vtl 2.5 TL old vs. new version 6350??
The newer and older are very good! I have had both and could live with either one. You are on the right track with the 2.5 because it does deliver a slightly warm presentation depending on the brand of tubes installed but I love its big 3D soundst... 
High-end amplifier clarification?
Wolf garcia, you are correct, Boulder amps are high-end. The Adcom 565 mono blocks also are heavy with very large power supplies but they do not sound high-end. Just a case in point. 
High-end amplifier clarification?
Atmasphere, Weseixas answer is very vague plus his statement that an amplifier should have the ability to drive a 2 ohm load otherwise he considers it midfi, is misleading. But if you do some searching under his user name you will see that his sta... 
High-end amplifier clarification?
Adcom and early Parasound amps I don't consider high end. A high-end amp will provide a spacious soundstage, float the airiest highs, deliver a full but sparkling midrange, and has excellent dynamics/bass without sounding boomy. It should do all t... 
Mosfet mist?
There is nothing wrong with mosfets, many Conrad Johnson amps used them. Their rugged and require less circuitry than bipolars plus their tauted as sounding tube-like. Some of the best sounding amps I have heard use them. I could never identify th... 
what impacts the sound quality more amp or pre-amp
I think a high quality sounding preamp can carry a mediocre amp and visa versa. But without question you will want to eventually upgrade any other inferior component(s) to get the desired sound you are ultimately seeking. I would tackle the preamp... 
Best tube pre-amps under $1,000
Without any reservations I would strongly recommend the new Norh ACA-2B tube preamp for $299.00 plus shipping from overseas. Bested most all the tube preamps I have had regardless of price. Transparency, detail, and big dynamics were its best attr... 
Would you pay to listen?
Mrtennis, some of those inanimate objects you are refering to provide a pleasurable listening experience and that is the objective. 
Solid State to Tubes and Back Again
If anyone has gone from solid state to tubes and back again they have made a concerted effort to stay with solid state. It really depends on the type of music you mainly listen to and what your listening habits are. For myself I like leaving the s... 
McCormack DNA .5? Do I need more power?
Koestner, you are correct sir, there is a limit to what even the McCormack DNA 0.5 can do. Seven years ago on my above post (wow where did the time go?) I was using very efficient speakers that had a sensitvity of 102 db. It was no wonder I though... 
Audio Horizons TP 2.0 Preamplifier
Cedar, thankyou for answering my question. I called Joseph Chow on the phone and he suggested I send an email with questions. I did several days ago but I haven't received a reply. Probably just a busy time of the year. 
Would you pay to listen?
Mrtennis, thankyou sir for your difference of opinion, this is what makes the threads more interesting to read at times. Sometimes it is hard for me not to want to try other products especially ones that have been ranted over and then have to pay ... 
Amplifier upgrade suggestions
Many years ago I owned the Adcom GFA 555 MKII. When higher volumes were demanded, it would clip and I even had efficient speakers. Back then going from the Adcom to a McCormack amp was a revelation for me in all areas. 
Would you pay to listen?
To be honest, only a fool would pay twenty bucks an hour to hear a high priced system. However I just happened to be one of those fools. In fact I have paid fifty dollars just to demo a new piece of gear for a weekend. The logic behind this is, it... 
Audio Horizons TP 2.0 Preamplifier
Recently I aquired a AH TP2.0. This particular one has no output transformers. Were these transformers offered as an upgrade at the time of its conception?
