No doubt, because at times Joni Mitchell and Neil Young can sound pretty bad too, in exactly the same way. Just the same with my previous amp too... that's why my cd player is in pieces on the kitchen table right now 😉carlosfm said:

I see you have good taste.
"Harvest" is impulsive.
Excuse me, gonna listen to that right now.
PS: the hell with the silicon, just concentrate on the music. If it sounds gorgeous, then the silicon is good.😎
Harvest is the very album! I need more Neil Young, so I'm Ebaying Harvest Moon, as recommended by someone. Also my Dire Straits collection is about to quadruple 😉
Apologies for posting OT
Back on topic, sort of - should I be nearly wincing on the loudest Norah Jones (Come Away With Me) vocals? I need to know how bad this production is, so I can know how much damage the playback system is doing...

You should listen to Neil Young's "Unplugged" on vinyl.
I bought it in 1993 and it's still mint, so mint that some people think it's a CD playing.
I have much older vinyl in as good conditions.
I don't know how people treat their records.
And then they say the problem with vinyl is the cracks and pops.
Rule 1: don't ever lend your records to your friends.

She enters you ears with impressive power but without a hint of aggression.
Her voice stays in the air, you can hear the acoustics of the studio.
I love the way she makes those "falsetos" (is this the word in english?).
This shows that she's a great singer, much better (in my oppinion) than Diana Krall.
If you wanna hear the same thing in a male voice, listen to Ben Harper.
Great voice, great guitar player great music!😎
They extract the best out of your system, and out of your silicon.😀
When I modified my Sheng Ya cd-s10 player I tried following opas:
1.ad826
2.ad825
3.opa627
When everything is opa627, highs is not naturall,too many.Was no oscillating,I checked it with oscilloscope.But I found following solution: ad825 i/v +opa627 the rest (filter+out).Now sound is just beautiful.I found ad826 is little better and faster in i/v ,but I use it already for my headphone amp and I like it very much,so I deiced to stay with ad825 (difference is really subtle between 825 and 826).So my conclusion ad825 is better opa627 in i/v circuits.But when I try to put ad825 in filter or out,it looses opa627.
But all is better opa2604 or opa2134🙂.
Actually bit about original Sheng Ya config:
opa2134-iv (really not wise)🙂
ne5532-filter (low noise,very low noise,but sound is so so.May idea was create after i/v low noise circuit but ne5532 isn't good sounding amp,even with low noise.):I have it proved on my headphone amp,ne5532 was looser.
opa2604 (pre-tube out) -no comments.

A very fast op-amp always gives better results for I/V conversion.
Like a current-feedback LM6181, removing the cap across the feedback resistor.
Unfortunately, very few CDPs have separated I/V from output buffering.
The bright thinking guys that make them usually decide to put double op-amps (one per channel) to make I/V and buffering.
You can't separate them.
In the end, it's always a compromise.
Or make your own complete analog stage.😎

I've removed my 2604s and the 220nF bypass caps I forgot about (there was no cap from v+ to v- it seems).
I have soldered in turned pin sockets and bypasses of 33uF/50v Panasonic FC.
I put the 2604s in, so I can get used to the sound of the new bypass and socket config. Amazingly, the player still works! Hopefully I'll have something interesting to say soon! 😀
In the meantime, if anyone over here in the UK can tell me where I might find some of these other good op-amps (ad826, lm6712 etc.) I'd be grateful, as Farnell don't really sell them (I do have 2132 from them).

Is your CDP using cheap diodes, like 1N4004s? They can put a bit of a white-wash/glare on the sound. Another easy upgrade path perhaps.
Gaucho said:
Hi guys!
I'm courious,if diodes play big role in sound? In regular power supply frequency is no more than 100hz,which is extremely easy to handle even for non-schtoky diodes.So my question is why diodes can affect sound? For impulse power supply it is understandable,but for analog not.
In some cases yes, in other not. You can't ask simply, but with concrete example. But here you will hear " YES " 😀 .

AnthonyAsh said:
Good morning all,
Gaucho, one of my mods 18months? ago was to replace some of the diodes with schottky types, as per Thorsten Loesch's recommendations on TNT Audio. This did reduce the white noise effect on the top end, making it sweeter and cleaner... only to a point though.
AnthonyAsh, sorry that I cannot answer your searching questions, but I can confirm that in at least one line of mass-market cd players, diode choice affects sound. The improvement is actually reminiscent of running the player off an isolation transformer - sweetness, detail (correctness).

Hi Carlos,
Almost all broshures described Hexfred and schotky behaiviour in switched power supplys,and for me it is no question,they are better in this case than normal diodes.But no info about analog power supplies.For frequency around 100hz .
In my amps I know to make quite usualy SNR over 120 dB with bloody normal diodes. In our country is mains frequency 50 Hz. What is in Portugal ? 20 kHz ? 100 kHz ? 500 kHz ? 😉
Upupa Epops said:
I also know,very normal diodes can work very well in analog power supplies 4xdiodes=100hz .As I know schotky more effective and have lower heat problems than normal diodes even on this low frequencies,but I'm sure about switching noise will be aproximately the same.Again,I'm talking about NON-SWITCHING power supplies.
To Anthony : Yes, I know, that you are talking about normal frequency, me too 😉 . But Carlos can to build problems there, where they are not. 😉
Upupa Epops said:
All that spec talk and you never listen.
Japanese brands like Technics/Panasonic make some amps with impressive specs.
I'm sure there's one waiting for you.😀

1000V at 2.8 Mhz, because of SACD.

If you can't understand why your LM4780 amp's PSU needs a snubber, and you didn't even listened (or reported) results, why would you understand this?
Your amp may measure whatever you say, but does it sound decent?
You know my oppinion.
I had listen in time, in which you still whip on the way to egg 😀 . BTW classs A+ is wery good amp.
Sometimes I was asking you, why LM's need it and I still haven't your theoretical explanation. Go on, I'm waiting...
