You are welcome

I agree with you 100%

The Bricasti, Metrum, as well as Totaldac while share similar tonalities as HE-1, yet doesn’t actually have the resolution, staging and especially the low extension as HE-1. While DACs with loaded bass as Mojo Mystique SE, and Wavedream that you mentioned do have that loaded and hard hitting bass, they are exaggerated, colored and fatiguing. Also In my direct ab shootout of PBD and Wavedream, which are both overly thick sounding DAC, the latter also sounds largely flat, missing depth and height, as 2D versus 3D. The magic of the HE-1 is that musical and well extended bass that is real to life with no artificial colorization from the loaded DACs. This is not to say the built in DAC of HE-1 is perfect, the major flaw is speed whose caveats could be almost all fixed by streamers/ servers as Aurender N30, yet the win of technicalities is at the cost of musicalities and naturalism. The N30 won’t make the bass overly thick as many aforementioned R2R and/or FPGA DACs, yet it makes the bass less moving and enjoyable for long term listening. There is a saying Mid Fi seeks technicalities, Summit Fi seeks tonalities. It is true that Wavedream does have superb resolution, which only maybe MSB reference and select could defeat, yet it is exaggerated and analytical. if you move above the DACs at this price range and include a broader scope of high end sources including CD transports and turntables above 100K, 300k and beyond, it is never about which one has more resolution, technicalities or details, but about which one is more convincing, musical, and real to life, making you feel like being there musically while not missing any details.

The marketing is low life and despicable which is just to call EVERY SINGLE competitor with original designs garbage even without listening while charging three times more than other builds. This is not healthy community, it is a poisonous clan, allowing only one worship and one biased opinion with even no courage for normal conversation and discussion. The market and majority of buying power will let the sound make the judgement, not your hatred and pitiful language, nor your single perspectives. There is no solely one correct design, but pros and cons. The diversity won’t be intimidated by group attacks by your brainless followers. All your lies will end when people actually listen. They might be silent to avoid the meaningless conflicts with the sour, pathetic and brainwashed followers, but the silent ones are the real community, the majority, and real buying power. I am HE-1, I am Aperio, I am Woo, I am Viva, I am Shangrila… I admire and appreciate what they each does well. I’m me, holding my one stance and trusting my own ears and user experience. I’m just me, but I’m also the community, so I won’t be threatened by the bullying and harassment from you biased followers. If the owners and buyers found these trash you mentioned sound better than your only current designs, it simply shows that your standard is narrow minded and short sighted and you simply couldn’t see what others doing well, which in turn will only hamper your growth and already limited designs over the long run.

You have no idea and certainly don’t deserve what I could contribute

Also to answer the question, Im selling nothing, what are you selling btw?

The point is I’m not hyping at all please read the my posts. I was just curious and try to understand. I also stated many doubts and weak points of these AIO. I only quoted their side of story in only ONE post which freak you out! my personal preference is HE-1> T2(own) Grand Cayman/ Aperio> Viva(owned) > Woo ( owned)> BHSE( owned)> Carbon( owned) Most people buying these “trash”, trashed Carbon before upgrades!

Even for its source segment, I read that "the signal won't pass the internal cables, panel switch nor potentimeter.", thus I can't help getting curious how does Aperio transmit the signals? Edit: I found the answer gold plated silver contacts and premium signal relay.

Their flagship Aperio is balanced discrete design

The picture of Aperio strikes me more of a source component with switching power supply rather than an amplification structure. While there has been debate over the low heat and high efficient Switching Power Supply vs. Linear Power Supply, the later has been widely held as superior sonic wise. Even many top ceilling source component as Aurender W20 has upgaded its SPS to LPS in their newer W20SE.

Nice input, yet the chasis does run hot maybe due to the fact that the preamp is class A? There are fans and some strip shaped vent on the top of the chasis for heat dissipation though. It seems as both these two summit fi AIO designs have adopted unorthodoxical and different approaches to avoid the use of traditional power amplification propably in order to keep the size more compact? Yet they do both seem to put a lot of effort in the pre-stage, the link that has been underestimated in headfi, compared to their take on the power amp.

There has been very tranparent and clear pictures of the 32000 USD base model of Warwick Aperio. Sonic wise, while it doesn't have the stage height of Hifiman Shang SR and maybe even the seperation of Stax X9000 driven by T2/ Grand Cayman with TOTL source, it does have the best low extension as well as the most normal shape of stage. While I feel TOTL AIO electrostactic systems as HE-1 and Aperio have better transducer and headphones (or most current after market electrostactic headphones are problematic here and there ), they might be limited by the geometery to accomodate the best amplification. Looking inside of the chasis, while I won't judge the components just based on the size in that many great source components are also small as Weiss DAC (but it harbours at least two nicely sealed totorial transformer linear power supply even to my non engineer eyes), however I am kind of shocked at how could Warwick Accoustic include good power supply and pre-applification section that is " a novel class A circuit that can output very high voltages with prodigious current" in that limited space, along with amp, streamer and dac, that all seem to be outstanding to my ears personally speaking. Subjectively, I think Aperio is superb sounding especially its cripy and well extended lows, yet I did notice occasionally it sounds as it is about to lose control especially in the highs and treble region, which I assume might be related to the amplication. Any professinal thoughts on this super duper high end design in a small chassis? Well it might be unfair to critize the size of Aperio considering the power amplifier of HE-1 is housed inside of their headphone earcups, lol, which I thnk could explain the lack of voltage and power as I have to turn amolst three'o clock to make the HE-1 fairly loud.

I tried to collect some pictures of the super popular high end headphone amplifier Riviera aic10, wishing for some engineering insight and professional assessment.

I was asking my engineer idol Spitzer:)

What do you think of GC versus T2?

What do you think of Grand Cayman?
