pass labs xa30 to valve amplifier.


hi all, i have the above amplifier direct to droplet cd player and zingali 20.6 ( i think thats model number) , chord anthem 2 xlr and epic speaker cable. no preamp as droplet has volume control.

ive been thinking of valve amps recently, but have never been able to hear one. the pass is excellent but i was wondering how a valve amp would change the sound. would a valve one have the same level of clarity and detail? i have heard valve amps offer a more laid back, spacial sound, with emphasis on soundstage? wht kind of price range should i be looking at to better the pass? any thought?

I think I know what you might be up to. You want to experience Lamm, both hybrid and all tube( sorry, valve), and VAC, that's Valve Amplification Company. Both American.
Lamms are just great, they would be my choice if I could afford them at least second hand, or third one for that matter. They sound bloody awesome. I know that many think very highly of VAC too though it probably won't have Lamm's drive and dynamics but will have magical midrange and highs to die for. Lamm of course is extremely good in this department too.
Both are expensive but might last a lifetime.
God save the Queen and her subjects.
I agree with Pubul57's recommendation of an Atma Sphere OTL amp, a great choice for clarity, detail, speed and enough tube bloom.
defride. thank you for the pointer. ill check that for sure. from their website, they sell the xa30.5 so a comparison could possible made there. im not too far from there too. if anything, i might be able to hear a quality tube amp to get an idea of what all the rave is about them. the droplet, incidently has valves, and sounds really good. perhaps partnering with a valve power amp might be of some benefit. any thoughts, anyone. thanks.
A tube pre can change the sound a bit, but in my experience the tube experience and the distinctive sound of tubes comes much more from the tube amp / speaker relationship than a tube pre. You have a great amp, so if you want to experiment, I think a tube amp or integrated tube amp would be the direction I would go. IMHO a tube preamp won't give you enough of the tube experience - which does not mean a tube preamp and SS amp can't sound wonderful, but IME it is not the real tube experience that tubeahololics love.
hi, i did consider a tube preamp. would that change the sound? im not saying the sound from the pass is not good, it is very good indeed and even over 4 yrs listening to it, it still pleases me hugely, but as mentioned before i want to experience the tube sound for the first time to see what all the fuss is about. are they really that good? if i went for tube amp or preamp, if worthwhile, i guess the chord anthem 2 xlr would be unusable? any good preamps? thank you.
Have you ever considered a tube preamp or do you want to stay direct from Droplet to amp?
Pubul57,
I agree with you,simpler design(fewer parts and minimalist approach) + quaility execution/built = better sound. I once believed the more power the better(can`t have too much power school of thought). I was wrong.
The good thing is you do not need a lot of power, which is a good thing with tube amps, lower power is generally simpler, fewer output devices, much less money, and I have always found that with the same basic circuit, less power sounds better than more power if it is sufficient power for you speakers.
i think that ear is not that expensive( relatively speaking) but its a matter of finding these various gems in the uk. i have heard of the brand. i dont mind travelling though to get something i really like. thanks for the response, very much appreciated.
Are the EAR integrated expensive in the UK? They have a 15 watter that is said to be wonderful, but I have never heard it.
thank you for the reply. its exactly the - bloom thing spatially - im looking for for. thank you for the atma sphere recommendation. ill check on the net for further information. both sound they might be hard to find in the uk, but ill look into it. yes , its really surprising what 30 w can do into Zingalis. the dealer i purchased the 30.5 promised they would deliver loud levels without distortion and he was right. initially i was not sure as i had a monster x350 ( 350 w ) pass that i sadly trashed by connecting a subwoofer incorrectly. pass are really good but that caution should be explicit, in red , in the manual as incorrect connection will damage the unit! thanks again.
Hi James, as you're in the UK I'd suggest contacting Anglesound Audio near Watford. Always looked after me and does Pass along with a number of tube brands, I've heard Almarro sound good there. I'm sure if nothing else he'd offer you some good advice. (I'm not connected with the business, just a customer)
If the Zingali's have a highish, flat input impedance the Atma-sphere S30 OTL (stere amp) would also be worth considering - 30 watts, Class A, triode, OTL. Given how little power you need, these would give you a very good idea of what good tube amps can do. I owne their M60 monoblocks since I need a bit more power, but hard to beat an OTL with appropriate speakers. Both RM and S30 are revealing and incisive in the way that good SS can be - neither is tubish in the derogatory sense, but they do the bloom thing spatially that is quite addictive that SS has a hard time replicating.
Thnk you Pubul57 for the reply and recommendation of valve amplifier. yes 30 watts drive the Zingali to very high levels with superb clarity. im told the zingali are very sensitive so 35 watts would easily be enough. ill investigate music reference. anyone with other suggestions? i would like to hear them. many thanks again.
Since 30 watts are enough to drive your speakers, I would consider the Music Reference RM10 MKII. I've owned both amps and it would be a good contest to see if tubes are your cup of tea. Your XA-30.5 is the finest SS I have heard (Alpeh J not bad either). A new RM is $1995 - relatively cheap, point-to-point, EL84 based tube amp with 35 watts into 8 ohms. A very neutral, revealing amp.
Thank you for the replies. im in the uk and to listen to one or two ill have to travel half a day, and that will be most likely from the same manufacturer at one location. hi end audio dealers have been in decline for years here. my pass labs 30.5 sounds extremely good and there is no complaint in the sound department. perhaps its over detailed but i like the sound that way. i want to experience a tube amplifier that is in the same calibre as the pass,or even better. to date, ive never heard a single note from a tube amplifier. anyone point me to manufacturers that make good ones? thank you kindly.
Here in the US, in the '80s and early '90s tube (valve) amps started to get more popular again. A lot of these models were mellow, and a lot lacked detail. Nowadays, they have a variety of different sound characteristics. I'm not familiar with the one you mentioned, but the newer ones can vary quite a bit.

Some newer tube amps may have too much detail, for some people. Newer coupling capacitors, and other parts have changed. A tube amp still seems to have a midrange that a lot feel is more closer to real, than a solid state. That is were most of the music is.

They use mosfet and other (transistors), to try to replicate tubes. And, a lot of these (solid state) are more laid back sounding, than some tube amps. So these newer tube amps can be more detailed than the average solid state. You really need to compare them, and I mean various ones to get an idea. The combination of different gear will influence the outcome too. Just hearing one or two won't give you a real idea in my opinion.

It still depends on the listener. I guess we vary more than the amps do. I use both. But, I lean toward tube amps for serious listening. A hybrid won't get you there, nor just a tube preamp. You need at least a tube power amp. And, tube power and preamp, for the full experience. A tube integrated, if done right and powerful enough, may work too.
I think it is a mistake to think all valve[ or tube as we say here in the colonies] amps sound the same. I have heard ones that sound as you describe and others that sound more upfront and brighter than my own SS gear. I would focus on a perticular amp and how it compares with your present amp; which is very good.
