VAC 160iSE integrated with NOLA speakers


Given the superb home audio that I have been enjoying recently thanks to my new VAC 160iSE integrated coupled with my NOLA Metro Grand Reference 2 speakers and Synergistic Research cabling/power, I thought I would post a few brief comments about my set up for those who might be looking into any of these products. When making my recent amplification changes the enormously talented team at VAC gave me open and very insightful advice, as I hear they always do to anyone trying to set up a system with products of his design. By the way I understand that there will be a very similar VAC/NOLA set up by Mike Oltz of Xtreme Fidelity (who sold me my VAC160iSE) will be exhibited at the upcoming September 2014 audio show in Brooklyn, so there is an opportunity for anyone interested to hear this set up for themselves.

VAC’s 160iSE integrated puts out 85 wpc just like the original 160i, differing from the original in having (as I understand) a superior transformer, and also a special phono stage (that I have yet to use). It uses trickle down technology from VAC’s statement products. I had and loved the VAC 300.1a and Renaissance Mk3 preamp before the 160iSE. Given that my 87dB NOLA Metro Grand Ref 2 speakers don’t need the extra power, I decided to trade them on Audiogon for the 160iSE especially after hearing from Kevin Hayes at VAC that the new integrated performs in some ways at the level of VAC Statement products.

Having had the VAC160iSE at home now for two or more months or so, I can only say that the sound it produces in my system is truly fabulous – superb, open, rich mid-range without any edge and full of presence, great clean high frequencies. And I never find myself missing anything in the bass area compared to what I got from my NOLAs using my old higher powered VAC electronics. By the way, the NOLA Metros reach down into the low 20 hz region. I should also say that my room measures about 21 feet X 14 feet X 8.5 feet, and I understand that for larger rooms I might need more power or more efficient speakers.

The VAC160iSE definitely outperforms in very gratifying ways my previous, already superb VAC separates. And while I don’t really know the ultra high-powered VAC Statement system, I have heard it with NOLAs similar to mine, and based on that I would tend to echo Kevin’s insight about the 160iSE relative to those amps, although of course there is a big difference in the wpc output which probably has an impact in some ways. Since it needs far fewer tubes and has all its tubes out front, it is friendlier both cost-wise and logistically for tube swapping.

I should also say that I also very much like my NOLA Metro Grand 2s, with their open, 3D and natural yet detailed sound, and their (from all that I have heard) unequalled way with vocals. They are an excellent match with VAC amps. I understand that NOLA has a brand new upgraded Metro Gold version (newer even than the Gold version he introduced last year) that is a significant advance over earlier Metros. So I am looking forward to hearing those in September at the Brooklyn show.

My cabling is SR Element Tungsten, and I also use SR’s PowerCell8 Mk 3 which is a very helpful thing in NYC. I have had extremely positive outcomes using SR’s innovative UEF technology based bullets, HFTs, FEQ, ECTs, XOTs, etc. Their excellent products definitely work very “synergistically” with the rest of my set up.

Perhaps those with similar audio set ups or preferences have suggestions of interest for me. Look forward to those.

Agriculturist,

Congrats on your Vac purchase! I have some matched quad GLs and I prefer the Shuguang KT88Z from Grant, much more musical, better decay and lifelike imaging.

I'm loving my Vac 160I and will upgrade to the SE at some point...
Agriculturist,

The KT88Z Black Treasures are what I'm using now and I've noticed the best sound at the 340 hour mark. They don't have the top end extension of the GLs but they are superior in every other area.

I almost bought the Psvane TII but was warned by others not to buy them based on reliability issues and hear they a tad better the BTs.

Happy Listening!
The Vac 160i is a great amp and I'll upgrade mine to the SE at some point.
Guys,

One of my BT KT88Z went bad after 4 months of use; noticed a popping in one channel and then noted that that tube wouldn't bias. Took them all out and put the stock tubes back in.

No issues at all with the GL but no more Treasures for me unless their QC improve...
Knghifi,

The tubes worked flawlessly for 4 months and noticed the static and that one of the leds wasn't blinking with the beat. I removed all of the tube immediately before failure could occur.

Their are a few reputable dealers that have not had a GL KT88 fail but I sold mine months ago when I bought the Shuguang KT88Zs. Wished I would have kept them...
Agriculturist,

Which 12AX7 tubes are you using in the phono section V01/V02? I'm currently using Tung-Sol 12AX7 reissue because they are so quiet and very clean sounding.
Agriculturist,

I'll look into some NOS varieties as well. Try some reissue GL or Tung-Sol and you'll be amazed at the level of improvement at a low cost.
If you're wanting a neutral and very quiet tube, the Sovtek 12AX7 LPS is better than Psvane TII and the reissue Tung-Sol at $30 a pair.

Still doing my research but Pass and Hegel are a few I'm considering. It's going to be hard moving away from the Vac but more power is needed...
Agriculturist,

Those are Herbies SuperSonic Stabilizers that were used on top of my CD Player but moved them to the Vac after reading a review on the Vac PHI 200. I have not heard any improvements probably because they're too light and thought they would look good there.
I don't believe 6550 can be used in the Vac and the AH fuses are the real deal, I have them in all of my components and yes, they're better the SR.
Give the AH fuse a week to settle in, definitely more palpable and organic sounding than the SR.

Know of anyone looking for a Vac 160i?
Experiment with direction the second day, I like Cannon D or something with good high end extension and you'll hear the right direction has more clarity/focused soundstage.
You can slide the fuse tray out with a golf tee or a small screw driver and pop the fuse out of the clip which takes me about 5 seconds.
Just make sure the fuse is centered in the tray and it should slide right in.
