AFI FLAT Record Flatener


I have had a FLAT (that does have a nice ring to it) for several months and here are my impressions:

1.     I love the look and what appears to be very solid German design and construction.

2.     Its operation is straight-forward and it has performed without any issues.  The only thing I would note is that, as stated in the user manual, the cool-down cycle will not function properly in very warm ambient temperature.  It basically cannot fully complete the cool-down cycle.  After confirming this for myself (I am guessing the room temperature was around 27 or 28 C) I from then on ran it with my aircon on (24 C ambient temperature) for the cool-down cycle with no issues.

3.     I have found its ability to flatten records excellent, five stars. This is described as the Standard function. I thought that I would have limited use for this feature, but since getting the FLAT I have been much more observant and found that quite a few new records that I have bought are dished.  The Standard cycle has successfully flattened all my warped records.

4.     It also has another function, Relax, which is of much interest. This is a milder version of the Standard cycle.  Unfortunately, there is zero description, apart from how to operate it, that I could find in the 19 page user manual on this.  I wanted to know what Relax is meant to accomplish and whether it can be used on both played and unplayed records, and new and old.  I have been told, but have not been able to substantiate, that the designer believes it to release something trapped in the vinyl during pressing. I wanted to know whether there is any audible difference using this cycle so I managed to find two identical unplayed records in my collection of Joni Mitchell’s “Blue”. They are US pressings but not the original 1971 pressing but must have been a subsequent Warner Bros/Reprise “Super Saver Series” reissue which I picked up around 1987-88.  I checked that they had identical Matrix/Runnout identifiers.  I cleaned both with my KLAudio Mk2 cleaner and used the Relax cycle on one.  A day later I played the non Relaxed record with a friend with excellent audio ears.  The recording quality was not the best.  We then put on the Relaxed record.  We were both amazed.  There was a very significant difference.  The non Relaxed record was irritating and the Relaxed record was transformed to listenable.

5.     I later listened to a 1987 German pressing on Warner Brothers of “Shaka Zulu” by Ladysmith Black Mambazo.  I would have had this record for over 25 years but had not played it.  I had washed it with a KLAudio Mk1 in Nov 2014.  It is an excellent recording and pressing. I put it through the FLAT’s Relax cycle and listened to it again.  It is not often that I can compare two events separated by 18 hours and categorically be sure of the outcome.  The recording had a significant increase in ambient information that turned an excellent recording into something special.  I think also that the soundstage was improved in width and solidity.

6.     The Relax cycle will only take out the mildest of warps.  Nearly all warps need the Standard cycle. 

Since, I started to Relax FLAT all my best recordings.  I highly recommend this device to take out warps, and also more importantly for me, to Relax favourite recordings for improved sonics.  I would not be without it.

All the best,

Very interesting. Thanks for posting your review- did you buy this? I hadn’t even heard of it-- apparently Roy Gregory reviewed it this year, and had the same comments about the "Relax" function- not a lot of information from the manufacturer, but according to Roy that feature "heats any disc to a lower maximum temperature and then slowly cools it to remove mechanical stresses from the pressing."
Flattening is, to me, a dark art. I have a Vinyl Flat and a Furutech DF-02. Both work pretty effectively, the difference largely being the degree of labor involved. I have yet to establish guidelines for "repeatability" of effectiveness, and I doubt same exists, largely because the problems of warpage and potential damage each record suffers from vary widely, record to record. (i.e. a warped record that is barely playable may get flattened but still be unplayable due to other problems and occasionally, flattening exacerbates the problem).
One thing I have done on the Furutech is to reduce the amount of heating time applied to medium weight and light weight LPs- which are often the records most plagued by strange warps- due not only to thinness of the pressing, but probably owing to the vinyl formulations used at the time. (I’d say my success rate is probably in the range of 70-75%, which is pretty good, given that I’m usually flattening old records with troublesome warps).
Whether I’d go through the trouble of "processing" otherwise unwarped records to improve the sound would remain a question mark to me, but I haven’t heard it. I’m a little wary of applying heat to records, and only jumped into the "flattening" arena to salvage otherwise unplayable records, so consider the risk small on that front.
Would be interested in further info if you get more from the manufacturer and/or have more to report based on your use of this. It certainly is a nice looking piece of design.

postscript: curious to know if flattening function is lower heat, longer cycle times than the Furutech? The price, Harold, according to Roy’s piece, was in the neighborhood of 2000 Euros (2400-2500 in Germany), though another site quoted a higher price--perhaps that depends on territory/location of purchase.

@whart , A friend helped me to get a unit on loan as I had some warped records. All I initially intended to do was try and take those warps out, and then return the unit. I had it for 2 months. I have since placed an order and will get mine in Jan 2017.

I used the AFI on thin to 180g vinyl and it consistently took all warps out. This was on the Standard cycle. It takes the record very steadily up to 60 degrees C and then from memory keeps it there for 5 or 10 minutes (I think the latter), and then very slowly brings the heat down. This cycle would typically take around 4 hours. The Relax cycle, as far as I could observe, was the same except that it only kept the record at 60 degrees C for 1 minute. There is also a user programmable cycle which I did not try.

In the time I had it, I Standard cycled or Relax cycled more than 40 records with no issues.

The design is lovely and the FLAT is beautifully made. This is a set and forget item during its operation. It is undoubtedly expensive. I could not have justified the purchase for simply flattening, although I may be changing my mind on this, as now I am more focused on looking for warps and I seem to see more of them in my collection. And as I mentioned in the review, I cannot believe how many of my newly acquired recently pressed records are dished. However, the sonic results from the Relax function have amazed me and moved me to make the purchase.

After I get my unit, I will report back on my continued usage experience.

All the best.

Very interested in disc flatners Further info on use/results, cost, where to obtain, build quality would be highly appreciated.

Have great interest in TTs that use vacuum hold down. But as far as I know only SOTA TTs and Tech Das can be had. I certainly believe Flat disks are beneficial to SQ. Most TTs have a clamp. Others have clamp & ring. I always thought the ring would be PITA.
So flattening and "Relaxing" your Vinyl is of great interest to me; especially "Relaxing" Since I am a vinyl guy. Taking care of my vinyl started 45yrs ago & being "picky" about the my record purchases from the beginning 
I have a VPI for ever, bought an AD in January, Own Fureteck D'mage & D'stat since they came on market. Stylus care too.
It all starts with the source! Taking care of it pays off as you move up your Front End. TT, Arm, Cartridge. I have 3000 records. Only 3-4 unplayable but hopefully I could flatten them one day. Others are dished or have long warps that are playable but always thought they would play and sound better if they were flat.
The "Relaxing" part is the most interesting. From an Engineering view point, this makes sense.

Again! It all starts at the Source! 
Giving the TT, Arm, Cartridge LESS Work means they they can retrieve the most from the groove,

Any more Info, thoughts, experience that you share would be greatly appreciated. Should benefit others too.

Thanks
Thanks, @bluewolf .
Like many things in life, once you focus on something, like warps, you see them everywhere! :) Those heavy ’50s and ’60s records are pretty bulletproof; the problem really seems to arise with the stuff in the later ’60s-after the "pop/rock" boom, where lots of records sold in big quantities, probably calling for cost efficiencies in manufacture--and of course oil crisis and later stuff. Funky storage- heat, probably contribute to it as well. New records- the few I buy of ’standard issue’ (not fancy audiophile stuff) come warped sometimes, but those seem to flatten very easily-- maybe vinyl memory--how long a record has been warped--is a factor. (Alas, my Cloud Atlas Sextet record, a new "cheap" record that is now out of print and no longer cheap--repeated cycles improved one side, but it still skips on the other). Are you in the States? (Just curious if the product is available here). regards,
may you always have flat, clean records,
