hi,

thanks for the answer. Well, all my cables are Cardas Golden Reference, power and XLR.
The problem is , HTS is a processor and not a stereo pre amp. It has however a PRE AMP mode that i am using. Some very good recordings sound nice, however when i listen to many other albums, it's like there is a noise behind some instrument right before they play. Like a cloud following them kind of.
I cant explain in details. It brings you all the sound together instead of differentiating them... Like when a guitar plays bass strings, there is like a OUUUUU small kind of sound behind right before they play. Not clean.

Now , this is a very trained ear here. Any person might think my sound is awesome. However, it's something i try to improve here. I know that the 202 is no comparison with the HTS. One is a processor for home theater.

But just trying to get answers here to justify spending big bucks for the 202....

thank you!

kalombo... Welcome to AA! :wave:

I'm a fan of Krell since a long time. That in mind...I would say Krell Evo 202 and Phantom is some of the best pre amps there is. Especially if you can use it with Krell Cast to a krell evo amplifier.
After the Evo series, I don´t know fore sure how good Krell is. A'm a little bit worried.

Krell works really well with krell...

Omerta 01-23-2015 11:46 AM

The evo line was designed around the cast connections. I had golden reference cables also and they were my favorite cardas cable until the clear came out but i would still use the cast connections over the clear.

kalombo 01-23-2015 06:43 PM

thank you for your answers. I will test the cast after purchasing the evo 202 etc.. However right now my biggest issue is how big the sound improvement will be between the HTS 7.1 run as pre-amp and the evo 202 ....

Tand 01-24-2015 02:58 PM

Hi

I have the 202 today and I am very pleased - but has anyone compared the 202 and the Evo Two?

POL80 01-26-2015 02:03 PM

I've had these preamps in my set:mark levinson 32,krell evo 202,pass labs xp20 and audio research ref 5 se.
The krell evo 202 was the most honest of these in my set.
With honest I mean that the krell 202 is faithful to the source.
The 202 adds nothing and leave nothing out.
Thats how a preamp has to be:yes:

kalombo 06-16-2015 08:35 PM

thanks masterlu

I have had my Krell EVO 202 för many years. Now it's running my Gryphon Amp. I think 202 doing a great job. I'v heard it i som other set up's and I like it. Maybe one of the best products from Krell ever.

But I can't help thinking about what would happen if I use a Gryphon Preamp
instead? Synergi?
Perhaps Gryphon end Krell works very well together? Yes they do, but better than Gryphons own pre-amp???

sprudel 11-12-2017 06:50 AM

Why not try my friend,:yes:

kalombo 05-27-2019 06:42 AM

I have the Krell Phantom double chassis preamp and it is amazing.

rwwear 06-26-2020 07:15 PM

According to my friend at Krell there is no real difference between the 202 and the Phantom except for a couple of small changes in the power supply. There is little or no difference in sound according to him. The new Illusion is the same except for the cosmetics.

dbeau 08-30-2021 08:25 PM

Very reassuring thread - thanks
I bought my Krell Evo 202 many years ago and never felt the the need to change even though all the rest of the kit has been - but I have wondered. I'll stick with it

Long time no see... in this thread that is.

I started this thread due to my interest in newer Krell models. I used Krell KAV 300i in the end of the 90'es. I loved it and compared it to a lot of other brands but nothing was better i thougt. When I had the posibilities to use poweramps and pre- I bought evo 402 and 202 as a start. Never was 100% comfartable with evo 402 as I thougt was a bit to clean an gray in the sound. Therefore Gryphon were better during that time. But I look back in time and compared manyu differnt brands also with alder units. I liked FPB and KCT even better. I still own evo 202 and also KCR-HR but du to my taste and testing krell FPB and KCT Preamp is the best Krell ever made.
Therefor I decided to build up my system with these parts.
I us Tri-amping: Krell 400cx, Krell 350mcx (monos) and 400mcx (monos). Krell Cast from preamp-KCT to monoamp 350 and 450, Nordost Valhalla XLR to stereoamp 400cx.
This suits my system very well I think.

With small modifications (extra subwoffer etc), this is how it looks today.

I moved 400cx into the rack and you can se the subwoofer at the left.

From the sweet spot.

Below you can read and look at pictures from some years ago.

For quite some time I'v been looking for some Krell amps. I like the idea of Bi-Amping my The Sonus faber. I like the sound of Krell FPB very much. The problem is that they have not being produced for a long time, for around 15 years.
So, I have to search for used units. It's not that easy. A lot of things have to fit into my demands. Safe by in any aspects, units in good conditions, it should be one of my FPB candidates models that I think suits my system and so on.

At first I thought a pair of 350mc or 450mcx were the only options. But I found a 400cx in very good condition. I tried it and was impressed. I tried it solo so that I could hear what it really performed. It was very close to my 350mc. It's the same amplification as 350mc apart from that 400cx has got more watt-power but a transformer that supports both right and left channel. I think most people would be impressed actually. At least my friends that were helping me evaluate it.

https://i.postimg.cc/PJgVhwy7/49U4845.jpg

Now the plan is to use 400cx for my 15`woofers, 18-80Hz and 350mc 80-30.000(+) Hz.
I have to try this more careful but I think 350mc is better from mid-bas and up, a bit more transparency, air, and holographic depth. And 400cx has got more power for the lower end.

https://i.postimg.cc/bvmpkwhJ/49U7438.jpg



I'v got three more questiens to answer.
Preamp, speaker cables and interconnection.

Preamp: At the first I had 2 preamps. Krell KCR-HR and Krell evo202. Both re good but KRC-HR is more fun. Krell evo 202 has the Cast connection to the FPB amps.

https://i.postimg.cc/pVZZbzDQ/49U9353.jpg

https://i.postimg.cc/bN5tjcvG/49U3393.jpg


KCR-HR lack the possibility to biamp... but Nordost can build a special cable with a split so that I can use biamping. I bit complicated I think.
Why not try Krell KCT preamp I thought? Ok, found a used one in good condition and tried it.

https://i.postimg.cc/25S3PJj1/49U7442.jpg

https://i.postimg.cc/ZYd0t6mx/_49U7448.jpg

https://i.postimg.cc/0y8Nw3wV/_49U7450.jpg

It's actually a god mix of KCR-HR and Evo202. Still fun to listen to with very good bas ability and at the same time more open than KCR-HR from lower mid to treble. It's also more transparent. It lacks a bit power in the mid bas compared to KCR-HR but it's still enough to hit you hard in the chest. It's over all more open and voices are a bit more pronounced.
I like it and it also has CAST and ability to Bi-Amp The Sf.

https://i.postimg.cc/MpdpbD0q/_49U7452.jpg


I'm not done jet. I have to make another round with Evo202 and KCT. But so far KCT is the candidate on top.



I just want to point out that these three preamps are good and I could live happy for all my life with each of them, but since I think it's fun to really figure this out I will consider every aspect of the sound the way I like it.
To try them side by side is really interesting.


My speaker kan use three speakercables. Deep low (18-80hz), low and Mid-Hi conections.
https://i.postimg.cc/nc64fqC4/49U7459.jpg

Speakercable: I have to think about this. I use Nordost overall in my system. Of course Nordost Odin would be the best option, no doubt about it. The Odin I'v got has to run the low and mid-hi and I thinking of another cable to deep low. I will try different cables with good low frequency ability. We will see how this turns out.

Interconnections: I decided to go with the Cast option and try to find Nordost Cast cable that is slightly better then Krell Cast cables. I'v got some Nordost Cast from earlier days but they are a bit short.

Are those two piano strings properly tuned? :D

:thumbsup: Yeah, send them over.

Sometimes you have to push the limits to achieve results. When there are no strings attached it's to much. Until then, I strech and tune.:smoking:

Carl, I somehow missed this. The photos and your comments are very interesting. Your gear is beautiful. These vintage pieces designed by Mr. D'Agostino are very beautiful and the best sonically. I enjoy your photography very much. If you see this post look at the Mac Forum. I am making a huge purchase of Mac gear.

Best

Charles
