VTL ST-150 vs... ?

On the MF-2500 - yes, I used to own one. My opersonal opinion is that CJ comes closer than anyone else to providing tube sound in a solid state amp. CJ amps tend to be very balanced, with a smooth high end (I've owned three different models), and the 2500 is a terrific example. It can also drive almost anything.

I gave my Bel Canto C5i another listen this morning and am leaning towards keeping it or going up to the Ref500s with my Placette. It's really a great piece. Doesn't quite have that spooky holographic quality and natural texture of the VTL, but really good bass and perhaps a more versatile sound as I do listen to a wide variety of music, including a lot of rock and some hip-hop and electronica. Obviously the big pluses are the small size, cool temperature, and energy savings. Maybe I will look into W4S too..

Ff116, I am actually moving away from the Belles Reference 150A v2. It is a fantastic amp and does so many things well, but vocals are recessed and I'm looking for a little more richness and weight. Perhaps a bit too neutral for my tastes.

Still, every time I think about stringed instruments, piano, orchestra on the VTL I am fighting myself and wanting to bite the bullet and keep the hot, heavy, expensive to re-tube monster!

Interesting, I was going to recommend the Belles to you, especially with a passive linestage since it has a very high input impedance for an SS amp (100kohm). Perhaps what you seek can be found in a tubed linestage to go with your Belles - you are seeking more richness? you don't get that from a Placette (I do use a passive myself, so no problem on that front, but...)

I certainly get richness with the Placette paired with the VTL, and to a lesser degree a Pass Aleph 3, and maybe even the Bel Canto C5i moreso than the Belles. It's probably the somewhat recessed vocals that is my biggest gripe with the Belles, but that's not to say it isn't a great amp, just my personal preference.

After more listening with the C5i, it is very good in terms of providing big, clear, and coherent sound with smooth, pleasing timbre, but when I started listening to Classical it just didn't do it for me. Violins were too... high pitched? I can't explain it, just not quite natural sounding, lacking the subtle nuances. I hate to use the word "bright" because it's not hard or hot on top in any way, but whereas I find the VTL a shade dark on rock and more dynamic music, I find the C5i a shade "light" on Classical and perhaps intimate acoustics. I don't listen to a ton of Classical, but I enjoy it nonetheless. If I hated it, I could easily live with the C5i.

I'm going to try a CJ MF2500A. It's going to be either that or the VTL for now. Even if the MF2500A falls a little short of the VTL, but at least gives me some of that lushness that I'm looking for, I'll probably go for it over practical concerns.

I would love to hear thoughts from somebody who has owned the MF2500A.

Thanks guys.

I went from the ST 150 on to the 185 Signatue Mono's and have not looked back. The 185's were noticeably "leaner" sounding, even after experimenting with different tubes,
but I have come to appreciate that in my current set up.

I also sent my VTL 5.5 line stage in and had it bumped from version 2 to version 3 which made a difference.
I had a favorite SS amp for years, and was amazed when going head to head with the 185's the SS amp couldn't duplicate the bass response of the tubes. Never tried the same comparo with the ST-150 but suspect similar results.

I am not one to get stuck on brand loyalty, but I do appreciate what VTL bringss to the table (house sound if you will) in all of their gear (had the 2.5 with phono stage, have the 5.5 LS), so I will move up their food chain again when the need arrises.
