Best Integrated, period.

There is no best,look at a Coda int, on their website.

I've never had an intergrated period.

There is DartZeel integrated on it's way, also improved VAC PHI beta is comming.
Regarding Vitus, UHF mag reviewer's new reference is Pass X600.5.
But for the lot of money there is Kondo's Ongaku integrated amp (it's my dream amp, no matter what many of you think).

Perrew, have you tried to use a different linestage with the Spectron, or a different amp on the VTL TL7.5?
By the way, as the Rowland Continuum 500 converts the AC to 385V direct current and buffers it through capacitors before feeding the result to the power supply, it should also address most any residual AC noise problems you may be experiencing. G.

Fafafion: Neodio 150 looks interesting but no one seems to cary it but France?
Ecruz: The TRL ST225 also seems to be impossible to find?
Coffeey: 6moons seems to like Coda
Teddy_bear: I never read UHF but I saw Ultraaudio still had Vitus as ref. I think the Kondo seems nice as well but bit expensive compared to the others.
Guido: I tried different amps with VTL, no change. Used Transporter direct to Spectron, that lowered the noised a lot. Still Id want just two boxes, one amp and one source=>1 IC, 2PCs and SC i.e. minimum cables.

So can someone comment on the Gryphon Gamut Vitus and Rowland?
