PS Audio BHK signature preamp

@audphile1 @yyzsantabarbara & anyone else

I was looking at the Simaudio Moon 330a. It is the perfect form factor for my existing space. It probably would be a compromise over the Coda (less class A etc) but would (I believe) be a significant improvement over my Warp 1. Not sure of its sound signature, but it appears to be neutral in reviews. 
The question I have is how much of a compromise would it be? How would it match with my BHK pre & KEF R11’s? 
Thank you!

@signaforce 330a is a nice amp. But I believe it might be a bit forward with your Kef. When I compared it to Pass XA-30.8 in my system I preferred the Pass. And my speakers are probably slightly warmer than the Kef.

I would stick with Coda. It has the right amount of sweetness up top and plenty of  resolution without getting cool or forward sounding.

@signaforce I am a bit conflicted in recommending the KRELL 300i integrated or the KRELL Duo 175XD (I see my old one up for sale). The reason being that KRELL is a ___show as a company at the moment, so you are taking a risk. Though people like George Myer Audio in Los Angeles can repair KRELL. Since I am close to LA I would likely go with the KRELL.

I liked the KRELL Duo 175XD more than the CODA #8 v1 and the CSiB. I like the CODA #16 over all of them. I have not heard the new CODA S5.5 but it only has 50 watts (with curent) and I always want more power with KEF.

The amp I would like to experiment with you BHK preamp is the new SimAudio 761 from the North Collection. They may sound great together. It is a better Benchmark AHB2 to my ears. The AHB2 would also sound good with the BHK. I used the AHB2 with a Schitt Freya+ tube preamp and KEF LS50 Meta and I really liked it. Though the Freya+ was not my fav gear.

So Signaforce, first let me congratulate you on your PS audio purchase. You got a great product at a great price and will be happy with it for years to come.

in regards to tube rolling,I need to tell you that rolling is an “art” you see, tubes change the sound, sometimes greatly and sometimes very little. It’s all system dependent! What works best in your system might now work/sound as well in say my system. It comes down to trail and error! I went 5hrough a number of different tubes before I found something that improved the sound over 5he stock tubes and at 5he same time improved my listening quality. The best way for you to find out what might work best is to go to the PS Audio website and look at their forums. There are a number of threads on the preamp as well as tube rolling for the BHK specifically. I am not versed in tubes so the information I gleaned was very helpful.

wheather you got black or silver, you did good and well bought!

@audphile1 Very sound advice, as it always is. However, I may try the 330A, as there is a used mint listing for $2,700… then resell if not to my liking with limited loss. I am finding it very difficult to ignore its perfect form factor.
@yyzsantabarbara Thanks. I am somewhat confused how Krell came into this discussion. Also, the 761 at $14,000 is not in play. The 330A at $4,200 is an appropriate comparison to the AHB2 at $3,500. Both have great form factors for my application. Sounds like your preference between those 2 is the AHB2.
@sandrock Thanks. I agree, the BHK pre was a perfect choice and am very happy with that decision. With the break in period over, I swapped out the stock tubes with my favs from my Rogue, NOS Siemens nickel/silver plates. While perhaps a little bright, their crispness, clarity, smoothness and bass slam is excellent. A significant improvement over the stock tubes. Will try the Brimars next for their warmth. Didn’t like the Tele’s on my Rogue… we shall see on the BHK. Fun stuff!
