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.

I finally broke down and bought a VAC 160i, picked it up today. First impressions are very good. More powerful and dynamic than my previous separate setup (Cary preamp/VAC amp). The separates may have the edge with a creamy midrange, probably due to the EL34 Mullard Xf2 tubes. Overall I am really digging the 160i.

Agriculturist, do you know the differences between the 160i and the 160iSE?
I am sure you made a good decision JMcgrogan, I believe better parts, input transformers etc, many the same as the Statement amps. Here is what the VAC website says:
"The Sigma 160i SE (Special Edition) enhances performance by upgrading the input transformers and many passive parts to the types used in the premium Statement instruments. Greater size, detail, speed, and weight is the result."
This is also what Kevin and Brent had explained to me.

I think you will be very happy with your purchase. Enjoy it!
The Vac 160i is a great amp and I'll upgrade mine to the SE at some point.
@Wig, keep me posted on your upgrade adventure. I may be interested in moving up to the SE one day myself.
Do any of you happen to know what the combined (preamp/amp section) gain is for the 160i. Specs shows only the gain for MM at 37db and MC at 57db but not the amp itself. I am seriously considering replacing my ARC separates with a Sigma 160i but with an Ortofon A90's output of ,27mv i may not have enough gain to drive my Verity Parsifal even with the MC input option of 57db. A way around this would be to use the MM input along with a SUT like those Bob's Devices make but still, need to know what the unspecified amp section gain is.
Thanks guys.
