Hi viethluu,
So I agree with you regarding the preamp influence..
I have been involved by high end audio equipment since the beginning of the eigthies...
At that time the worldwide market niche and audiophiles education have established listening audioexperience reports within high end reviews..
We were talking about the value of the sources as priorities...
Pioneer like audioresearch , mark levinson or conrad jonhson have achieved numerous of preamp and their upgrade to improve subjective listening performance.
I remember of night comparison between Marklevinson Ml1, audioreseach sp 6,sp 6a, sp6c sp8 and sp 10 vs conrad jonhson premier two premier three ...and so on.
Basically there are complementatity or not...
Audioresearch design oriented with clarity, details and focus and C0nradjohson appecied for aeration ,sounstage and natural treeble...these philosophie for each company has been maintened since the beginning..
The experience show that a link beetween a transistor amp linked with a tube preamp may be an advantage to combine the matter and weight of the note given by the pre to the bass acuracy of the transistor amp..
As a result it prooves far more difficult to bring into focus a good preamp vs an amp...it is a definite rule well known by the worldwide specialists..
To date ,preamp culture and know how has disepear since the input stage doesnot include anymore high range Phono MC and MM..
Marketing reasons to make savings have oriented the audio company to " simplify'" the design in bypassing preamp since high end is costly...
Vintage preamp unit like Conrad jonhson Pv 10 a PV 11, Pv12A or premier series are among the best opportunity ta acquire universal preamp including phono or not..
Keep in mind that the hierarchie in hifi system is.
