detect and play to upnp. If not, you could use a trial of Audirvana (which I use to play to my 3 pi’s), let that scan the files on your SSD, making sure the upnp box is checked in the pi set up menu.

Anyway, how is the new cartridge working out for you?

Anyway, how is the new cartridge working out for you? Ye, it's pretty impressive to be honest. I did so a fairly long winded post in the Review section, describing the first 20 hours. Dont feel like I've downgraded, which is always a bonus.

I have a JRIVER set up, which will stream to the Pi, but I found that everything sounded far better when the SSD was connected directly to the Pi, which is not possible at the minute.

Ah, ok. Not a solution then. Audirvana does sound pretty good, but I don’t know if it would be as good as a direct connection

After yesterdays utter disappointment of getting the PecanPi to sound at it's best, even with the help of jimbo's Sata to USB cable, i have spent this morning listening to the Pecanpi with Jim's cable and with the GPIO cable allowing some distance between between the DAC and the RPI. I was told a while back by TC of Coherent that if i could do this, i would be rewarded. I have to tip my hat, he was right again. I have noticed a real uplift in information from the recording. A reduction in bloat in the LF, improvement in transparency and a modicum of better individual space in the soundstaging. I'm hesitant to say a smearing of the sound has been removed but something has certainly happened. Dynamics have become a bit more punchy and quick. Better decay and attack. To be honest, i spoke with a few people about DAC's for Pi's recently and one guy who heard this felt it was a bit slow, which i had attributed to the BB chip. Today i am heaing a totally transformed DAC, which is a bit of surprise. It sounds faster and cleaner. I am totally loving it lol. So, there is another little addition coming for this rig, which i ordered about two months ago, so it may get here off the slow boat sometime soon. I'll say more about that when it eventually gets here. So, top tips for RPI Audio: 1) Use a SSD directly into the RPI with this cable: tinyurl.com/sokrzva2) Get a 40 pin GPIO cable and separate the DAC hat from the RPI, further the better i suspect. 3) Secure them both to a heavy platform with vibration absorbing feet More to follow

Now im totally neurotic about shards of metal getting into any F@cking cartridge i own, ***fuming*** I have just ordered a set of these Aluminium badboys. www.amazon.co.uk/Nagaoka-BN-7S-Cartridge-Mounting-Screws-Silver/dp/B0062KROLA/ref=sr_1_1?keywords=Nagaoka+BN-7S&qid=1582496737&sr=8-1EUR1900 cartridge now on the way, i need to protect it. Obviously, i wont need them all so if anyone want's a pair of them and wants to chuck a couple of quid at me, i'll send some....once i know which ones i need. Oliver, I've just been reading your blog re the metal shards found in your Kb by Killian. This is clearly an issue with the KB as on both occasions Killian checked the Vienna 'improved' cart, there were metal pieces present- some of which were causing measurable distortion. Other KB users should probably be made aware of this- a check might be worthwhile! Thanks for pointing those out. Just ordered. It might be a highly unusual occurrence.. but it has happened.

Yup, certainly seems feasible. Better safe than sorry for me these days, even if it's over cautious. I dont want the same thing to happen again, no matter how unlikely.

this does rather beg the question,where is the metal coming from?
i dug my inspection report email from killian,guess what? metal!
Good afternoon Jamie,
it has in fact arrived this morning and I have completed my inspection of it.
The tip does indeed need to be replaced, the suspension is in working order (no direct need for replacement), there are quite a few metal-particles that are magnetically 'sucked' into the front poleplate opening and they all need to be manually removed as they can interfere with the bobine (coil assembly). The alignment of the generator is slightly off so that needs to be re-aligned.
All in all a nice condition Kb which can be restored/cleaned/readjusted. Costs will be 312,- euro ex VAT (290,- for retip, 22,- for cleaning and the readjust is free of charge).

Wow, have we accidentally uncovered a potential minefield ?

Metal filings are in the pressings themselves I was told and it was a common thing on Supex's and their cartridges for Linn I remember. All the worn out ones we traded in again's replacements were like this and I'm surprised none of you seem to have noticed this before. Maybe higher riding cartridges are less susceptible to it?

Seems there may be an element of truth to Dave's "metal madness" Seems that for a period in the 70's, they regrinded Vinyl to be repressed into new LPs, thus creating the "Virgin Vinyl" movement. Enthusiasts that sought out non grinded LPs. However, the theory was that metal from the grinding process ended up in the raw material that the LPs were made from. Personally, I wont worry too much. No amount of brushing or cleaning will help as its embedded in your Vinyl.

A regular thing with low slung Asaks, karma's and Troika's with a good few hundred hours on them. Something to so with very fine metallic 'dust' in the vinyl presses getting into the grooves and MC cartridges having very powerful magnets. The green sheet of stylus cleaner may have got the worst grunge off the diamond, but obviously never went near the protective tape which covers said magnets.

No, I didnt think toud made it up, I know you are too serious about HiFi to do things like that! I just never heard of anything like it lol A bit of research does throw a bit of light as to why it's a very real possibility. Looks like I'll be sticking to remastered vinyl lol
