2nd generation EIGENTAKT PURIFI 1ET6525SA (successor to the 1ET400A)

[Oniiz86]

Can anyone tell me whether the 1ET6525SA design has already been implemented here?: Link
The 510 W @2 Ohm would speak for it.
The bridge-mode has more output power @4 ohms than a 1ET9040BA!
The same has already been seen with an MXA-8400 and M23/M33.

@pogo I believe it's based on the 1ET400A as its advertised with a bandwidth of 60kHz, you can bet if it were the 2nd Gen 1ET6525SA they would most certainly be touting the increase in bandwidth of 80kHz

If -1dB was assumed as the reference, this speaks more in favor of the 2nd generation, as does the power specification for 2 ohms.

You may be right that it is already iET6525SA, but be aware (you must know that already though) that Purifi does not give "continuous" rating as it depends on the thermal system. It also does not specific what "short term" means, the 510 W @ 2 ohm load is qualified in 1) Short term, and 2) Power is limited by overcurrent protection system. Not really too meaningless if used to compared with other amps in terms of apples to apples.

When I buy a Purifi amp the dependability, timely order fulfillment and willingness of the builder to go the extra mile is what decides who my next order goes to - NOT a difference of 2-3 dB in SINAD even if real. Frankly, small SINAD differences are TOTALLY unimportant in the listening room. Having purchased amps from both Boxem and March Audio, I would definitely go back to Boxem. Enough said...

Both are good and accomplished vendors but what turned you off March?

 

[David_M]

When I had a problem with my March Purifi amp it was within the warranty period he was currently advertising but evidently he didn't want to honor that same period for those who purchased from him when he started selling Purifi. He needed the amp shipped back at my cost to Australia from USA and back at my cost, plus he was slow to answer emails and delays occurred during the initial order. In my opinion, March isn't the best fit for US orders and to say support was less than I hoped would be kind. I found I can do much better as a US consumer avoiding March. My experience with Boxem was far superior. He actually seems to care about his customers.

I wonder why your amp failed. He informed me that he has very low return rates and that's why he can offer 5-year warranties with confidence vs standard 2 years others offer.

 

[David_M]

My experience was March doesn't go out of his way to help US customers when a repair is required. Luckily, Purifi amps can usually be repaired by replacing a module. I was able to find a US amp builder that could repair it for me at a reasonable rate. I learned paying a premium price for an amp from March, doesn't provide premium service or a premium product. We have many good options for Purifi amps today. Not much reason to buy one from the other side of the world, where support is limited.

Interesting take ... thanks for the info.

Hey ... I found this thread where it states your amp had a 3-year warranty (and not 5 years) and was out of warranty when repairs were needed. Since it was out of warranty, return shipping costs, at the least, are borne by the customer, which makes sense. I believe this is standard practice for all sellers.

3-year warranty

Australian Consumer Law (ACL) does apply to Australian sellers though even when they are selling to overseas customers.

Weird that March Audio cannot reply directly here himself and instead has to ask users on his own forum to do it for him.

 

[David_M]

I believe he would respond if he was permitted to do so.

I believe he would respond if he was permitted to do so.

That's my point. There is a reason he isn't allowed to (even after making multiple fake accounts over the years). How someone conducts themselves in everyday goings/interactions says a lot.

Which goes hand in hand with Amper's suggestion of other options to purchase from. And no, I'm not advertising myself. I've already made clear that if our product is not in someone's running for purchase, there is a clear winner I'd recommend well and above March for various reasons. One being is he hasn't been kicked off these forums for his actions...

My 2 cents, of course.

Boxem amps are also not built/assembled in USA, isn’t it right?

Hello - I'm considering these modules (audiophonics power amp implementation ) with a miniDSP Dirac for room correction. Is it a better option than something like a Lyngdorf TDA1120 ...assuming power is not a concern ? The amp will be driving either Graham Audio LS6 or KEF LS50 Meta. Thanks

From my experience it is hard to go wrong with Audiophonics. Currently have the
Audiophonics HPA-S500ET with Minidsp SHD. Where I find that Audiophonics stands out the most is in their after sales service. In my over forty years of being in this hobby. I have never dealt with a company that has been so quick to receive,replace and resolve a product issue.

How is the sound with the minidsp? Im having some issues using one w/ Dirac, with a Sugden ...am thinking of the AUDIOPHONICS LPA-S450ET.

The TDAI 1120 has been around now for approx 5 years. So I would assume that there will be a new release this or next year. Hence, I would personally not buy it right now - even tough their room correction feature got some decent reviews.

The Minidsp SHD is very competent in my system. No issues in the signal path.

Can y'all help out a reformed audiophile? I'd like to try a 1ET6525SA implementation and have narrowed the choices down to the Boxem A series, mainly because I love the casework. But before I pull the trigger, I was wondering if there are any practical reasons to go with dual-mono over stereo. I know the audiophile justification is better channel separation, better imaging, etc., but there are no measurements to back this up in the case of these purifi modules as far as I can find. The price difference is minor, but I would still prefer not to spend more for a vestigial power supply. Am I missing anything regarding stereo vs. dual-mono? Thanks in advance.

I own the Boxem A 4216/E2 with WBT binding posts and the high gain input voltage customized to the low-ish output from the Denon x3800h pre-outs (1.4v).

I have experience mixing music and it sounds 100% identical compared to my dual-mono 200W / 8 ohm class A/B amp. For context, my speakers are 95db / 4 Ohm sensitive with a large AMT that lays bare fine details. According to the power meters on the A/B amp, I never even break 1W which makes perfect sense given that my measured peaks typically top out at 89db.

The Boxem runs cool, is very, very well built and unlike my 63lb dual mono amp doesn't cause my lights to dim when I turn it on. I wouldn't hestitate to take it into my local dealer and challenge him to a double-blind listening test with his $100K YGs and the allegedly needed D'Agostino amps to drive them but have no doubt he would not agree to that.

Having dual monos is a step back in usability, because if you have two amps that you need to switch on, one at a time and a walk in between. But that very same step can be a reason to get dual monos if you like that sort of a "ritual" before you start listening and are not concerned about usability.

If you got them hooked to a TV, it would make sense to have some sort of automatic on/off (12 V trigger or signal sensing) either way, because there usability is usually more important.
