lshannon Posted January 23, 2006 Share Posted January 23, 2006 Currently I am running a modified Dynakit PAS-2 preamp and pair Antique Sound Lab AV-8s with a pair of Cornwalls. I read an article on AMC CVT 2030s, a hybrid class A no-frills tube amp, designed by the designer of NAD's 3020 integrated amp. The review sounded nice, but continued searching failed to find a broader set of reviews or comments on it. I'm stumped, it sounds good and affordable - so why no cult following? Should I up-grade from my ASL AV-8s? Is it an upgrade? I don't even know what "class" my ASL AV-8s are, but I'm pretty sure they are not Class A. Has anyone heard of the AMC CVT- 2030S and at $589.00 is it a good deal? My PAS2 and ASL-AV8s were my first foray into tubes. I like the sound and thought I would "upgrade", but am unsure of which amp would be an upgrade, so I thought if it says "Class A" I would likely be moving in the right direction. Any advice would be appreciated. Thanks, - Lee Quote Link to comment Share on other sites More sharing options...
tillmbil Posted January 24, 2006 Share Posted January 24, 2006 Never heard of them so good luck. There are probably more recognizable amps out there we could recommend though. You might want to start with a pre amp change first. Those Dynaco preamps are starter pre's, I have a Pas3 and it was reccommended that I not put any money onto it.

lshannon Posted January 25, 2006 Author Share Posted January 25, 2006 Thanks, I had an original PAS-2 that worked well for awhile and then developed a hum.I still have it on a shelf where all of my old stereo gear goes to wait. I saw a Van Alstine modded PAS-2 on ebay and snapped it up. I really wanted to keep the vintage look in my office. I have a dyna fm tuner and the pas-2 slid in a Dynaco factory wood case.The original PAS parts have been replaced and the controls bypassed.For now I am happy with it. The Antique Sound Lab AV8s (8 watt) monoblocks are nice too, butthey were such an improvement over the Carver amplifier I was using before (when I was young and thought more watts meant better sound), that I started to wonder if I could get an even more dramatic improvement with better tube equipment. I read that they were really intro tube gear and better sound could be had.I thought of buying an old HK Citation II and sending it out for refurbishing but then thoughtthat I might get mroe bang for my buck by buying new.Here is Van Alstine mod info below:http://www.avahifi.com/root/equipment/preamplifier/super_pas_3_rebuild.htmQuote: "The basic rebuild kit consists of our new RIAA phono preamplifier circuit board, our new straight-line output preamplifier circuit board, our new six section power supply board, all of the parts for the boards, and stepped precision volume and balance controlsover 100 new parts including all precision film audio circuit resistors and capacitors.

jt1stcav Posted January 26, 2006 Share Posted January 26, 2006 The AMC components are run-of-the-mill and nothing spectacular. I owned both the AMC CVT1030s tube preamp and the CD8b disc player...they did the job, but soundwise they were really no better than the Carver C-4000 pre and SD/A-450 CD player I replaced them with IMO! Plus the CD8b crapped out on me just before I got rid of it, so reliability is also an issue. Your modded PAS-2 is a fine preamp, so I have read, and your li'l ASL monoblocks, although basic, are decent amps. If you like ASL, get one of their better amps to use with your Van Alstine. Or if you're into vintage tube gear, get a Scott, Pilot, EICO, or Marantz and have Craig (NOSValves) upgrade it. Just my two cents...

MarkBK Posted January 26, 2006 Share Posted January 26, 2006 The Van Alstine mod is a nice piece - Frank's been doing mods for some time now with a good track record. You might look at Paul's amps at Bizzy Bee; www.2baudio.com as an option for amps. Quote Link to comment Share on other sites More sharing options...
SilverSport Posted January 26, 2006 Share Posted January 26, 2006 MarkBK, Have you heard any of PAul's amps??? How are the BizzyBee amps? Bill Quote Link to comment Share on other sites More sharing options...
MarkBK Posted January 26, 2006 Share Posted January 26, 2006 Not yet although he is minutes from my house. I have read many reviews and all speak very highly of the TAD product. I even contemplated selling my Mac's to pay some bills down AND buy his pre and power to still have tubes for 2 channel (most of my listening time is spent in 2 channel). NOSValve may have some comments - I believe he is an old friend of Pauls. Of course, Craig's VRD's are awesome too! Quote Link to comment Share on other sites More sharing options...

tillmbil Posted January 27, 2006 Share Posted January 27, 2006 I have heard that the Van Alstine was an improvement. I found I like my CW's better when I used higher PP type amps. I would recommend that if you did upgrade the amps you increase the wattage for the CW's. The Mc240 was is moderately a priced solid tube amp at 45wpc. I prefer it over the Dynaco Mark IV's. The Merlin for $695 is a great priced tube pre amp. I like mine alot, and the build looks great. Quote Link to comment Share on other sites More sharing options...
lshannon Posted January 31, 2006 Author Share Posted January 31, 2006 Thanks for the advice all. I am also thinking that more tube watts would be better. I think I would prefer a vintage tube amp. How is a HK Citation? - Lee Quote Link to comment Share on other sites More sharing options...
