NECO SOUNDLABS PORTABLE V.2 AMP - Page 5

post #61 of 342

Since this thread has come to a slow down, I an I can now answer my own questions....  I have now tried several op amps in this very nice amp.  I have tried the LT1028ACN8 op amps, and they are very niec, but with my source (sflo2) and earphones (ER4-S), I can't tell agreat deal of difference from the AD8610 op amp, may be a little more bass with the LT1028 ACN8, but not much difference otherwise.  The LT1128CN8 is not a good choice for me, as this op amp brings out more treble (too much for me), and less bass.  I really am enjoying the LME49710's (from National Semiconductor).  They give a smoother sound and with my set-up (sflo2, neco soundlab V2 with LME49710), my Westone 2 earphones sound really good, even better than the ER4-S's.  I am however using the cable that converts ER4-P to ER4-S with the Westones.

Just received my Neco Soundlab Portable V.2 and with only 1 hours of listening I can say that it sound amazing. The clarity and musicality this little amp produce is unreal. I got it with the upgrade ad8610 opamps and 500ma Li-ion battery. I tried it first with my DT1350 and notice the improvement in the soundstage immediately. I'm now listening to a very great Jazz album from Diego Barber with my HD650 and get a good listening volume at 9:00 eek.gif. And the bass are sounding tight and detail so power is not a problem with this PORTABLE amp.

 

I can't wait to get a bit of burn-in to ear how good it can get. I'm not kidding I think the HD650 sound better than with the Nuforce HDP.

 

Thanks to my friend Proglover and this thread I have a very good amp that will be use at work with a Dacport. (to be coninued...)

Order with AD8610 op amp option

 

in July 2010. Neco is an excellent seller good communications and timely shipping.

 

PACKAGING:  the V.2 was packaged in a bullet proof configuration.

 

BUILD QUALITY: the V.2 is built like a tank superb finish and quality feel, with Neutrik female mini female jacks.

 

SOUND: Started noticing improvement after 50 Hr burn in,DSCF2472.jpg reached max performance at about 100 hrs. Overall sound is very neutral all frequencies with a very tight and deep bass.

The sound stage is wide and deep with excellent instrument separation.I used Shure SRH840, Sennheiser HD595, Sennheiser HD600. Source AloSony D25S line out with ZXAC " SCS mini cable. The listening experience is like listening to a high quality desk top headphone amp.

I compared the performance to an Ibasso Toucan PB1 and I prefer the Neco V.2 due to it's natural, neutral presentation and superb soundstage. I highly recommend this amp.

 

The battery life appears to be over 20 hrs with normal playback.

Hmm Neco soundlabs huh.

 

Thx the opamp sound info... anyone have any ideas what I can replace LME49610 with?

 

I also need to replace TDA1308 in my Teclast T51.

 

I value detail and treble, I don't like NOS sound, if that helps?

 

Thx. :)

Just to pile onto the bandwagon -- I love my 18V "portable" dual mono amp from Neco Soundlab. It is probably the most bang for the buck I have had with any audio equipment I've purchased. In case you're wondering, my other headphone amp is a Burson HA-160D. The 18V amp from Neco rocks!!!

 

Best regards,

Adam

Neco has a solid track record.  I have one of the original versions and it is a powerhouse portable with great build quality.  The newest ones have even better specs and a nicer finish but still remain a great value.   The owner/builder is an EE in the UK -- not a third world product and it shows.

This little amp is very powerful for sure. Moreso than my Centrance DACmini. I wonder how it would compare to the Objective 2 (O2)???

post #70 of 342

Neco Soundlab V3 will be out soon!

post #71 of 342

How do you know? Do you have any details? I've been considering getting one of his BOSSFET amps to go along with my 18V dual amp "portable" amp...

post #72 of 342

Well, heard from the man himself. Still waiting.

post #73 of 342

I received my Neco V2 with AD8610 opamps yesterday.

It seems like it needs burn in for me.

V3 spotted on ebay - 18v in the same v2 case, USB rechargable, long battery life. Sounds like a winner -

 

http://www.ebay.co.uk/itm/new-V3-DUAL-AMP-portable-headphone-amplifier-/140669301618?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item20c08b3372

 

Also has bass boost and gain selection (internal) and the usual battery and op-amp optional upgrades (both look worth it to me).

 

Was a big fan of my v2 which I ended up giving to my brother and then missing a lot.

 

Once I get over christmas financially I'll definitely be getting a v3.

Hello all

 

I too , just order Neco Soundlab 18V portable Amp V3 .

will be going with all the available upgrade option he provided :

 

1. additional Battery to boost to 60 hours usable time .

2. upgrade Op amp. ** I have specially request to use LT1028ACN instead of AD8610 offered at ebay. he have responded that he felt that it is a interesting Op Amp and he is helping to source it to install for me . technically ,he confirm that it is going to work flawlessly with his Amp, except that battery life will be shorter due to higher current drawn. however , with the extra battery. it is not a issue at all .

3. Bass Enhance easy access case modification. 

 

he will work on it when he is back on 05 Jan2012 . can't wait to receive this .

 

one question that I have is on the gain setting . 

two gain setting are available : a. Gain 1 is set to 2.3  and b. Gain 2 is set to 6 . they are switchable with insert and remove the jumper beside the Op amp.

My head phones gear mostly falls below 100Ohm . ( Ultrasone Edition 8 / Grado RS1i / Beyer DT1350 / Hifiman HE500) .

what gain setting should I use ?

 

appreciate your advise and Happy New Year to all !

 

Thanks 
Raymond Lim
