Ilv, I have been using either the Pass Labs X-350.5, and recently a pair of XA-100's in my system and both have sounded gorgeous with the Placette Dual Mono Active Line Stage.
I'm a great fan of Nelson Pass designs, his preamps have alot to offer, however, in my system, the Placette allowed his power amps to really shine in my system. Guy Hammel's, that Mr. Placette, other preamp which is a passive line stage offers about 80% of the performance of the active linestage and costs $1500.00 compared to $4500.00 for the active linestage. I auditioned seven different preamps, both tube/ss, and choose the Placette because of its sonic virtues and overall performance.
I'm assuming you love your new X-250.5, Pass really nailed it in the X-.5 series, they really are beautiful sounding amps. Well, I hope you put the Placette on your audition list, you get a 30 day home trial period and Guy is a great gentleman to do business with.
I've just bought the X350.5. Am waiting for it to show up at my door any day now. Another friend also has the X350.5 and paired it with both an ARC Ref 2 Mk I and a Pass X0.2. We were over there the other day trying to help him decide which preamp to keep. It was a hard decision as some music sounded better with one than the other. The Pass actually sounded warmer and more natural than the ARC. It was a toss up. We would be happy with either one. At the end we voted for the ARC as it allows you to modify the sound with NOS tubes.
I will be mating mine with an ARC LS-25 Mk I with GNSC's (Great Northern Sound Company) reference level mod and a set of white label Amperex 7308 tubes.
Thank you for you guys responds. After I posted the question, I have tried four different preamp. First, I tried the ARC LS-25 MK I, but I did not like it because sound was not forward, may be it was not my type. Second, I tried the Simaudio moon P-3, I like this better than the ARC, sound was more dynamic. Third, because I like the P-3, then I had good opportunity to buy a Simaudio P-5 LE with fairly low price from a local audiogoner. I love it, it brings my 250.5 to another level. But few weeks ago, one of my audiophile friends bring his X-1 to my house and I like the X-1 better. I don't know the X-1 can really beat the P-5 LE, but they definitely have better match. So I finally bought a X-1 two weeks ago and plan to buy a Xono later. make all Pass stuffs.
Thank you for you guys responds.
Is there a problem matching a Cary SLP 05 with Pass Labs X250.5?
The output impedance is 400 ohms for the SLP 05 and the input impedance is 30 kOhms.
The reason I am asking is I have just tried matching my Cary SLP 05 with a Jeff Rowland 625 (input impedance 10 kOhms) over the weekend and the bass was too boomy and dirty. It worked better with a Primare A 34.2 (input impedance 15 kOhms) except the bass di not have enough slam.
