Pass Labs amps and Avantgarde speakers


Hi,

Does anyone has any experience with matching Pass Labs XA30.5 poweramp with Avantgarde Acoustic Duo speakers?

The XA30.5 is getting great reviews all the time but in my part of the world it's a little hard (say impossible) to audition on my Avantgarde speakers before buying.

My plan is to drive the XA30.5 directly from my dCS Debussy dac.

Thanks!

Best regards,

Sorry for being a bit of topic but I hope you will not mind my little story.

A few months ago I have attended an Avantgarde demonstration. I had about 1-1.5 hours till the shop was closing and my plan was to listen first the UNOs and then the DUO Grosso speakers. The dealer was king enough to switch the Audio Note integrated initially used with an Accuphase E-560 class A integrated amplifier (I own the previous Accuphase class A integrated, i.e. the E-550). I was so blown away by the Accuphase E-560 – Avantgarde UNO combo that I could not stop the music and go upstairs to listen to the DUO Grosso – I had to listen all the material I brought with me.

Since the Accuphase E-560 integrated (and the E-550 too) deliver 30 class A watts into 8 ohms you may also want to consider these integrated amplifiers.

Good luck!
For the past five years, I've owned Avantgarde Duo Primos. Prior to that, I owned Avantgarde Duos for four years. During that time, I have owned or demoed many many amps with Avanatgarde loudspeakers. I'm currently running the First Watt M2 with Avantgarde Duo Primos. The sound is warm, engaging & very musical. Very tubelike. I have pretty much owned or demoed most of Nelson Pass's Class A lower powered offerings (Pass Aleph 3, Volksamp Aleph 30, First Watt Aleph J, First Watt F2, First Watt F3, Pass XA30.5 and First Watt M2). The M2 being the best of the bunch followed very closely by the First Watt F3. I think you should really focus on the First Watt offerings in lieu of the Pass XA30.5 with your Duos, as the First Watt amps seem to be tailor made and at home driving horn loudspeakers. Good luck and let us know what you end up with.

Thanks for all the responses and suggestions! Since I posted my question in april I have been auditioning these amps:

- Pass Labs XA30.5
- Cary CAD300SEI
- T+A V10
- Border Patrol SE300B
- First Watt F2
- EAR/Yoshino V20
- DOXA 62 (handbuild Norwegian solid-state amp)

All of them have been auditioned over at least a couple of days, some for weeks and even months. These are all great amps and a number of them could have been the first choice (including the XA30.5) - it's basicaly a matter of personal taste, sonic preferences and how well it performes in your system.

I went with the Border Patrol SE300B which in my system balances everything perfectly and simply creates magic with the Duo's!
Hi Mohano,

I purchased the First Watt M2 about 7 weeks ago. I believe it is by far the best sounding solid-state amplifier I've ever heard with my Avantgarde loudspeakers. It is so tube-like and musical that I find myself listening for many hours at a time. The M2 has really surprised me. Last week I had a couple of friends over to listen. Each of them have been in the hobby for 50 years and are huge tube gear lovers. They were shocked at how good & tube-like the M2 sounds in my system. They were very impressed with the M2 and could not get over at how good solid-state can sound. If you get a chance, try and demo the M2 and tell us what you think. Nelson Pass is a genius! Take it easy
