Hello. I got two pair of speakers that I have now switched back and forth several times connected to my vintage pioneer 656 amplifier, It is the Tannoy revolution dc6t se and Jbl studio 290, While the Jbls got 3x times more bass and no port noise but the tannoy sounds just so more atmospheric. Im into plans going to chance the amplifier to Rega elex r for reaching more sound quality and power.
