My NAD 356 BEE DAC suddenly stopped giving sound to the speakers. Pero gumagana yung subwoofer connected to the Pre-Outs. Dati nangyayari lang to kapag napipindot yung Speakers A/B. Pero ngayon kahit pindutin yung Speakers A/B eh walang sound pa rin. May power naman siya and gumagana ang mga buttons ( naririnig ko yung mga relays kapag nagchachange ng source etc). Tried also the Mute button pero wala pa rin, sa Subwoofer lang siya gumagana. Hays wala pa akong budget para sa new amp haha, please help

Separate ang power supply nyan for the amp section, so everything before the amp section will work even if the amp or its PSU is busted. Could be just a dead relay, or worst case: catastrophic failure of amp.

Notorious JH and Chrissi caps could also cause the problem.

I love the nad sound, and still own some nad gears. However, parang nad has been plagued by reliability issues these past few years.

Or baka just part of the consumerism mentality na din ang nad - na parang tv/cp na should be good for 3-4 years then should be replaced na.

Napansin ko medyo hot to the touch yung chassis ng c326 ko so pinatungan ko ng case fan na naka exhaust orientation. Hopefully makatulong sa reliability.

I agree sa reliability issues ng NAD amplifiers, lalo na yung sa Classic line nila. Yung 375 ko dito, sira na yung IR receiver para sa remote, so hindi ko na magamit yung remote. Tapos yung DAC din sumabog yung isang capacitor sa loob. Di ko na pinalitan yung capacitor kasi may NAD M51 naman na ako as a DAC. Kaya ngayon ang ginawa ko kinonvert ko nalang yung 375 ko as a power amp. Tinanggal ko lahat ng saksakan sa preamp section nya, tapos yung volume control is via NAD M51 na - which is a very good preamp by the way. I also use my Violectric V281 as an analog preamp from time to time.

Hopefully naresolve na nila lahat yang issues na yan sa new Classic line nila. Yung NAD M51 ko din, wala pang signs of issues medyo matagal na din ito. Mukhan sa Integrated amps lang talaga ang issues.

Addendum: Since 2012 pa itong 375 ko. Yung power amp section lang talaga maasahan ko dito although if I wish, I can still use the internal preamp of the 375 pa din kaso ayoko tumayo minsan para icontrol yung volume hehehehe. Isa pa, mas superior yung preamp capabilities nila M51 and V281 ko.

Update
Tinesting ko mga connections sa likod. Ikinabit ko yung preout sa Audioengine A2 ko and distorted yung tunog at medyo mahina. Tinesting ko din alisin yung jumpers sa likod and directly ko isinaksak yung cellphone ko and sadly walang tunog. Sayang, di pa naman ako marunong masyado sa repairs. Iniisip ko kung iuuwi ko nalang jan sa Pinas then jan ko iparepair. Kung ok pa sana ang preamp eh bibili nalang sana ako ng poweramp, mura kasi Emotiva BasX A300. Naka exactly 3 years naman saken tong Nad, nakakaiyak lang

Sir mukhang preamp section nga yun sira. Na try nyo na yung power amp section? Basing sa signature nyo can you connect yung fiio x3 nyo directly sa main in nung amp? then gradually increase the volume po. see kung may tunog.

armymanhaha · « **Reply #667 on:** Oct 04, 2017 at 02:13 AM »

Or you can take it to the next level and remove the cables sa preamp section ni 356. Ganun ginawa ko sakin to convert it to a pure power amp. By doing that I effectively bypassed/disabled the A and B switches sa harap, parang NAD 275 na talaga siya. Baka makatulong yun sayo sir.

splucktearse · « **Reply #668 on:** Oct 04, 2017 at 09:37 AM »

Tinesting ko na sir yung poweramp section niya. Cellphone lang tinry ko ikabit dun sa main in after ko alisin yung jumpers from preout2. Wala pa ring tunog

splucktearse · « **Reply #669 on:** Oct 05, 2017 at 01:10 PM »

Ano kaya magandang gawin ko dito? Worth it pa kaya na ipa repair ko to jan sa pinas?

armymanhaha · « **Reply #670 on:** Oct 06, 2017 at 12:33 PM »

If i were u i would have it repaired. It may be the last class a/b integrated amp from NAD now that they are moving towards digital amplification.

I was able to home demo a NAD C368 Class D amplifier. It didn't sound good, "manipis" ang tunog. My Brik integrated amp (also class D with only 20 watts per channel) sounded a lot better.

I had the same observation with the NAD D3020 that's why I went with the C326BEE. IMO, the class A preamp stage of the NAD classic series are some of the best sounding I've heard among amps in their price range.

San ba meron NAD repair shop jan sa Pinas? Bale taga Batangas City po ako jan. Kung meron mas malapit mas ok para di na luluwas ng manila. Wala kasi akong alam na repair shop dito sa Abu Dhabi.

Wow disappointing to hear that. Binabalak ko pa naman kumuha ng C388 kasi madali talaga maginit yung C372 ko. Mukang M3 pa din talaga end-game NAD goal..

Actually the shop already warned me na "manipis" tumunog but I wanted to hear it for myself at my house.

Any idea guys kung anong best na DAC to pair with a 356BEE(without DAC) bukod diyan sa DAC na kasama ?

I am using Cambridge Audio Dacmagic 100. Mas lamang siya ng konti sa details and smoothness compared sa dac ng 356bee ko. As per my ears yan ha. Mas sweet sounding ng konti. Kumbaga 100 points si CA Dacmagic 100 and mga 90-95 points yung dac ng 356BEE. Hindi siya ganun kalaki ang difference.

^ ah ok. and 326BEE ang amp ko pala haha.

Maganda ang C372. Sayang kung papalitan ng same level lang na amp. Better talaga kung Masters series na or comparable.

Taas presyo ng c370 sa MP ah... hmmm, benta ko rin kaya yung c370 ko hehehe.

Arulco · « **Reply #683 on:** Jan 26, 2018 at 11:11 PM »

I've just about had it with NAD. I love the house sound and the price but the reliability. pfft!

First, it was the C325BEE switching to standby on its own and then after a while, it wouldn't even get out of standby. Now, my C326BEE turns on from standby mode by itself and while it is on, it switches the the source to CD by itself. I connected my source to the CD input to overcome this behavior but now, the sound is intermittently cutting out. What the hell.

Anyway I'm going to shop for another brand since, like my previous C325BEE, this 326 is starting to show signs that it'll probably die sooner or later.

I'm currently interested the Musical Fidelity M3si and the Rega Elex-R. I wonder which of the two is closer to the class A/B "NAD sound". Not interested in any of those class D amps.

Edit:

Okay, now the music is cutting out often and the source keeps on getting stuck to CD. This amp is now unusable. No more NAD for me.

Hehe I remember the anger na naramdaman ko when I experienced the same thing with my 375. I feel you @Mr. Bungle. Very frustrating nga yan!

Although I wouldnt dismiss Class D amps at all, especially that Hypex and IcePower are gaining greater respect sa audiophile world. I currently own a circa 2010 Class D amp from W4S (IcePower, 500w@4ohms) and it sounds glorious with my Dynaudio Focus bookshelves. I wouldnt even consider it sounding 'thin' although admittedly may pagka analytical siya pero it makes my head bob and foot tap more often than my 375 could, meaning mas okay yung PRAT ko when use the W4S as power amp.

Pano pa kaya yung mga mas modern iteration ng Class D?

Arulco · « **Reply #686 on:** Jan 27, 2018 at 07:42 PM »

@ armymanhaha

I will be auditioning some gear soon so I'll probably check out some of the current offerings for Class D amps within my price range and requirements. If they can be as musical and warm as per my personal preference, then why not. My LS50 speakers are already unforgiving with bad recordings so I was hoping for an amp that can pack bit of a punch while still being refined enough to take some of the edge off for marathon listening sessions.

im a proud owner of NAD326bee, maganda naman ang sound para sa akin- very musical. kaya alaga ko lagi para d agad masira. my kumot pa nga pag d ginagamit. btw, with due respect, not all NAD amps are lemons. just my opinion po. sorry but im still a fan of NAD amps. dami ka namang choices na ibang brands kung ayaw mo ng NAD, hehe. i thought this thread is for NAD fans. kanya kanya din talaga ng taste.

Nad fan din ako for over 10 years now, at least I used to be. Just peeved kasi pangalawang NAD ko na itong magkasunod na nag fail. FYI, alaga ko din. As in tinatakpan ko, din ng dust cover, etc. Pinatungan ko pa nga ng computer fan na pa exhaust doon sa vent ng hot spot just ko keep it from overheating. It was never my intent to generalize or to bash your favorite brand pero siguro kung two in a row nangyari sa inyo sir, medyo mapapaisip din kayo. I can't help but be disappointed with my experience. Last I checked, this thread is for NAD owners too and PDVD is a discussion forum. As long as we abide by the site rules, we are free to share our knowledge, experiences and feedback. Good or bad.
