Doesn't have the neurochrome buffer but it has the Purifi buffer which sure seems to be every bit as good. And a case, wiring, complete.

So you’re just here to spoil the sale of Dedbeh’s buffer boards? Obviously the right customer for his boards would be someone who wants to buy the Neurochrome boards. If they were looking for a different product, this would be the wrong thread for them.

No, I simply made the comment that it's hard to diy these purifi amps when there are commercial products available for much less than the combined cost of the parts available either new or used. It means that those selling these parts may find it hard to sell them for anywhere near what they paid. You are the one who asked for links to commercial products....

The VTV Purifi amplifier did not measure well by Amirm at Audio Science Review: VTV Purifi Amplifier With SIL 994EnH-Ticha Pro Buffer Review | Audio Science Review (ASR) Forum

Of course it was using the VTV optional "SIL 994EnH-Ticha Pro Opamp".

VTV Purifi Amplifier Teardown(SIL 994EnH-Ticha Pro Opamp): VTV Purifi Amplifier Teardown(SIL 994EnH-Ticha Pro Opamp) | Audio Science Review (ASR) Forum

The tear down shows the VTV Hypex buffer board with the SIL 994EnH-Ticha Pro Opamp circuit daughter board attached.

I am referencing the VTV amp which uses the eval-1 stereo purifi modules and purifi buffers which in fact measured extremely well on ASR. See my link above. I am not referring to the VTV amp with the hypex or any other third party buffers. The amp you are referring to above is not relevant to my comment.

I have not see a review by Amirm on the "VTV AMPLIFIER Purifi Eigentakt Stereo Amplifier based on EVAL-1, only the Purifi Demo version or the VTV with Hypex buffer board.

Do you have a link to the review by Amirm on the "VTV AMPLIFIER Purifi Eigentakt Stereo Amplifier based on EVAL-1 ?

He reviewed the eval-1 which is the same as the VTV- same power supply, same amp, same buffer.

I can buy the VTV with eval-1, take it apart and have a new purifi amp, buffer, and hypex supply for less than these parts cost directly from Purifi and for less than they are selling used. I would also have a case, wiring, input/output jacks.

I know you will now say "oh, but it's the stereo module, not individual amps", which would indeed be a difference in configuration but not in performance so who cares...
