Hypex DIY Preamplifier Kit Review

[enricoclaudio]

The more I read the more I get confused because I see no practical use for this pre amp. Even the Schitt Freya S is a much better choice than this and it cost half.

I have connected DACs to poweramps for 10 plus years into expensive speakers. Never had a problem.

In this particular case of the Topping. Either don’t buy the model, stay clear of the brand, switch on the DAC first or if you really must add a passive attenuator in between for a fraction of the cost.

And set the attenuation on the amp to one notch below fire at full DAC voltage..

It seems like a promise sold at high price because of the name.

Watching.
If this thing added crossover ability plus routing of the two balanced outputs it'd be THE perfect solution to add to my OktoDAC for bi-amping my mains - and with little or no loss of SINAD, etc. (Esp compared to the Venu360 I'm currently using for that.) Very cool. Want That.

Is this not released yet? There is like no info or ordering possibility on their website. What is the gain at max volume?

Thanks, did not think of looking in their "DIY amplifier kit" section. so 13 dB or roughly 4. OK I guess but this seem to suggest it clips at 5 volts? Not fully sure what we are looking at I am going to assume that it's the input and this was at unity, but would have been good to see the performance of the volume control.

This seems more like a working concept to me. For this money, I'd rather have a miniDSP SHD as a system hub. I don't even have to put it together! It's not a preamplifer per se, but it has more useful inputs and includes DSP and a streamer. Who wants to go backwards with something like this?

 

[sarumbear]

Do you want me to dig up my early drawings of this pre amp?

No, I want to know what are the other options. You said this is the basic option, which means there are other options.

On their DIY website that I now learned, these are the planned option. No crossover option is listed. I am none the wiser how Fusion connect will work either.

Future add-on options: ​

• DAC (Exp: Q4 2023)
• DIGin (AES, SPDIF, Optical, USB, Bluetooth, Streamer) (Exp: Q4 2023)
• Fusion Connect (Optimized Master Functionality for Fusion Amps) (Exp: Q4 2023)
• Phono stage (Exp: 2024)
• Equalizer (Exp: TBD)

Thank you.

I was looking at https://www.hypex.nl/ and I couldn’t see anything about DIY products. Google search didn’t show https://www.diyclassd.com/ either.

There is no digitisation of signal on this device.

Analog-heads would be elated!
Bonus is the test results.

I too wonder why only one XLR input. The two outputs are good as many use subs these days.

While not an elegant solution you could get one of the Douk audio 3 into 1 XLR switchers for like $60. Gives you three inputs.

 

[pseudoid]

The two outputs are good as many use subs these days.

Wouldn't such a feature be also useful for doing variety of A/B testing of gear down-stream from it's dual XLR OUTs; to different hardware?
I gave this unit a 3. HappyPanther only because of its cost.

Maybe they will improve and update it for this preamp but there are a lot of documentation about Fusion implemented in their plate-amp: https://www.hypex.nl/product/hypex-filter-design/17

Pretty expensive volume knob for a 2 channel setup…

But where is the DSP in this unit?

 

[Worth Davis]

Output one to Hypex/Purifi monoblocks and output 2 to active subwoofer.. that Is something i was searching for years

Without any dsp to integrate them will be terrible in most situations

 

[Savi]

But where is the DSP in this unit?

There is none at that time but I guess there will propose add-on like their old product dlcp: https://www.hypex.nl/product/dlcp/16
?

In addition to the previously mentioned and unobtania Okto solution, miniDSP has had preamps with this capability for years (SHD and Flex series). And with proper sets of inputs to boot.

But you can't use your DAC via USB, only toslink..

 

[rvsixer]

But you can't use your DAC via USB, only toslink..

Well the device in question is analog out only, with your wish that one output be for mains monoblocks, and output two be for active sub. So no way (or need) to use an external DAC there either.

Depending on which of the several miniDSP devices capable of running a 2.x system, they will either have analog/spdif/toslink/aes outputs or a combination thereof (so you can run straight analog out to your mains/subs, or use your own DAC's take your pick). Not to mention including necessary DSP (even "automated" filter creation via REW measurement input).
