Just ordered two Tubulus Argentus DB-25 V2 umbilicals for my two Pass XP-25. Can't wait to get them and see for myself what they are doing compared to the stock "printer" cables that come with the phono amps.

J, if your experience is mine, prepare to have to sit down LOL. Tubulus DB25 upgrades have been a seminal moment in my system evolution.

Well, let's see... :)

But the experience will have to wait a moment longer as the lead time for production and shipping is currently 3-4 weeks.

J, Aldwin of Tubulus is a total delight to deal with, he offers a very generous 30 day No Quibble sale/return, longer if needed, A+ service and quality of product.

For me, noise is the enemy. My loom of Sablon cables, Oyaide dedicated lines and Entreq grounding, have taken my previous noise floor right down, revealing layers of musical info I didn't even know existed.

I had no specific expectations for the Tubulus, but it's eliminated another level of grunge (my Nat amps really aren't that quiet), and the effects have been startling, no exaggeration.

I wish you luck that you get my level of uptick. It should be worth the wait.

Finally received two Tubulus Argentus DB-25 V2 umbilicals yesterday. Might take another week though before I will find the time to actually try them out. So far I can say that the build quality is excellent.

J, this was one upgrade I had close to zero expectations on, yet got on w installing them the moment they arrived.

They've become a major bridge to my final sound, and totally confounded those low expectations.

Today I finally found the time to do some critical listening and do the comparison between the Pass stock 'printer cable' and the Tubulus Argentus DB-25 umbilical. The positive side of me taking so long to finally finding the time was that in the mean time the Tubulus was already installed and cooking, and therefore now already has seen some 160 hours of burning in.

To be honest, I was rather surprised how clear the differnce was.

Despite what Marc wrote about the Tubulus Argentus and what it did in his system I started the comparison with my usual rather low expectation level in regard to cables. I did have the occasional pleasant surprise in the past, but generally speaking my system is somewhat insensitive when it comes to cable changes.

Well, not this time. The improvement, especially in regard to soundstaging and imaging, was very obvious. There was considerably more air between instruments and the soundstage was noticably bigger. Also detail retrieval improved, if not on the same scale like what happened in regard to imaging.

This cable is a clear winner in my system as umbilical for the Pass XP-25 and will definitely stay. Add to this the really good communication and service from Aldwin of Tubulus and I must say that I can recommend this to all Pass users wholeheartedly.

I told ya, buddy.

Re low expectation bias, you and me. Indeed, this was something of an afterthought for me, only swung by Aldwin's sale or return.

For me, this is one of three recent changes that have transformed my sound.

I'm v pleased J that you're hearing so much of what I am.

Yes, it's definitely a worthwhile improvement - although it sounds as if the impact in your system is even bigger than in mine.

It just leaves me wondering why Pass is/was selling their amps with such an inferior stock umbilical. Especially since there are only very few aftermarket options available to improve the stock cable. Heck, I mean, until recently I only new of one, the fairly overpriced Revelation Audio Labs umbilical.

J, I guess its like everything in audio, designers prioritise some things over others.

Peter Lederman is one of the all time greats in analog. But you cannot convince him that the stock DC wall warts he uses w the Straingauge cart energiser can be improved on.

Er, they can. Big time. I know, I've spent big on a bespoke psu. And the Pass, and my Nats, can be majorly impvd w these Tubulus DB25's. Just don't tell the designers.

Ordered a second set of Tubulus Argentus DB-25 umbilicals today to also get the Pass XP-30 equipped. Let's see what the cable does there.
