Proper layout and lead dress are essential for stable, quiet and subjectively good sounding circuits. This includes decoupling and proper grounding techniques.
Some circuits are more forgiving than others for various reasons including circuit gains and impedances. More attention must be given to layout as those factors increase.
I have retrofitted my voicing of the LP Standard preamp in countless amps over the years with great success. While it is ideal for each gain stage to have it's very own local decoupling, you should be ok if the first two stages share a node while the last two share another node. Anything less than that is not advisable. 22u/450v caps are cheap!
My suggestion to you is to pay closer attention to the layout and dress of KOC's projects as they are depicted. Once you have something that works as anticipated then start experimenting.
Keep at it - you'll get there!
