true that!Back in the day Nakamichi and Onkyo sounded pretty strange.

Frank: Is your AC line cord shielded?
When you added a ground wire, where/how did you add it?
Thank you ,good to hear it is still working great for you, now to convince my wife.AC cable is not shielded but is grounded (3 prong)
From memory there is a tab on the inside next to AC socket that is grounded. Soldered wire there
@Tim64 ... Still no problem with unit and sounds very good.

I usually have the preamp & amp grounded together with the added/mod ground wires - keep in mind this 'integrated' amp has been modded to just a power amp

that's a nice sounding preamp you've got there
Ill bet you $100 cash usd that you havent merely taken on the botton cover and verified the 'lytics and had them tested to spec and whether or not they are counterfeits.Well I'm at about 25 hours now. No mods or tube rolling yet. I have it hooked up to some KEF Q100 bookshelf speakers that are also new. I don't know if the speakers or the amp are starting to break in or what, but the bass like a flip of a switch has gotten tighter. It was lacking until real recent. Over all I think it sounds nice. It's in a bedroom that's 17x12 with 10' ceilings and it sounds more spacious and detailed over this week then weeks past. I've never had audio in here before so I can't compare really.
Yes, I'm running an Oldchen branded EL34's based SE amp. A truly excellent amp. I've only changed the tubes. I found that NOS Russian tubes sounded better than the PsVane tubes mine came with. This thing also sells as Aiqin an Nobsound.

I also have a Nobsound MS10D hybrid amp. It's one of the later revisions rather than the earlier ones which had issues with too much voltage to the tubes. Once more it sounds better than it has any right to with NOS Russian tubes in there

A mate is also running one in his holiday house, loves it.
My main system runs a Yaqin MC10T with upgraded coupling caps, volume pot, and a mix of NOS and current production tubes.

Then there are my EAR 834P copies from Douk Audio. I bought two of these. Amazing after tube rolling

I was rather happy with a Yaqin MS23b for a number if years too. It was noticeably better than a Cambridge Audio 651p I had around the same time

I also have a number of Chinese DACs, interfaces and class D amps. All of these punch way above their weight. The only let down so far have been bits of gear branded as Little Bear. The T10, T8, 5-1 tube buffer. All pure pieces of crap.... The T10 wasn't bad once the hum issue was resolved, it's just my Yaqin MS23b was better..... I never found better till I moved to the EAR 834P copies.
Anyway, my point is don't be put off by the naysayers. There are plenty out there willing to bash Chinese gear. Just do your research and you'll be right.
PSvane, even their general (not audio music series) grade tubes are decent, IF you can verify the ones you get are not counterfeit.currently running psvane el34
I rotate the power tubes out about every month
Ha. The only one that is worth a crap is the Yaqin. Anyone reading these posts needs to do a little research on AK about the truth of the Olchen, Nobsound, Douk audio, etc amps. The fact remains even in 2018, that ANY of the named amps are solely engineered to the cheapest Shaugan tubes in a hard core slave labor Chinese factory. Over 50% of the components, especially the 'lytics, are counterfeit (if not re-used from old stock), and the factory tubes are the worst on the planet. So mere tube rolling or 'lytic parts replacement with non-counterfiet verified tier 1 components is a null point, as the engineering and "tuning" at the dirty factory is for each amp's components on that days or hours run. These 3 main Chinese factories, using at least 12 different brand names, have been rusing the ignorant western "audiophile" since about 2005.
I did a write up on AK about Olchen's EL-34 and the ONLY one thats worth a crap vs Yaqin.
Seems this post, and many of the posters still live in a bubble where all that glitters IS gold, and ignorance is bliss.

I’m not 100% sure I understand what your comment means... but I’m Reasonably sure you owe me a $100 bucks.Ill bet you $100 cash usd that you havent merely taken on the botton cover and verified the 'lytics and had them tested to spec and whether or not they are counterfeits.
