Amplifier Experience Gryphon Pass Lamm BAT


After living with a small integrated amp for quite some time (Pathos) I am finally about to take the plunge and buy myself a large power amplifier with a matching preamp. (Speakers are WB Chimeras)

I am focussed mostly on class A amps amd prefer a neutral sound erring on the warm side. After having lived with Pathos for a while I am looking for someting more powerful than most tube amps.

The brands and models I have narrowed it down to are:
- BAT VK52SE+ 2x BAT VK600
- Pass Labs XP-20 + XA160.5 Monos
- Lamm L2 Reference + Lamm M1.2 Reference Monos
- Gryphon Mirage + Antileon Signature Stereo

All models are used or ex-demo equipment I could get a good price on hence if some manufacturers (Krell, mbl etc.) are not included this is because there is either no opportunity or I excluded them for some other reason.

The above are listed according to price I could get them at with the BAT being quite a bit cheaper and the other three being quite close.

I will not be able to compare any of the above in the same room, etc so I would be grateful for any direct experience people have in comparing the above!

Since you are in Europe, you should give Einstein pre a listen. It's tube, super dynamic and resolving, and has a touch of tube sweetness. I would pick Einstein over MBL or Burmester because Einstein is tube.

I use Einstein with BAT 150SE, the match is very nice. I have also tried Einstein with other amps, both solid state and tube, Einstein has a very low output impedance so matching to even Pass Labs which has lower than typical input impedance is not an issue.
The BAT REX uses tubes, yes. It has like I don't know 6 or so in each unit. It also uses two power cords to separate the positive and negative phase. No need for tube rolling is one thing I like about this pre. Some of these pre's you can buy then you want to go on a tube hunt for them and Bat goes to extensive lengths to make sure they put the right tubes in the circuit. There is a switch I just found out that allows you to change the flavor a bit and its easy to do, just flip the switch and it puts two tubes in the circuit that change it slightly. Both ways sound excellent and I can't say which one I like better, but I like that its that easy to do so. They also have bat packs that they sell for even more of a change if needed for system synergy. Just my liking that I don't feel the need to go down the road of searching for the Nos tube of dreams like I did with my previous tube pre. Bat has done that for me and I like it.
The only experience I have is with the Pass gear. I used to have an XA160 but traded it in for the new XA100.5. The .5 is a very substantial improvement.
Extremely happy w/ BAT VK-52SE and VK-600SE stereo amp. Going this route would allow upgrade from VK-52SE to REX and converting VK-600SE to mono and buying a second one. Outstanding dynamics, soundstaging, and instrumental tone and texture.
Hamburgcity Do'nt dismiss buying in the US and changing the voltage. I have done it several times, Conrad Johnson and Karan, no problem, Viva valve amp, major problems. Tube amps seem more problematic.

Manufacturers are producing for a world market, so they need to be made easy to adjust voltage, usually by changing the taps on the transformer. Spectral even have a switch to change voltage, you can do it yourself. So if you pick your amp carefully, you can buy on the Gon and import
