Thank you, everyone.
I upgraded speakers into Dynaudio Temptation nowadays. But still as you mentioned, Amps are old versions in 1960s and 1980s.
I don't know how promising Temptations are and what kind amplifiers users have for making sound with Temptations.
Just my preferred sound was not vintage stuffs so I gave up Altec A5 systems. I have used Altec only for 2 months.
Now, I have Totem Mani 2 signature as well and I like them much. But I want warmer sound than MANI does now. Mani has good resolution, huge soundstage, detail sound image and deep bass. I liked it!!
But warmer and fainty sound of high frequency I expect for Temptation.
1. Tube or TR
2. I keep the preamp, AR SP-8?
3. If i choose Krell 400cx, ovrhaul needed? (produced 10 year ago)
4. Reference combination? (10 years passed since Temptation were produced. So, I believe some references.
