The earlier in the audio chain, the lower distortion should be, since each subsequent component increases the order of the distortion products of the earlier components by its own distortion.
A chain consisting of a preamp with 1% 2ndHD, an amp with .1% and a speaker with .01% will be very different from the reverse.
I keep on saying that the DrMordor TPA3255 gets the first place for me )
TAS 3251 vs Modified Aiyima TPA3251 : I prefer the Aiyima because I found it more "organic", more dynamic. ..JMF11 did not share my opinion, this is once more very subjective....
If there is one common denominator between all these amps, it is the soundstage which is great for the three models. The dual Mono Merus is much less persuasive about the soundstage, JMF11 and myself we were OK.
Now if you only consider the ratio performance / price : the modified Aiyima TPA3251 wins hands down )
Yes I2s input. You can add a BT APTX Chip as well to drive it from any wireless Audio player.

Good evening amigos,
Here is the next step concerning the Drmodor TPA3255 module (then will come the Gan and the Purifi with Custom buffer). I decided to push the test of this amp with a well-known store in Paris and Lyon. I asked 3 experts from the store to test DrMordor's module for a week on a multitude of very high-end speakers. Since the Drmodor's module has not yet been measured, the exercise is to collect the opinion of professionals in the field to get an idea of the quality of the module vs other amps in the shop.
It is a very famous shop which has very demanding customers and who have had a reputation for 45 years!
The founder will give me his expert opinion by next weekend.
I have already had the pleasure of listening to DrMordor's TPA3255 at the store plugged into wide band speakers with a deported "Pavilion", great ultra high ends speakers by the way ! It was impressive, and the customers were a little stunned.
Frankly I am confident and know these are very critical experts...

daniboun, thanks for sharing the images and the video unfortunately I know the traders well, they will never tell the truth about what they have heard otherwise how do they sell their expensive products🙂
Is the amplifier the latest version of drMordor without a potentiometer?

How many versions have you built? If it is allowed in this 3d can you post photos or links of all your products?
Thanks
Thanks
I trust this shop, I know the founder who has a solid reputation in France.
He is known to be very critical in his tests.
I know he will not give any gifts regarding his appreciation.
Keep in mind that this is a service rendered from passionate to passionate and not a test in view of selling a product)
You bought the latest version 3.
Differences: The first black can only work from 220V
The second, white, can work from 110 and from 220V
No more differences.
In the latest version, only dip op amp

The difference between 220V and 240V should be within the tolerances of most electrical devices, right?
Know them too (shop and founder), for 40 years...
Agree they do not make money by selling electronic stuff.
They are in the speakers kit business, and mostly honest (not money/margin possessed).
Concerning Purifi vs Gan (Bosc)

This has been already shared in Purifi thread. Very interesting.)
About Purifi : I will share my review by the end of the Month, we are currently developing with an engineer, a custom Buffer for the next dual Mono Purifi.
