Jeff Rowlands Amp and Dac vs. VAC amp and DAC

I mentioned Purist Audio cables. They have a cult following, not that it is the only great brand. Cables can really make or break the system because signal transmission is just or almost just as important as signal processing. If you decide to buy them new, I suggest you contact albertporter here on audiogon. He is a very experienced audiophile with incredible system, he will help you choose the right cables, he sells them too. I talked to him in the past. Purist cables need at least 200 hours of burn-in time to sound best, I can confirm it.
I think, VAC has good Chinese tubes in it, but of course one can do better with New Old Stock tubes. Most people here replace those factory installed tubes, I guess. I would for sure.
Most agree that at their best tubes sound better than transistors but this level of performance costs a fortune. At more modest levels there is no clear answer, it depends on many things including personal preferences. You could even try " poor man's LAMM " Rogue Audio Pharaoh hybrid integrated. It's $3500 new, many like it a lot. Both VAC and Rowland integrateds are what, about $11000 each new?

Rinpoche,
I had to smile when you mentioned seeking inspiration from music to fuel/assist your writing process for your book.  I find music essential for both writing and mathematical calculations - - I just find it helps bring my mind to better focus (I'm a bit ADHD, so it is nice to have music exciting and activating some itchy brain circuit to steady me down).  And I find I can do both with great simultaneous involvement, truly having some ecstatic experiences in just such times.

I am a VAC Phi 200 owner that wrote about them a bit earlier.  I have heard that the iQ is a very nice step up in sound quality, so I think you are wise to wait for that audition before making a decision.  I will bet that it tips the scales!

I have changed from the stock VAC Shuguang tubes for sound that I find better:  Gold Lion KT88's for the power tubes and Shuguang Treasure CV181-Z tubes for the input and signal tubes.  And actually I have lately mixed the original Shuguang 6SN7 tubes back into the driver station for my favorite overall affect in my system and to my tastes.  My basic point is that there are better (different?) current production tubes to try, and mixing and matching can dial in the "flavor" a bit to suit.  And they don't break the bank, by any means.

Keep enjoying the journey, and I am sure you will end up with a musically satisfying system.  (And, yes, cables make a difference, too, but let's defer that topic for now...)

I hear you (no pun intended, LOL). At first I will probably be a bit nervous about tubes, but I am sure I will get the hang of it, if I go that route. I wonder, what cables do you use with the Phi 200? 

Also, I will listen to the musical suggestions. I am not familiar with them. I have eclectic musical tastes that include jazz, classical, rock, world music, and even ...
broadway!

One of my go to songs this time around for auditioning has been Peter, Paul and Mary's All My Trials. Just pulled it from the vaults and it is a lovely acoustic song. I have other tests as well including Bach's double violin concerto, Prokofiev violin concerto #2 Andante, Diana Krall's version of A Case of You, Maria Callas singing 'La Mamma Morta', Keith Jarrett (who by the way walked out of a concert I attended last year in Paris because too many people were coughing), and many, many more. So much great music. Now all I need is an AMP!!

Question for Rinpoche.

If you had just heard any of the systems you have heard, and not others to compare to, are there any that you think you would not be happy with long term?

My point is these are all great sounding systems in their own way. Each with strengths and weaknesses like always. In the end all that mattters for a music lover is ability to enjoy the music to the max.

Personally, having heard a lot over the years, I think there are many systems both expensive and less so that I could live happily with if I had to. Yet no two sound exactly the same. The only way I can assert which sounds "best" overall is to compare to live music I have also heard over the years.

Just wondering.   It's different things that justify any purchase to different people but in the end its ability to enjoy music that matters most to a music lover, not the gear.

One of my favorite Broadway albums, featuring many of the all-time classic songs, performed by a great operatic singer:

It appears to also be available on vinyl, which is what I have.
