Hi there.
Even though I love to hear a good tube based system, PLEASE keep your Musical Fidelity.
Up today I heard a lot of good int'amps - Audio Analogue, Lavardin, Primare, Sugden, etc. but I will always stay with MF (my first was a X-50, then an A3, now it's an A5) because no other sounds so complete being simultaneously smooth and powerful.
I am sure there will be a lot of possible solutions to your problem before having to consider an amp-change!
I'm currently considering the upgrade of my front speakers and I had already decided to go for the Micro Utopia Be's. Now that I've seen the Electra's 1027 Be I'm really unsure.
I didn't have the chance yet to hear either of them, so if anyone did that comparison, please do share your opinion.
I have two parallel installations both Focal-JMLab based.
One for pure audio: consisting of Focal's Electra 906 speakers, cabelled with "DPA Black Sixteen" to an integrated amp "Musical Fidelity A5" fed by a CD player "Arcam CD92T" (will soon be changed for a MF A5 CD) through "DPA Black Slink" interconnects.
One for home-cinema: Rotel DVD Player RDV-1092, Surround Proc/PreAmp RSP-1068, 5-Ch Amp RMB-1075 and speakers Cobalt Center, Caché 400 in-wall for side-effects and Cobalt 806 on Atacama Stands for rear-effects. Cabelling: 3prs interconnects Ixos 103, 1pr Ixos 115AV, 1pr QED SR75 w/WBT endings, QED Original for effects and QED XT-400 for center.
Thanks
