FEEDBACK:

Portable V5:

Hi Neco,

I want to firstly congratulate you on a very well designed and wonderfully sound amp, the Neco v5.
V5 is very interesting amp as it can sound very different depending on the DAC source pairing. As my transportable, I generally use an ODAC but it did not pair well with V5, however changing to a Herus + DAC the qualities in the amp became very apparent on just how good it sounds (wide soundstage, bass texture, slam, air around notes, detailed yet smooth).

The amp was tested after 300 hours of burn in and achieved a sound signature in a transportable amp that was close to my reference Auralic Taurus MK2... A fantastic achievement.

Neco,

I received the v5 amp and so far I'm impressed. After only listening for about five hours or so (without burn-in) I've noticed improvements in sound stage, better bass response, and just a fuller and weightier and more body to the sound compared to the previous DAC/amp combo I had been using.

Thanks,

Joel.

Hi Neco,

The v5 is a very interesting amp as it can sound very different depending on the DAC/ source pairing. As my transportable, I generally use an ODAC  but it did not pair well with the v5, however changing to a Herus + Dac the qualities in the amp became very apparent on just how good it sounds (wide soundstage, bass texture, slam, air around notes, detailed and yet smooth).

The amp was tested after 300 hours burn in and achieved  a sound signature in a transportable amp that was close to my reference Auralic Taurus MKII… a fantastic achievement.

Hi Neco,

I’ve given the V5 about eight hours of use and it sounds.. Quite simply.. GORGEOUS.

Seriously.. This amp slaps! I noticed it now significantly more dynamic, controlled, and open sounding than it was out of the box... I have been in the hobby long enough to know to trust my ears... This amp is a true achievement. Never have I heard such huge sound from such tidy footprint. Niva

Received the V5 today and had a quick test, sounds great even though it still needs a good burn in. Even in low gain it drives my Beyerdynamic DT1770’s extremely well, a lot better than just using the headphone output from my ibasso DX80. No noise at all and a very clean sound, great build quality too, many thanks.

Hi Neco,

I have been using your amp for a week now and it sounds excellent.

Hi Neco,

I collected the amp this morning. It was expertly packed and is working flawlessly. I’m just sitting down to listen with it, but very very(very) early impressions are, expectedly, quite positive. Smooth, extremely transparent and natural.. And it’s very ‘fast’.. The effortless, natural speed it processes is reminiscent of better implemented tube amps I’ve heard (not the muddy, slow ones)...Thanks again for terrific customer service and top notch kit.

...the current feedback amp is another world.  Straight out of the box more involving and organic. Perhaps not quite as detailed but more complete and musical.  With two hours of burn in everything is noticeably better on the current amp.  Bigger, more intimate, more alive, easily the more correct of the two amps...

Plus 20 + hours of break-in.  This amp is ridiculous...so frickin real in the sound it recreates. But that fails to convey how infectiously alive it sounds. Music bounces, kicks, and blooms in the way I have only heard in a few other instances.  The V4  is a stunning amp but this amp is clobbering it in every regard! ..This thing just takes over and brute forces and gently finesses the Slants to obey every command the amp makes.  So much i have never heard before!  Oh my gosh wish i could transport you to what I am listening to... because it is transporting me to live venues and recording stages..

Hi Neco,

 

The amp arrived early this afternoon - thank you so much! An hour later or so I listened to it for about 5 minutes, and my first impression was that its power is inexhaustible and that there is absolutely no noise. It's a powerhouse. You got to know that I sold my Ultrasone Signature Pro and bought an Audio-Technica R70X instead, 470 Ohms fed properly by the v5 "prototype".

I noticed that v5 is an improvement regarding women's voices. I was listening to the high-resolution files (24 bits at 96 to 172 samples) that came with my AK100: Rebecca Pidgeon - Spanish Harlem, etc. Really nice, IMO v5 copes better with high-res files than v4.

...I've compared it once again with v4 with LME49710s (listening to Pavarotti). However, there is one point I'd like to mention: to my ears v5 sounds very powerful but also rather tight. It's like sitting in front of the stage (or at least very near to it), letting you feel involved but sometimes unable to get the full picture. v4 with LME49710s sounds flatter but I can see more of the landscape. With v4, the stage is larger at the cost of impact, so to speak.

In my opinion, both impressions represent valid use cases. Some people enjoy being part of the scene, others prefer the high seat. I'm lucky because I can choose the viewport size I prefer.

Possibly but not necessarily independently of this, the v5 prototype adds a little bit of color to voices, making them sound warm and detailed. This is what I meant when I said that v5 is somewhat between the OPA627s and the LME49710s on v4. Coloring is not as obvious (and sometimes annoying) as with the OPAs, but clearly audible in comparison to the LMEs. For me, this comes down to a very good compromise. I love "hanging on the lips" of singers, but don't want to miss the instruments around them.

Portable V4:

Been really burning in this amp with Jlabs burn in track. It is finally starting to open up at the frequency extremes and wow does this amp have presence. Singers pop out of a black background and just sound so much more solid. The sense of air and space is improving now and the bottom end is gaining in snap and kick as well but is the way both male and female vocalist just sound like they are there with you. We are up to about 60 hours of burn in now. Can't wait for 100+ hours on it. This amp is so quite with such a low noise floor as well. Detail just emerges with a wonderful sense of integrated musicality and flow...
...3 hours of listening and I can't stop...most involving sound I believe I have ever had...this amp is just evolving beyond what I have previously experienced...I have never heard a pair of headphones sound this good....wow...wow...wow!...
...sound is huge and extended bass keeps getting tighter and more extended with ridiculous pace and drive and absolute pitch clarity. Pace rhythm and timing are completely addictive. I can crank the volume and the phones completely hold amp. Live albums are so amazingly like being there. The venue is huge and deep and i can hear the audience around me in the recording. Orchestral Manuvers in The Dark's latest live albumn. Awesome 80's dance electronica. Sooooo.....soooo goood Neco. How do you this in such a small package.
...completely effortless. It's clobbering the V3 as much as I loved that.

Hi Neco,
I have received your amp the day before yesterday, all is well. Thank you so much...
I've put my pair of AD797 in my new amp because I didn't trust the impression I reported recently, and what can I say: my hearing must have been impaired, because they suddenly don't sound so "grizzly" anymore. In fact, they sound wide and precise but a bit less detailed compared to my OPA 627s. I can confirm what the testers on the forums said about these chips.
There is no such thing as an optimal opamp, obviously. Most of the time it seems to depend on my mood, stress level, environment, etc., how these amplifiers modulate what I'm listening to.
Anyway, I'm very happy that I've found your little headphone amp workshop. Thanks again.

Best regards,

Andreas

Absolutely great sound, and I believe I know what I'm talking about. Got an Ami Musik DDH 1, which is connected to a Little Dot I + equipped with a MUSES02 (and AEG tubes) after experimenting with millions of other OpAmps and tubes. I'm using an AK 100 as a player. Up to now, I've been using a modded iBasso Anacona D12 or a Teak HA P50 as mobile devices for listening with my Hifiman HE-560 or my Ultrasone Signature Pro (as well as other headphones and in-ears such as Sennheiser IE 800s).

I replaced the AD OpAmps with OPA627s though because the ADs don't make sense in my chain; they're very detailed and analytic - that's great but with analytic headphones they're rather harsh most of the time. They should be perfect if you're a Sennheiser or a Shure addict.

As you can see from the attached image, I've replaced the screws with black pill-style ones. And I've ordered a thinner but longer volume knob.

This headphone amp is made with love to music reproduction. Thanks, Neco Soundlab!

Hey Neco... I've basically just bought the V...ze pure amp ii, amazing piece of kit meant to be one of the best ! But comparing it to your amp leaves it sounding less amazing. Doing an A & B comparison I think your design is something quite special...

Kind regards
Dan

Hello.
I thank you for everything...
 like the amp a lot; it drives my headphones with ease and its already marvellously before the burning period is over :-))

...With each listening the amp sounds stronger and Senns brighten up...I did let it burn two days so maybe closer to 100. The sound continues to become richer with each listen! Like!

Hi Neco
I’ve had your amp for a few days now, and I must say I think it’s fantastic. The impressions I read from your other customers weren’t understating the build and sound quality of the piece at all. You’re clearly very good at what you do.

Hi Neco,
Please find attached a few lines on the ADA4627 with the Neco4. These notes refer to testing of the V4 with two portable setups using HD650 and IE8’s
a) Neutron Player (Android) + Neco v4 with ASA4627 with MP3’s @ 320
b) JPLAY Mini + ODAC + Neco v4 with ASA4627 with FLAC
The Neco v4 partnered with the ADA4627 makes for the perfect match. The 20v Dual-Mono design of the Neco v4 allows for the ADA4627 to be driven without clipping or distortion for a sound signature that similar but more refined than opa627/opa637. The ADA4627 delivers richness with great transparency without treble glare; it’s very agile and articulate offering a wide, deep, and taller soundstage with solid bass/ note weight and smooth dynamics.
Kind regards
Mark

...today I had an epiphany a Revelation, after the gain was increased, something else happened too, it has become beguiling involving, musical, Impossible to ignore. On Marvin Gayes what's going on the track save the children now the V4 brings me very close to tears as it should, the whole album is Marvin pleading for us to make a better world. Tears for fears woman in chains Oleta Adams vocal makes the hairs stand up on the back of my neck. what has happened to the v4? it is not just gain, its come alive
..I am not saying that I don't find it a little sharp at times with the AKG it still does, but now I am far less bothered I don't care, now I just want to listen and listen and listen. The detail is awesome piano stools squeak before people play, I can hear ray brown pick up his bow to play his double bass. why didn't they oil the kick drum pedal when Hendrix was recording. Steve ray Vaughan's valve amp buzzing away in the background awesome!
